In your Command phase, each HARVESTER unit from your army can Regenerate one friendly TYRANIDS unit that is within 6" of it. A unit can only be regenerated once per phase. Each time a unit regenerates, do one of the following:
◦One model in that unit regains up to D3+1 lost wounds.
◦One destroyed INFANTRY model (excluding CHARACTERS) is returned to that unit with its full wounds remaining. If that unit is an ENDLESS MULTITUDE unit, up to 3 destroyed models are returned instead.
