Dead pool dungeon and insta kill

[vadimkz]

Hello everyone. We play munchkin with many additional parts. My question is about the chrismas lite and demented dungeons (6th) addons.
For example we play with a dead pool dungeon (you have to roll a die at the start of the fight and open as many door cards as the die shows). I halfling and take the open door behind which is The Mighty Germ. Following the description I kill him instantly. In another situation I am Nice (from Chrismas lite). I openly take the Krampus card (chrismas lite) in the description of which it is said that Nice kills him instantly .
Both situations happened in our games.
Do I need to roll the dice in this case, following the Dead Pool dungeon rule ??
Does it mean instant win at level 9?

OP, no you would not re-roll the dice just because you insta-killed a monster. Like the card says, you only reroll if the person in combat asks for help and someone agrees.
