Yesterday I was playing Tryndamere top. We had a large advantage and managed to destroy everything up to the nexus tower. During the final minutes of the game I decided to fountain dive the enemy Lux that just respawned but despite activating my ultimate, I died really quickly.
Isn't Tryndamere's ultimate called Undying Rage?
In the wiki it says: Tryndamere becomes completely immune to death for 5 seconds, refusing to be reduced below 30/50/70 Health and instantly gaining 50/75/100 Fury.
So why did I die in the fountain? Shouldn't I be unkillable for 5 seconds?
