Drow warrior fighting with two fast blades. Agility hero.
If you have read the Forgotten Realms you know what Im thinking.
Circle of darkness:
Can summon circle anywhere, which is completely black to enemy eyes. So you can hide yourself your allies and if you summon it on enemies they cant attack you with targetable skills. Allies would see throught this magic. Circle shouldn't be like riki's smoke, not anykind of silence. Does not do any damage. Upgrading levels would increase the size of this circle.
Drows are known to posess levitation abilities so activating this skill would be like batriders firefly skill without damage. Trees should still stay undamaged. Upgrades would decrease cooldown or/and makes active time longer.
Two options: An arrow which works like Mirana's arrow or an arrow which puts targeted unit to sleep. Sleep could be like atro's or it will just break when someone damages sleeping unit.
Dead comes in pairs (ulti):
Drizzt's two incredible fast blades will find the weak spots of enemy armor. Exact copy of Mort's critical strike (ulti).
This hero would be very interesting to play. Common strategy to gank / ambush enemies with levitation and cod.
