Personally, I am a circumstance modifying fiend!
I am always giving a bonus or penalty here and there for all sorts of conditions, or just little rare "common sense" things that the rules don't specifically cover.
Okay, I shouldn't say "always", but every few sessions something comes up and I never hesitate to make an ad hoc ruling about much more easy or difficult something is.
I might give a circumstance penalty to a Reflex save if made on the edge of a cliff.
I might give a circumstance penalty for a grapple check if you just climbed out of a mud bog (on the flip side I might give a bonus to your escape artist check if you are greased up like that).
I might give a circumstance bonus to some skill check if the player is clever/creative in describing how they use it - or has access to some normally unavailable resource to complete the task at hand.
I might give a circumstance penalty for a bluff check for a child lying to a parent (they always know
), or a one-time bonus for that same parent to attack someone harming their children.
Etc. . .Etc. . .
How often do you apply ad hoc circumstance modifiers as a DM? What are some examples? How do your players react to them?
