SPELL-DIVINE-WARD

Divine Ward calls upon the caster's diety to intervene in combat and protect them from all damage, making them temporarily invulnerable. Divine Ward confers 15 seconds of invulnerability to the person who casts it.

Divine Vigil is an upgrade to Divine Ward which confers 30 seconds of invulnerability.

Both of these spells use the Intervention rune, which can only be used once every other mud day (once per real life hour).
