Illaoi E - R synergy for viability in higher ELOs
I quite like Illaoi's kit, it feels fun to play and has some clear strengths and weaknesses. The problem is lategame it's a bit too easy to exploit the weaknesses.
I think E - Test of Spirit and _R - Leap of Faith _should have the following synergy:
If Leap of Faith hits a spirit instead of an enemy champion the idol slams at the tethered champions location instead.
This would allow Illaoi to be a greater threat to the backline. It would also have some counterplay since even if a squishy gets E'd and kites away a tank can stand next to the spirit to prevent the R transfer (similar to bodyblocking blocking a thresh lantern).
Since it's clearly a lategame buff I think a small tweak to E would be handy to offset that. Instead of relying on tentacle takedown mechanics I think E's debuff should drop if 3 tentacles dare destroyed in your vicinity, without you having to actually hit them.
