Rune Magic

Rune Magic [General]

You have learned the ancient written magic of the dwarves.
Prerequisites: Spellcasting track
Benefit: As a standard action, if you do not already have an active spelltrap spread, or if you are 10th level or higher and have no more than one active spelltrap spread, you may spend a spell slot of any circle. If you do, choose a spell you know of that circle or lower. Make all decisions for that spell as if you had cast the spell, except if that spell targets one or more creatures or squares, do not decide its targets at this time. You create a 10 ft radius spelltrap spread originating from an adjacent square of your choice, which lasts and remains active until it is discharged. This counts as casting a spell for the purposes of provoking attacks of opportunity.

When an opponent begins its turn in or enters the spread, you may cast the chosen spell without provoking attacks of opportunity and without spending a spell slot as though you occupied a square of your choice in the spread, using the decisions you made for when you created the spread, and the spread is discharged. If that spell targets one or more creatures or squares, you decide its targets at this time, with the following exceptions: if the spell targets one or more creatures, you must choose that opponent as a target of the spell if able; and if the spell targets one or more squares, you must choose one square that opponent occupies as a target of the spell if able. This spread may be detected or disarmed as if it were a trap with an EL equal to your level.
