A within reason nerf to Illaoi's "mini game"
Test of spirit creates a Spirit for 6/7/8/9/10 seconds down from 10 seconds at all ranks. Damaging Illaoi still reduces the duration by 1 second.
If it needs a buff against ranged after such a change make it so that damaging Illaoi with a ranged auto attack only reduces it by half a second.
If you are going to make a mini game riot at least make it so it is not mandatory suicide when you are forced to play it. Make there be some way to not completely lose if you go about it right.
