The King fight is easier if you back out of the room, in fact the "character" that starts all those encounters for me is a fire elemental.
basically this
the fight if you step in normally is quite hard for the starting aoe that halves your party
whatever trick you do makes the fight pretty easy, you just have to find a way to a void the starting aoe
this is another ai problem, ai cant really make a good use of spells, even if they have good ones
