acrobatics, history, intimidate
Acrobatics - Have your players ever made you have to quickly rework/improvise an entire adventure? - not really, but that has to do mostly with how i design campaigns; i have players make characters first with a loose knowledge of the world, and try to write major plot points around the characters, i really like the feeling of being a world changer even if you arent necessarily a major political player. The Fallout Effect (tm) where everyone just happens to be in the right place at the right time.
also i keep my writing very open in general, i have a few set pieces/ key plot points that i try to guide players toward, but leave it very open in between.
History - When did you first start tabletop gaming?- i think like 2 years ago now? i played a few one-off pathfinder sessions with friends in HS/ college but never really got into it. i started listening to TAZ and loved how freeform 5e is and decided i wanted to play, but couldnt find anyone to DM, so i bit the bullet and tried it myself! i was actually DMing for about a year before i ever got to actually play
Intimidate - Have you ever had to ban someone from your table?- no but i have come. Close. also ive threatened to give my players a prison tattoo of the attack roll formula in basically every game ive ever run
