Spell modifiers that cause projectiles to transmute nearby materials.
Lava To Blood is a projectile modifierspell that causes affected projectiles to transmute lava into blood in a moderate radius around them as they travel.
Tips
This spell can be useful to have on a primary combat wand since it will safely transmute otherwise dangerous lava bled by certain enemies.
An especially beneficial property of using Lava to Blood for digging is that unlike most rock types made when solidifying lava, volcanic rock created from blood does not melt from lava.
The above usage pairs well with the Vampirism perk, particularly in the latter case.
