Warpflame
(Rule)Description: At the end of the phase, any unit that suffered one or more unsaved Wounds during the phase from an attack with this special rule must take a Toughness test. If the test is failed, the unit immediately suffers D3 Wounds with no armour or cover saves allowed. If the test is passed, all models in that unit gain the Feel No Pain (6+) special rule for the rest of the game. Any models that already have the Feel No Pain special rule instead gain +1 to all Feel No Pain rolls for the rest of the game.
