Repair and Self-Repair

Build power decides how fast a builder builds, but it plays no part in repair. Every builder repairs at the same speed.

Repair

A builder repairing a finished unit restores 1 hit point every tick, which is 30 hit points a second. Each tick it also asks for 1 energy, so repair costs 30 energy a second and no metal.

• The rate is the same for every builder. The Commander, with a build power of 300, repairs no faster than a Construction Aircraft with 50.
• Several repairers add up: three builders restore 90 hit points a second.
• Each repairer pays its own energy. During an energy stall it stops until its debt is paid.
• Repair goes past armour and veterancy: every point counts in full, up to the unit's maximum.
• Repair pauses while the unit being repaired is moving.

An order to repair a unit that is not finished helps to build it instead, at the builder's build power.

Worked Example

A Bulldog has 2102 hit points. Brought back from half health, it needs 1051 hit points:

The energy cost is the same however many builders share the work. A Krogoth brought back from half of its 29,918 hit points takes one builder more than 8 minutes.

Self-Repair

Only the two Commanders repair themselves; no other unit in the game has a heal time in its data. Every 8 ticks a damaged Commander regains 1 hit point and asks for 1 energy, which comes to 3.75 hit points and 3.75 energy a second. Like any repair, it stops during an energy stall.

A Commander down to 1000 of its 3000 hit points needs almost 9 minutes and 2000 energy to repair itself fully. A single Construction KBot does the same work in 67 seconds.
