the list. Son of a Witch (Europe) (Switch) patch notes
4.1.0 (12 April 2019)
Heroes get HP increase when they die in RPG mode. Looking at players playing on Twitch, I discovered that players do have enough damage in RPG mode, but being able to survive long enough posed a challenge. So this change balances that out.
Vampire Slayer NPC, Alchemist's Golem, Skeleton Ranger NPC and Baby Yeti Familiar would try to attack enemies in a different room if you escaped a room before the battle is over, for example by using a bomb, teleport scroll, silver coin or escape scroll. This is now fixed and they retarget to enemies in the current room where the leading hero is.
Concealed characters (Rogue and heroes using Rogue Sword) are now visible during cut-scenes.
Alchemist can summon Golem to fight other players in PvP game.
Earthquake staff magic knocks down other players in PvP game.
Updated French and Russian translation.
