Notes
This is a very powerful apprentice level spell. It starts out dealing equivalent damage to an adept level Fireball or Chain Lightning in the base game but costs roughly half as much, comes with an additional 15 damage shock hazard, and is much harder to resist (see Bugs). The damage per shot can easily surpass any spell in the base game with some perk investment. Using the calculation on the Elemental Burst page, it maxes out at 608 damage, which is significantly more than even the master spell Fire Storm.
Elemental Bolt will damage both friend or foe in its area of effect, although, it will not damage the caster. With this in mind, take care when using the spell in the company of followers who tend to fight at close range, as even protected NPCs can be killed in this manner.
For Deep Freeze Paralyze, Disintegrate, and Perk Impact Stagger to take effect, the spell projectile must hit the target, not just the explosion alone.
It is sometimes recommended to aim at a target's feet, instead of their body, so that dealing damage from the explosion effect is almost guaranteed. This also avoids the situation of missing a direct hit and dealing no damage whatsoever.
Like most Destruction spells, it can be used to detonate runes or oil slicks from a safe distance. Also, casting the spell, or merely having it ready to cast in an area with flammable gas will result in the ignition of the gas and a subsequent explosion.
This spell also appeared in the Spell Tomes official add-on for The Elder Scrolls IV: Oblivion.
