EDIT: As much as I love 20 threads on Viktor Bugs, this one contains a lot of them, try bumping this over creating a new one. It'd be nice to redirect people to this thread or one with a more complete list if at all applicable. Screenshots and video caps of these bugs would be handy.

Power Transfer Bugs/Issues
-Power Transfer will stop mid-cast and not cast if target fringed it (came just in range of the cast and ran out again). This is a big issues since chasing a target simply becomes irrelevant. Most apparent when chasing with Q on smartcast, enemy is in range for portion of time, Viktor stops to cast, they leave range, and he stops the cast, rinse, repeat.

-Power Transfer will cast, damage and go on cooldown, cooldown timer will not display, making it a case of mis-judging which skills are actually up.

-Power Transfer will sometimes "Cast" with Augment: Power up, providing the movespeed buff, but no shield, damage, cooldown or mana consumption. This one is a nice bug... I mean "feature". It's not inhibiting play, but it's still a bug.

-Power Transfer Tooltip says "Returns portion of damage dealt as shield." Appears to go off 40% of potential damage, not damage dealt. Tooltip fix would be handy, as would a display of shield returned if this is working as intended. Otherwise, shield is giving more shield than intended.

-Power Transfer with Augment: Power seems to count portion of cast animation as a portion of the Speed Boost duration. Full duration of movespeed boost seems not to be met.

Gravity Field Bugs/Issues
-Gravity Field and Banshee's Veil have a unique interaction. Banshee's does not stop the slow, however it does stop the stun. Upon stopping the stun, the slow is "cleansed" for a very minor gap.

-Gravity Field's stun cannot be cleansed by Gangplank's "Remove Scurvy". ~Fendral

-Champions that can mitigate the slow are not receiving stacks up to the stun (Yi's ultimate as an example). (This bug is from a thread dated: 01-25-2012, not sure if still relevant.) If still occurring, may be rare.

Death Ray Bugs/Issues
-Casting Death Ray, the ray will not move from a stationary point. Occasionally also doesn't deal damage on it's intended path, but otherwise a graphical error for a good portion of these. Typically due to Death Ray colliding with terrain, sometimes not. Animation cuts at times, though damage usually carries through. Will happen on normal casts, more apparent on smart casting due to mouse movement distance.

-Death Ray will stop at walls if caster did not end mouse movement on other side of wall. Whether it actually continues to deal damage to targets on other side of wall is undetermined, the visual however does stop.

-Death Ray display and area hit are slightly out-of-wack on low graphics. Might not be an issue on higher quality.

-Death Ray will sometimes have delayed damage, hit occuring upon actual hit, damage occurring slightly after ray is done.

-Death Ray has targets-hit discrepancies (something that should be hit moves just out-of-area, deals no damage). Used to be more apparent, less an issue compared to then, but still happens.

-Death Ray sometimes pierces through Banshees Veil. Possibly when enemies are hit by it twice by running along it's track. May include spellshields as well. ~PKYG

-Death Ray's animation has gap in middle sometimes, may be due to terrain. ~Zalmout

-Death Ray's animation sometimes spawns what appears to be a Maokai Sapling. This video is the closest I can find, though the sapling itself actually doesn't always appear so clearly, nor last as long. http://www.youtube.com/watch?v=WrkTkfJz848

-Death Ray smartcasting sometimes is interrupted mid-smartcast ending before user finishes the cast, this can lead to misfired rays. ~Umezete

-Smart casting Death Ray sometimes causes direction to go haywire.

Chaos Storm Bugs/Issues
-Chaos Storm's tooltip may confuse new users, as it's X damage over each second for 7 seconds, not X damage each second.

-Chaos Storm may not be dealing correct damage on enemy champs, Reduces incoming damage by 2 Mastery may be affecting this readout, but I don't think getting hits of 0 is correct. Also watching damage ping gave readouts of around 20/20/20/20/20/40/20/20 for me at one point, said enemy was only being struck by the ultimate.

-Possible Bug with Chaos Storm and Galio's bulwark, Bulwark may be procuring a minimum heal point. Possibly intentional, healing seems out of proportion, since the hits are minor 5 damage about 5 times a second, healing should be strong to start, however near end of duration, healing should continue to reduce instead of flatlining over the 5 damage. If intentional, base-line heal amount in Galio's tooltip would be handy.

-If smartcast, Viktors ult can sometimes trigger twice. (Annie also had this bug, but it was fixed.) ~Svartfisk
May be casting up to 3 times it's potential.
Both clouds seem to be dealing damage, used to only be a visual copy, but now seems to be a damage copy as well.
(I believe it's the initial burst only here, but are there two clouds actual dealing damage? Or is it only a graphic bug?)

From this thread: http://na.leagueoflegends.com/board/....php?t=2013037 ~Elfomal

-Chaos Storm seems not to apply spell vamp at any moment during it's cast (It's initial burst seems like it should apply spell vamp, though the poke-dots may damage too little to apply enough. I'm not sure if this is intentional or not.)

-Did not silence a Lee Sin that it seemed to hit. Lee Sin was just using his shield hop. ~Krytical1

-Possibly not rewarding kills correctly, being a separate unit may be rewarding as if a minion takes the last hit. ~brodonalds

-Sometimes may follow stealthed/invisible champions. Notable is Akali, where it will track her location if it's locked onto her. It used to also not deal damage to her even though it was locked on. ~Satee (Latter portion of damage lacking is my own info.)

