I used HP, SP, and defence scrolls.
Removing my weapon didn't work for some reason o-o I'm glad I got my weapon back on before I was weaponless without it >.<
I remember coming out of that trial with no pots and stones left but 1 SP stone left ... I had no idea that I was going to spend all those stuff in it, LOL. Went in with like 10 HP and SP stones each and a few tier 1 pots.
