Last Chance will not activate if a race has resurrection effects that requires them to be at 0 HP.

The skill description does clearly mention that "upon taking damage that would leave you at 0 HP, you ignore it and remain at 1 HP", but From The Ashes and Formidable both ignore that, activating before Last Chance has a say on it.

This can likely be fixed by increasing Last Chance's priority over other effects, like I mentioned in the post I deleted since the info was wrong in it (many thanks to Autumn for help-), it could help if you flagged those effects as "Deathblow Denial" (Last Chance) and "Resurrection" (Everything else), so they know where they should stand in the pecking order. Might future proof it too.
