Improve how corpses and spectres works.

Considering the rarity of the corpses, it's unbelievable that whoever developed and approved this thought it would be a good idea.

30D+ for some corpses and a single gem swap with a trigger weapon+offering and the corpse is gone. Not to mention when it just disappears instead of dropping to the ground.

Some kind of "lock" on the gem or equip slot would solve this dumb interaction, or at least it should be in desecrate pool after using the corpse.
