Is it possible? I mean Blitzcrank's Power Fist doing Critical Strike, giving 4x damage (5x with Infinity Edge)

Pretty sure the damage is compounded uniquely.

something like...

auto attack hit for 100

power fist (add base)

100+100 = 200

crit (add 150% base)

200+150 = 350.

But can it crit at all? I ask because Poppy's Q can't crit, but Nasus' can.

nasus' q can crit. but only his base damage crits i'm pretty sure. it's the same with all these.

for blitz:

hit = 100
hit + fist = 200
crit + fist = 300 (200 for crit + 100 for base damage on the fist)

I think that it is the same for all abilities that do base damage + something. it is an attack, so the base damage can crit, but the added damage doesn't.

ok thanks :]

do you think it's worth to get an Infinity Edge for Blitz? With around 40-50% crit chance? Or should I rather get more AD?

If your game goes long enough and you want to go for an attack damage Blitz, go for it.

Get a trinity force first though.

130% (I think) bonus to base damage adds a bit more, plus you get to run around all crazy-like.

I personally prefer to get some CD reduction first though. Power fist every 3 seconds is just too fun. (ie Brutalizer, Glacial shard (or the pre-combine item))
