This blessing was created by Luca of House Rivers, the first and only animal known to possess the Ruinous Force. Luca used this ability to guard her new masters from attacks that may have proved fatal for them during certain times of weakness. Scientist to this day still wonder how a dog came into possession of Ruin... Some believe it was due to her proximity to Ezra that accounted for such a strange occurrence to happen.
When you use this Blessing, you create a thin barrier around yourself, allowing you to disregard instant death for a short period of time. Luca's Tenacity functions like the spell: Death Ward, except you can only target yourself and must wait 2d6 minutes before you may use it again
