Note that the save DC for Kepé's breath weapon went down by one due to his reduced Constitution.
Kepé[sblock]Everything is correct, except that I think you have 3 level 5 slots left. You used two cloudkills against the nightmare beast. Did you use one earlier? You can use breath weapon again in round 106.[/sblock]
Frank does not feel like leaving (32 Will save). Also, Frank is not intimidated by Kepé's presence (32 Will save).
