Katarina Bug

It was the last battle, in the end, the only champions that remained where a stacked Katarina with 0 mana (she had just ulted) with spell crit gauntlet and darkin, and a unstacked volibear.

We went to overtime, katarina was at 1 hit to die, my voli was at half health. Katarina atacked once, only once, and ulted instaltly.

The other player had 4 demons, meaning it was imposible for her, even triggering the demon trait, to refill her mana bar from only one hit, and it wasnt my voli hitting her because if he had hitted her, she would have died.
