Strengthen Door

Sometimes, an enemy has to be hindered from passing a certain door. Since they are not above using violence to smash said doors in, the spell Strengthen Door allows the caster to repair doors and even make them stronger, to deny passage to hostiles. This makes the spell different from spells like Magic Lock.

Trivia

 * In terms of usefulness, the spell is completely useless, as open doors are to the player's advantage.
