Cast Changes

  1. Modifies Mend & Maim with: Mend & Maim Augment: 100% of charge is conserved when switching between forms.
  2. Rank up the augment to unlock the full effect values.
  3. Costs a mod slot (and capacity) — only equip it when the change matters for your loop.

Worth the Slot?

  1. Worth it when the augment’s change is central to how you play Equinox.
  2. Skip it if the base Mend & Maim already does what you need and you’d rather keep the slot for survivability or strength.

Tips & Tricks

  • Read the battlefield first — cast Mend & Maim when it actually solves the room, not on cooldown habit.
  • Pair Mend & Maim with movement and energy economy so you’re not stranded after a big spend.
  • On Steel Path, confirm whether Mend & Maim still carries without strip, Viral, or a squad buff.
  • If you never press 4, it’s the first Helminth candidate on Equinox.
