Regenerate
(Rule)Description: At the end of each Tyranid turn, Old One Eye regains one lost wound, up to its maximum of 4. If Old One Eye is killed mark the spot where it died and then roll a D6 at the end of the next Tyranid turn. On a roll of 4 or more Old One Eye rears back to its feet with one wound and the model is returned to the tabletop. Move it into close combat if there is an enemy model with 3" of the marker.
