Zagreus bots move quickly, cannot be seen by radar, and are the most cost-efficient source of mobile buildpower in the game—though they can only repair, reclaim and resurrect, not assist other constructions. Their most notable ability is "Resurrecting" dead units, which brings the unit back to life at 1 HP, then queues the resurrector(s) to Repair that unit to full health.

Resurrected units lose all the experience & levels they had while alive.

Resurrection requires 50% of the original unit's total energy cost. Only intact wrecks can be resurrected; if a wreck takes enough damage, it will become a heap of debris that can only be Reclaimed.

Resurrection bots are a critical part of Bots' early game tactics. Keep them alive and they will keep your army alive.
