Thief stone adds spell crit when you first get it, then when you change zones it goes away. I've been waiting a month for them to fix this stone for spells, and it's still broken. PLEASE hotfix this and the memory leak problem so we don't have to wait another month....
The weapon crit stays when you change zones, but the spell disappears from the stat sheet. I tested to see if it was somehow just a display error, but nope, doesn't work.
