Yogg-Saron by Cybrok

All enemy heroes that are within medium-large range of any of your spawns, slowly lose sanity. Heroes have 100 sanity, and lose 10 per 3 seconds while within range. Once heroes reach zero sanity, target them with this ability to mind control them for 8 seconds, allowing you to control them and use their basic abilities.

Sanity is regained whenever not in range of Yogg-Saron or his spawns.

60 second cooldown

Spawns a Corruptor Tentacle, which will slow and stun nearby enemies. Casts 1 Apathy per 3 seconds, and 1 Black Plauge when spawned, 15 seconds in, and again when killed. (2 casts normally, 3 with Guardian ult).

Black Plague: Stuns the target for 0.5 seconds, every 3 seconds, for 9 seconds.

Lasts 15 seconds, 1 second cooldown, 12 second recharge, 2 charges.
