For 2 XP □ Pry Bar + □ Detachable combo is a bargain. I rarely get to use my Pocket Multi Tool in my own turn anymore since everyone else wants to take the pry bar to fix their problem in the Mythos Phase. +2 is the magic number.
Even after all had survived the Mythos Phase without exhausting my Pocket Multi Tool, "skill test on a treachery" still includes threat area treachery like a Forced check on Frozen in Fear. Some that required an just to try a test has synergy with □ Detachable since anyone could try anyone else's threat area with their own stat and take the pry bar adding to it, giving more turn order flexibility. My party is prying everything with this dang bar, from defending against lightning strike to prying evil spirit away from possessing my partner. Supposed if pry bar has one more □ like the other +1 customs I still wouldn't complain.
