same as what umchyoka said...except for 1 thing. if you're looking to go more towards a consumables build, then keeping the seasonings might still be worth...but it looks like you're in a more mage position so searching for a tome, a rage ring, a broken armor ring, and maybe a regen wand and skull wand would probably be what I would aim more for.
Either way, start replacing those health rings asap...they can be a helpful boost at early floors, but seeing as you're now at floor 13 they're practically useless...
