Surge orbs in Abyssus are collectibles, not combat pickups. Breaking them unlocks suit color/customization rewards in the Nautical Wardrobe, and collecting all of them in a location can also count toward achievement progress.

What they do

  • They appear in fixed spots, not random ones.
  • They are tracked individually for each player, so in co-op everyone has to collect them separately.
  • They do not spawn in Elite or Boss rooms.

Rewards

  • Completing the Lobby set unlocks the Tinker suit color.
  • Completing biome sets unlocks additional suit material colors.

Quick scoop

Basically: shoot them for cosmetic unlocks, not power upgrades.

TL;DR: Surge orbs in Abyssus are fixed-location collectibles that unlock outfit colors and related completion rewards when you gather them all in a zone.
