The additional shot applies on-hit and on-attack effects at 100% effectiveness and benefits from Critical strike modifiers at 30% effectiveness.
The third stack consumes them all to deal 20 − 175 (based on level) bonus magic damage
Attack speed:
100%+42.5*0.4 = 117%attack speed at lvl18
(117+40)/117-1*100 = 34%more attacks (aa damage) from building 100%attack speed in items and runes
Crit chance
aa = 110AD + 55AD + 58magic on hit + 58magic on hit = 281 total
100%crit aa = 165AD+116magic + 110*0.75crit on first hit + 55*0.75*0.3crit on second hit = 375total
(375/281-1)*100= 33.4%more damage from aa when build 100%crit chance
Attack damage:
1300 bonus AD required to double R and E damage
(170+1.6*110+57magic) / 1.6 = 252 bonus AD required to double q damage
(110*1.5+57+57) / 1.5 = 186 bonus AD required to double AA damage
Rageblade: This damage is affected by Critical strike modifiers. (-70%damage on 2nd aa)
even when some nice items witch crit chance, without attack speed exist
Items i think can be fun:
Muramana to spam things
Mystic item: Eclipse for the armour penetrate and lethality (or Goredrinker for cloose combat) or Turbo chemtank (for pure tank)
Cdr shoes (for Ultimate spellbook) or swiftniss
Warmog and tank and haste, maybe deadmans
Black cleaver for haste/ad/tank/golddump in item
Runes:
Ultimate hunter
Cosmic insight and cdr shoes for Ultimate spellbook

Tactics:
