DoT Ultimates (with Treant Overgrowth)

Treant's Overgrowth is a strange AOE disable in that it does no damage by itself.  It needs something to go with it.
This is similar to Enigma's Black Hole, except Overgrowth can't be interrupted.

Sand King - Epicenter
Leshrac - Pulse Nova, Edict
Gyro - Call Down
Kunkka - Ghost Ship
Earth Spirit - Magnetize
Venomancer - Poison Nova
Jakiro - Macropyre
Lich - Chain Frost
Undying - Tombstone (it's not an ult, but it's close)
