So Q:
gives a 10second movespeed buff! faster then Teemo w active! on all abilities
Does 14%targets life over 6sec (9.5%in first 3sec, can be refreshed) (Teemo shroom does 14.5% over 7sec)
Its on a 2.2sec cooldown with sick 80AP scalling true damage, and can be spammed infinite, since 36.66%more base mana regen then champ nr2 in the game.
So if build tanky, you can apply dot faster and longer
And when build tanky, you can use movespeed to get out after, then you have 900out of combat life regen.
Ryla would apply a 4sec slow, but you not realy need huge AP, and the 6e item full build AP is deathcap
My AP-teemo also builds Redemption from forbidden idol, if Cloud drake stacks happens!
--------------------------------------------
2000target life*0.14=280damage over 6sec
2000*0.095=190damage over 3sec
190/3*2.2=139damage in 2.2sec q-cooldown
About 174to350AP required to have same damage as Passive+Liandry
2000*0.04Ryla slow over 4sec extra liandry damage/0.8AP ratio on q = upto 100AP gained from Ryla slow if hit ones per 4to6sec.
