Not many people know about this, but in Morrowind you can hit an incoming spell projectile with another spell projectile or arrow/bolt/throwing weapons in mid-air and they will cancel each other.
- Enemy cast a target spell
- You throw a weapon/fire an arrow/cast a targeted spell to the flying projectile
- If it hits, the projectiles ends mid-air.
What works versus spell projectiles:
- Throwing weapons
- Cast on target spells
- Cast on target items
OpenMW has not yet implemented this.
