I just encountered what might be a bug, but I'm not even cerain
What I think was a Samurai failed to execute my fron creature, instead only dealing a lot of damage
The creature was a level 3 Druid (the one that buffs by +5/+5 when damaged) and had been buffed both by itself and by shop effects ( creatures that buff when brought and sold). As a result the druid had over 70 hp
Don't think it affected the result of the fight thou, so no need to worry about that
