Found 2 glitched interactions on mobile. If you are 1 tooth from winning and you use pliers, then it won't end the phase. (Don't know about other bosses and regular battles) It only ends AFTER you end your turn (when we played, we had to place a card that attacked then press the bell to end turn then we won the phase.
Secondly. Giving dire wolf pup the bifurcatcation sigil (don't know if giving both bifurcation and movement sigil caused the glitch) will cause the pup to work normally HOWEVER when it upgrades into a dire wolf, the double strike sigil loses its property to attack twice infront of it.