Other Bugs and Issues
-Damage readout post-game may be bugged. Case reports over 1 mil total damage in the readout, but only 150k magic damage and 30k physical. May not be damaging anything, however may keep going up somewhere, would need testing to narrow it down. ~kYsalis

-Lulu Whimsy caused Viktor to be kitty for entire game. This may be a Lulu glitch, combo'd with lag. Further testing needed to see if it's just Viktor and just that specific Lulu skin. Conditions of bug would have to be further tested.

-Viktor has minor errors in tooltips. Graviton Field should be Gravity Field, or the opposite across the board. Hextech Sweeper image does not display, however hovering over the space still provides item description. See attachment for this error.

• Anyone have any to add to this?
• Can anyone disprove an above bug?
• Can anyone narrow down the source of any of the above bugs?
• Are there any details I missed in any of these bugs?
• Can anyone get a screenshot or video of the above bugs as proof?

I'm bumping this back to the top. Simply because it's a compiled list of bugs on Viktor. I do think lists are better than single items because they allow an easier grasp of all that's wrong without going to 40 threads looking for a specific bug.

Have to say, Viktor is one of my favorite casters. His laser often passes through people without doing damage. Hopefully Riot notices this. Lost far to many kills to this. Especially annoying during teamfights, had it pass through 3 people and do no damage.

Do those not mean the same thing? All you did was add an extraneous word ("over") into the first descriptor.

For you regular Viktor players, how often does Chaos Storm display damage dealt to targets in range? I was playing him in Dominion yesterday and it seemed to be dealing only about 25% of its intended damage over time. Perhaps it pulses damage every 0.25 seconds, in which case there's no cause for alarm at all and I'm just ignorant, but my damage sure felt sub-par at any rate.

Shifted that to another bug, rather than paired up with delayed damage bug.

Yes, I did, however they don't quite mean the same thing. A user might expect the damage every second, but it is indeed more like 0.25 seconds. This is likely a reason the damage feels weak, because it's very minor for each ping and drawn out. This means that 5-10 damage at say rank 1 every 0.25 seconds, instead of 40 damage every second. This matters in a very minor aspect, because one expecting 7 pings of 40 damage would find it not doing quite that because of the way it's set up. It's only a minor wording change to cut confusion a teensy bit to anyone who's wondering how it works.

It's not a major problem, but just a minor tooltip change. It is indeed over the course of 1 second, for 7 seconds. There is no cause for alarm, but with the tooltip change, one can expect a slightly more comprehensible explanation.

They might change the Tooltip to display that it's about every 0.25-0.3 seconds to cut confusion as well. There are about 21-28 pings for the duration I should note, and at 7 seconds duration, that should explain it a bit more clearly. (I counted 24 when I last tried to count them.)

X damage each second for 7 seconds, not X damage each second.
One can expect exactly 7 pings of damage on a single target.

X damage over each second for 7 seconds, not X damage each second.
One can expect that damage over the course of each second for 7 seconds to a single target.


EDIT: I should also note the damage is supposed to seem low-ish. It is damage over time, and it's AoE that's not limited by amount of targets hit.

Viktor conjures a singularity at the target location, dealing 150 / 250 / 350 (+55% of ability power) magic damage and silencing enemies in the area for 0.5 seconds.

So the first part is just an AoE nuke very minor silence, little question that it actually does damage, but onto the second portion:
As it churns, it deals 50 / 75 / 100 (+25% of ability power) magic damage every second to nearby enemies for 7 seconds. The storm moves faster the closer it is to Viktor.

You can assume baseline the base amount.
50/75/100 damage over the course of a second for 7 seconds means max damage (0MR enemy) that it will deal 350/525/700 damage extra. This is then multiplied per 0MR target. Again this is the base amount. While this isn't a spell that will kill an entire enemy team, it does carry it's weight in gold. Now no enemy except jungle minions have 0MR, unless you're stacking Flat Magic Pen. Always assume an enemy who wants to counter you will get to at least 100MR for 50% reduction, even if they don't. If they do, you're ready. If they don't, this will hurt more.

You might also assume max possible enemy champion targets for 1750/2625/3500 and values of that edging up and down based on enemy MR. Assume half damage fro 100 MR, then assume some enemies will lack MR, where others will build more MR. Never Ulti Galio with his shield off cooldown or up.

(Abyssal, Sorc shoes, Haunting guise, Malady altogether hit around -44MR and 40 Pen, add about 15-16 from runes for about 100MR ignored if you're stacking all of these, play with an ally Heim (-50), Soraka(-50) and Fiddle(-8) for max hilarity, countered by health stacking unless Deathfire Grasp is upped to about 50% health from at least 2 of these).

If smartcast, Viktors ult can be cast twice, providing burst twice. IIRC, Annie also had this bug, but it was fixed.

Also Deathray sometimes pierces through Banshees Veil.
I think it most occurs when the opponent is running the same direction as the deathray. What happens is that it pops the shield and also damages the target, essentially making Banshees useless against the one spell. I do not know if this has the same effect on the other spell shields(Nocturne's or Sivir's)

Okay, added those. I'm looking into other recent threads to see if I can find anymore to add to the list.

I'll bump this again, since it seems to be relevant and I see posts about Vik bugs again.

Add that Fiora gets stun animation on her, if she's ulting on VIktor's W, it doesn't stop her ult though.
