3. Well it still only gives crit and listeal until you get that 5th hit off. I guess you also need to stack another 5 hits after that to get the next proc?

4. I played dota alot before LoL, and it happens to have a spell called "sleep". it does the same thing except much longer. So i can tell you since the caster will be the agressor, contrary to Zhonya's invul, this one will come at the worst moments possible and the protection from invul will probably not mean anything.

5. That's why i said complement, with both of these you eat away the enemy's max HP at an increasingly amazing rate. I'd definitely buy it in an AS-OnHit Kogmaw build. Taking the passive grievous wounds into account too, i think the stats & passives alone justify the cost of this item, it's just a massive mundo/volibear/sion/olaf destroyer for example. Other than that it could be nice in the game.
