Do their passives stack?
Say I'm Teemo and I get one of each, will my hits do the regular dmg, plus the poison, plus the 4 from Malady, plus the 4 from Executioner's Calling?
I don't see why they wouldn't... unless it says "unique" or there's a cap, everything in the game stacks. Executioner's calling with Teemo is a good idea for the early game harrassment I'm thinking!
Immune To Spells
Malady is whenever the target is "attacked" by a champion, versus "damaged"---so it should only work on individual attacks, and not damage effects like DOTs.
Not sure how that works with something like Sivir's Ricochet, though (e.g., would a Ricochet bounce count as an attack?).
