get as much health regen spell vamp as you can. baron and blue elixir will help you get some extra ap also.

ininjastarbabies here again with another one of my builds. i like the concept of spell vamp on ap champs because you can definetly fool your enemies with the extra regen off of burst moves. i use it on champs that have high burst or assassin types that can pop in and steal health then pop out. malzahar is another good one for this type of build due to his DoT and his ult can really heal you up unexpectedly

get that extra spell vamp from the quints, get the ap from blues, armor is really only good yellow for her, red is magic pen for that early game

go full ap side with the extra health and magic resist defense ones

max your e by level nine even though you get your q first for the extra harass

just spin to win on all the low minions
