Maybe different buttons for pick-up/drop and use? Also Ctrl-z first of all moves character, and only after opens spells tab, should be reassign i think.
Begin run with transformation from bloody altar and pet, build-in teleport spell already come in handy to escape stuck-situation with pet. Found funny bug - if order fetch when pet stands on same tile with anvil - you will open anvil tab remotely. It is impossible to buy equipment for pet because you can't make pet to step close to merchant where all brought equipments are dropped (while in Ж form).
There is no way to unequip your pet or look what it wears at the moment, right?
Tried to use bloody altar for second time in same run while carrying item for pet summoning, thought something interesting would happen, like evolution (like would add left claw as second weapon item and hard scales as second armor item ) or summoning strong pet, but got empty pouch and reset to my equipment to +0, well, i wanted to and i tried.
Spear spell doesn't work when there is only one enemy in sight i think, aim around the target doesn't appear and i don't see any effect if cast anyway. Also if try to cancel this spell while choosing "who to attack?" - your bar anyway will get blood drained for this action.
I can pick up magic scroll from a ground but only if on same tile lies something else, and if i very need that scroll i can undress in hope that one of my item will be dropped on that tile, and then i pick everything up (doesn't work with meat).
Tried to summon second pet while first is still alive, it worked!.. At first second... Well, the second pet was summoned but my old one (or new one? I couldn't tell) refused to obey my commands and just followed me until i entered next floor - then it disappeared.
Also, what does BLESSED and (M) tags on equipment means?
