Master Rune of Destruction

Alteration
Tier: 3
Components: Rune
Casting Time: 1 minute
Range: Touch
Target: Object or surface bearing the rune
Duration: Instantaneous
Saving Throw: Spell negates (object)
Cracks spread outward from the rune, and around them the wall turns to fine ash.

When wakened, this rune instantly cracks, splinters, corrodes, or otherwise deals major damage to the object on which it was scribed. Then, over the course of about a second, the seriously damaged material dissolves into ash. It only affects material within about 2.5 ft.

Sturdier materials are still more resistant, so this spell will create a smaller breach in a wall of iron than in a wall of stone.

Runic Power:
The rune affects material within 5 ft.
