Fighting the Awakened one, ended turn with spiked shell at 231 damage with an empty hand while he was at 0 hp (due to the stall between his phase 1 and 2), right after I pressed end turn and before the spiked shell procced.

Game just up and crashed.

Also when spiked shell reached to the millions, game kept lagging every time it tried to calculate the new value.
(Damage was past 1k anyway can just cap it there).
Then the relic just up and broke and when I ended my turn it dealt 0 damage.
