Mystic Mail is a Buffing Spell.
This spell grants the spellcaster the Mystic Mail Status Effect for a duration of 20 Status Ticks. While under the effect of Mystic Mail, the character is treated as though wearing armor that grants 6 soak against Piercing, Slashing, and Impact damage types. The spell can be stacked, increasing the duration of the effect.
Unlike the Mystic Shield spell, this spell does not stack with mundane soak granted by equipped armor.
