Cast Changes
- Modifies Peacemaker with: Peacemaker Augment: Mesa can move at 50% Speed while using Peacemaker.
- Rank up the augment to unlock the full effect values.
- Costs a mod slot (and capacity) — only equip it when the change matters for your loop.
Worth the Slot?
- Worth it when the augment’s change is central to how you play Mesa.
- Skip it if the base Peacemaker already does what you need and you’d rather keep the slot for survivability or strength.
Tips & Tricks
- Read the battlefield first — cast Peacemaker when it actually solves the room, not on cooldown habit.
- Pair Peacemaker with movement and energy economy so you’re not stranded after a big spend.
- On Steel Path, confirm whether Peacemaker still carries without strip, Viral, or a squad buff.
- If you never press 4, it’s the first Helminth candidate on Mesa.

Mod Scaling
Strength
- Strength matters if Peacemaker scales effect power; otherwise dump it for other stats.
Duration
- Duration is low priority on Peacemaker unless an augment or lingering effect needs it.
Range
- Range is usually dumpable on Peacemaker unless you feel the hitbox is too tight.
Efficiency
- Peacemaker costs energy each cast — Efficiency (or strong regen) keeps the loop comfortable on long missions.
Priority
Stack the stats that actually move this ability’s needle, then Efficiency for uptime.
Mission Use Cases
| Mission | How to Use It |
|---|---|
| Steel Path Survival / Defense / Disruption | Test whether Peacemaker still clears or enables clear when enemies are dense and overlevelled. |
| Mobile Defense / Excavation | Use Peacemaker to control or delete the swarm on the objective, then reposition. |
| Exterminate / Capture Speed Runs | Cast Peacemaker only when it saves time — skip it on empty tiles. |
| Spy / Rescue / Quiet Routes | If Peacemaker is loud or forces combat, save it for after the vault; if it’s stealth-friendly, use it to stay safe. |
