[Moku203]

As of the recent update it seems placing elemental runes no longer uses any tome damage, just the default of fire, though it still uses the tome damage when engraving it onto another tile with a mob in it.


Steps to reproduce:

Equip a tome (Cartblanche in my case)
engrave elemental rune, it will do tome damage.
lay down the rune in the field, it will be fire elemental, and thus less damage if you're not built for fire.
