Yeah I would say just try to pick the lock, if you're worried about having to fight a mimic take a warp scroll/cudgel with you and try to have it ready before picking a coffer or have another peep with you. I never even got my AF body or feet, kinda regret not getting the feet as the 15 sec of flee would be nice at times but only means i would have one more piece of gear to carry with me for macro use only
I second this suggestion, all of my THF AF pieces were picked open. Ran into a couple mimics doing that, but as stated that's what the scrolls 'o warp are there for.
Onto topic, recently I was farming Ahriman in Castle Z. and my bloody bolts werent proccing very often either, I mostly relied on my NPC for healing or just taking a break between series of fights to /heal.
If you're paranoid about that situation happening again (the -ga spell to wipe shadows then sleepga followed by an AM) carry some sleep bolts if you arent saving TP for the sole pupose of interrupting spells, and pray that you not only hit but that it procs (if Airy Shield is up, dont bother trying to hit w/ sleep bolt). Also what you may try if you're slept, take off all evasion+ pieces and hope that it hits you. (Sadly, Thief doesn't have much gear that is negative evasion)
