Just wanted to pop in and say that I really like this build. It's the "Only" strat that works for Sivir right now. AP is just plain silly. AD is functional, but there are so many others that are better at AD even with Sivirs enhanced gold farming.
A few observations I've had while using this:
*A good Teemo ruins your day in mid. The fast movement, with the little "Tap and run" poison damage is insanely infuriating. You probably want to switch out if you encounter a good Teemo early game. The only thing (pre lev 6) that you can Spell Shield is his Blinding bolt...which you can't tell when it's coming. It has no tell aside from observing playstyle. Even the mushrooms will require an Oracles for you to see. Late game, I do love running over Shrooms with spell shield.
*Tanks also ruin your day, but for different reasons. They just are able to take the hits and keep coming at you. If they're leveled and built properly, your BB will be rather minimal and not the nuke and harassment you want. Just out lane them and hope your minions can be the harassment.
*The range upgrade makes a huge difference. I'm finding myself getting kills and assists that I can't even see on the screen cause the Ricochet has bounced off the screen.
*Sona does not diminish an Aura Sivir's effectiveness, infact, I feel it boosts. Sona is no slacker for burst damage nor disables (her ult is amazing for making them stand still and eat the full brunt of your BB). In fact, Sona's auras seem to multiply the awesomeness in team fights. Massive amounts of aura stacking is not to be underestimated, and heals are something that Sivir can't do. Sivir's role remains as a pusher and minion farmer. Late game, I often find myself alternate laning 2 lanes using Teleport and Ult for speed. Pay no need to pubbers telling you that Sona means you don't need an Aura Sivir.
My personal Build is currently:
Meki + Mana pot + Heath pot
Meki -> Chalice
Boots and/or Vamp Scepter (Vamp if you're dealing with someone hitting you hard, Boots if getting away is an issue)
The boot/vamp priority is dependent on the other team. Ideally, you want Starks faster, so the general rule is:
Vamp + Recurve -> Starks ASAP
But if you're having trouble with CC or speed, then grab your boots first. (Merc or Ninja)
So the above are the obvious items for any Sivir, for the remaining 3 I leave for Aegis, Frozen Mallet, and Wards/Elixirs.
I noticed not many people mentioned Phage/Frozen Mallet here. I really like this item for Sivir because of the following: Slow Effect, Lots of HP, and a bit of AD. It's as close to being an Aura item without being aura. As an Aura Sivir, your goal is to assist your allies in whatever they need. Starks and Aegis provide some nice defense. Phage provides slow which is offensive and helps your team get the ganks.
I will be trying the Manamune to replace the Chalice in the future. That sounds like a lot of fun.
*Runes:
So...I followed the Dodge Seals, Mana Regen Glyphs part...But for Marks and Quints, I decided to go half/half with AP and AS. If figured that they're multiplicative. Your damage output is roughly Damage * AS, so you want to aim for a "square". 2*8 is less than 5*5 is the idea. I'll probably want to theory craft that some more, but that's the general idea.
Playstyle:
I love how subtle her style is. One of the key skills is learning how to cause a lane to snowball and thus dictacte where your enemies must defend. This is mostly late game. It can easily turn a losing game into a winning one when your opponents are forced to split off 2 guys to deal with lanes while your team 4v3s or 5v3s against them...or they can just watch your minions kill the towers for you.
Wards are REALLY important for Sivir. She has no disables nor slows. And she only has 1 Spell shield per "gank" attempt. So you really need to know they're coming. Wards in the bushes are absolutely crucial. More crucial for Sivir than other more durable, or faster champions with superior escape skills.
One more really critical observation on playstyle is that Sivir should always be higher level than opponents. You gotta push so hard that they miss out on XP. Remember your zones of engagement. When you are attacked, all of your minions will attack the champion attacking you as a priority. Early game, this is really important to scoring damage on your opponent while keeping in XP earning zone.
The time when her BB becomes a serious nuke is when it's at level 2-3 while enemies are still low level. Sivir needs to be a couple levels higher to be a serious threat in a 1 on 1 fight. Her BB just doesn't do enough damage otherwise. As Sivir, you need to move based on the minions. Push lanes where enemy minions are snowballing and turn them into a snowball of your minions. Follow a wave of your own to push a tower...whatever it is, aim for large XP gains and money gains. Sivir needs to out level and out farm the opposing team. If you can't do that, then you're going to fail at the aura build.
Questions:
1. Any suggestions for how to deal with Teemo?
2. Suggestions for different item builds?
3. My current summoner spells are Flash and Teleport. I've been considering switching Flash out for Ghost for superior chasing (sometimes, even sivir has to do it, or sometimes to give my chasing ally some cover). Thoughts?
3b. Does the BB+Flash combo for 3 hits work? How often have you used the combo? I've almost never been in a situation where I've had the opportunity to use it as I stay at range if I can
4. How about Rally instead of Flash? Teleport is too useful to get rid of.
In closing:
Thank you Mogri and Quikslide. This guide and playstyle has led me to Sivir as my main. I lurk on the boards and watch this thread regularly for developments in the build. And thanks ahead of time for any help people can provide with my questions.
