Notes
With all perks unlocked, this is by far the most powerful damaging spell in the game, dealing more than five times as much damage as an adept level Fireball or Chain Lightning in the base game for roughly the same cost, more than three times as much damage as an expert level Incinerate or Thunderbolt in the base game for half the cost, and ignoring fire resistance (see Bugs).
Elemental Blast 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. Intense Flames does apply to the entire explosion.
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.
This spell has a base damage of 80 (per hand) (40 magic/40 shock) and is multiplicatively increased by augmented flames (50%) augmented frost (50%) and augmented shock (50%) for a total of 270 damage. (135 magic/135 shock) This is further increased by the aspect of terror perk which has an unusual interaction with this spell differing from how it affects other fire spells. It increases the spells damage by (10*1.5*1.5*1.5) (each 1.5* is from each of the augmentation perks) which is rounded to 33 increased damage for both the magic and shock parts of this spell increasing the total damage to 336. (168 magic/168 shock) The additional damage gained from aspect of terror is not increased to (15*1.5*1.5*1.5) even if the augmentation perks are taken first, the way usual fire spells are affected. Finally any of the 3 masks that increase either shock, frost or fire damage from the db dlc will increase the displayed damage by a flat 25%. Any of these masks increases the damage because this spell is flagged as a "magic" damage spell, so any of them increase the damage by that amount. This increases the total damage to 420. (210 magic/ 210 shock) This spells damage is also increased by the dual casting perk as most spells resulting in a dual cast of (420*2.2) 924 total damage. The most difficult part of these tests was figuring out the burn damage. The burn damage appears to be similar to all fire spells in that it is 20% of the initial damage. However, the initial damage that is used in calculation is only the "magic" damage component of the spell resulting in 20% of half of the spells damage, in other words, 10%. This causes the grand total of the spell to reach 1,016 damage, including the burn affect, when dual cast. The last component of damage is the disintegrate damage (assuming you have the perk) that will cause an additional 300 damage per spell whenever the target is at 15% max hp or lower. In any case, the maximum damage is 1,016.
