Grimrock

I dont think it recharges (i've already used all it's charges in a challenge... then gave it to my lizard rogue for safekeeping) good news is.. it doesnt just turns into a "dull old longsword" after the charges are spent... it still deals fire damage... but i've still yet to see if enemies are susceptible to specific kind of damage... not enough tests

Excellent. Thank you for helping me, Draken

note: it deals fire MELEE damage, as opposed to the fireball it shoots when charged. The same thing happens with a poisonous dagger you find a few levels before... forgot where.
