“ Moonlight shines down on the tranquil scene of a slumbering inn along one of the many roads that cross the land. Trees sway gently in the night air, and the stars twinkle brightly. All is quiet as the PCs snore away, a fine tendril of smoke curlsrnunder their door. The tavern is on fire! This is particularly bad news if the PCs own any horses - the screaming they hear is probably from their mounts! Panicky people are rushing about with buckets of water, trying to tame the flames. The fire fighting effort is not very coordinated as everybody is either hungover or still drunk, including the PCs. Hurry!”
“ Rather than making a baddy impossible to hit, consider giving it mega-hit points.
Super hard to hit leads to great player frustration. Allowing them to do damage leads to a sense of accomplishment. another variation of this would be to give the bad guy a forcefield that shows damage.You could also give them a mastermind ability that sluffs the damage of to minions who should be easy to kill.Once in a while a super high to hit encounter is ok ,but it should be few and far between.
Your mileage may vary”
“ A casual remark by one of the party about something met on a previous adventure leads to a summons to and grilling by the Mages' Guild (or equivalent), probably resulting in an expedition back to that area to recover the things for study by the Guild. The party's presence will be 'requested' for this expedition.”
