Do Temper/Haste/Nul spells stack?
Haste/FAST doesn’t stack. Temper/Steel does stack. The Nul spells do stack with each other, but not themselves. In other words, you can cast NulBlaze, NulShock, and NulFrost together, but casting NulBlaze over and over doesn’t do any good. Also, armor with elemental resistance makes these spells obsolete. If everyone is wearing a Ribbon, you never need to cast them again.
