DESCRIPTION

This spell affects a portal or opening within your stronghold as arcane lock, but it additionally creates a magical trap on it. If the secure seal is forced open by any means, it explodes in a 20- foot radius burst, dealing 1d4 points of force damage per caster level (maximum 10d4). This burst does not harm the walls, floor, windows, or any other permanent furnishings or features of your stronghold. Spell resistance applies against this damage, and a Reflex save is allowed for half damage. The secure seal can be detected as a magical trap with a DC 29 Perception check, and a successful DC 29 Disable Device check suppresses its explosive burst feature for 10 minutes. After a secure seal explodes, the spell ends. You can freely pass through your own secure seal without triggering its explosion.

You can cast this spell outside your stronghold, but its duration is reduced to 1 day per caster level.

* Stronghold Spells

As an optional rule, many of the spells designed to defend a stronghold below may be ruled to function only in an area that is a fixed point of defense called your stronghold. For the purpose of a stronghold spell, your stronghold must be a specific location or structure you designate, no larger than a cube 30 feet per level on a side. If this covers only part of a larger structure or location, you may use stronghold spells only within the designated area. You must spend at least seven days focusing on your stronghold, meditating upon its every detail, placing magical marks that resonate with your personal magic.

You may have only one stronghold at a time. If you create and designate a new one, the benefits of the old one fade immediately. Your death does not alter your stronghold, and stronghold spells persist after your death to the extent of their normal duration.
