- Targets that fail to resist take 3 points of poison damage per second for 30 seconds.
Poison Rune is an adept level Restoration spell that creates a rune which will explode when enemies come near, causing them to take 3 damage per second for 30 seconds. When you press the cast button, the cross-hair will let you know if you are pointing at a valid surface within range. If it is red, then you can't cast the spell there.
- You can set off poison runes (your own or others) using any Restoration projectile spell from a distance.
- Some enemies are immune to this spell, notably all dragons, undead, Daedra, automata, and summoned or reanimated enemies of any kind. Note that though they may not be poisoned, they will still set off the rune if they touch it.
- The poison effects stack if the target is hit by a second poison rune before the effects of the first rune wears off.
