Life Steal / Mana Steal / Poison

Hi :)
I hope I'm explaining this correctly:
Poison: if for example you have an item with 30/3 poison it means it'll deal 30 damage every 3 seconds, so it actually does 10 damage per second (if you hit a mob that's what you'll see, them taking 10 damage 3 times), hence the 30/3 seconds.

Life steal: it has a chance to activate when you hit a mob, so if for example you have an item with 30/4 life steal, it won't activate every time you hit a mob, but enough times that it usually works every 4 seconds or so, and when that happens you get 30 life, hence the 30/4 seconds.

Mana steal: works exactly like life steal, so basically if you have an item with 2/4 Mana steal, and you hit mobs, it'll have a chance of activating and giving you 2 Mana, and that chance makes it so that it activates around every 4 seconds or so, hence the 2/4 seconds.

I hope you understood xD
