I noticed there is an ability in Dota wich is to get a % of chances to maim a target, does anyone knows how it works? I mean, what do you gain with it?
I'm not 100% sure but I think its just the item ability Orb Of Lightning that gives you a % to slow the enemy, with edited effects and values, no triggers.
There is a thing called orb of slow, and i think this is it, or they triggered it, making a percentage chance to create a dummy caster which casts slow on the unit
