Frost Rune is an Apprentice Destruction spell that sets a trap of ice. The caster places a glowing rune on the ground or a wall. When an enemy comes near, the rune explodes for 50 points of frost damage. Fire Rune and Lightning Rune are its partners in the other two elements.

Frost Rune is an early game spell, open once Destruction reaches the Apprentice rank. Faralda at the College of Winterhold and most court wizards sell the tome.

Spell Tome

Frost Rune is learned by reading Spell Tome: Frost Rune. Calcelmo, Enthir, Falion, Faralda, Farengar Secret-Fire, Madena, Sybille Stentor, Wuunferth the Unliving, Wylandriah and Talvas Fathryon sell the tome.

How It Plays

Frost Rune takes about a second to charge. The crosshair shows whether the chosen spot is a valid surface within range. The rune then sticks to the floor or wall as a glowing circle. When an enemy walks close, it bursts in a blast of cold.

The blast hurts health and stamina together. It also slows the enemies it catches. A warrior who runs through a Frost Rune arrives slower and with less stamina for power attacks. That makes the rune a good trap to lay in the path of a charging group.

A rune deals more damage than most early spells. Its 50 points beat the 40 points of Ice Storm, though Frost Rune is only an Apprentice spell. Another Destruction spell can set off the rune from a distance, so it also works as a delayed bomb.

Uses in Dungeons

Runes are ideal openers for a stealthy mage. A rune laid on a patrol path or in a doorway hits the first enemy who walks by. The slow effect then gives the caster time to follow up with spells or arrows.

Runes also help in Nordic barrows. A draugr resting in a wall niche or a coffin still sets off a rune placed close by. This wakes the draugr one at a time, and the rune hurts each one before it can climb out.

Frost has many resistant foes. Nords and vampires resist frost, and Frost Atronachs ignore it. Fire Rune or Lightning Rune is the better trap against those enemies.

Perks and Builds

The Apprentice Destruction perk halves the cost of Frost Rune. The Rune Master perk lets the caster place runes five times farther away, so a rune can land right under a distant enemy. Dual casting overcharges the rune for a much bigger blast.

Runes are a fast way to train Destruction. Each enemy caught in the blast gives experience, so a rune that hits several enemies gives several times as much.

Early and Late Game

Frost Rune is at its strongest early on. An Apprentice caster gets a blast stronger than Ice Storm long before the Adept rank. The rune costs 293 magicka at a skill of zero, so the Apprentice Destruction perk and cost reducing robes make a big difference.

The rune falls behind later in the game. The Augmented Frost perk passes it by, while the other frost spells gain up to half again in damage from it. By the late game, the rune works best as a trap or an opener rather than as a main attack. A stealthy character who has time to set the trap can still use it to great effect.

Placing Runes

A rune can only be placed within about 20 feet of the caster. The Rune Master perk raises that reach to 100 feet. With the perk, a rune can be dropped right at the feet of a distant enemy for an instant blast.

The Quiet Casting perk in Illusion makes every spell silent to others, runes included. A sneaking mage can then lay a trap close to enemies without giving away the hiding spot. Frost Rune pairs well with a bow, since a slowed target is easy to hit with arrows.

Frost Rune tomes also turn up as loot in chests and on the bodies of mages and draugr.
