The champion that promoted it will be granted any gold it may earn from kills.
On the Crystal Scar, Super minions are transformed into Anti-turret cannons.
The anti-turret cannon is very efficient in capturing neutral or enemy capture points, as they have a faster rate of capture and more health than regular minions. However, the anti-turret cannon will still die along with all other minions after capturing a point.
Casting Promote on a super minion will grant the following buffs:
Buffs attack speed ~80% (1.25 attacks per second from 0.694)
Adds (Champion level x 75) + 200 max health (except at level 3, where it adds +500), and healing it completely
