Medi-Ray

Sentinel mod that periodically heals its owner

Released Apr 29, 2016

Medi-Ray lets a Sentinel occasionally restore the owner's Health over four seconds. Consider it as periodic healing support on a robotic companion; it does not provide an always-on heal.

Medi-Ray GUIDE

Understand Medi-Ray

Useful when…

  • Adding occasional owner Health restoration to a Sentinel setup.

Heal and trigger behavior

At maximum rank, Medi-Ray occasionally restores 12% Health over 4 seconds; rank 0 restores 2% over the same duration. The description says the Sentinel heals its owner occasionally, so treat this as periodic support rather than continuous regeneration or an on-demand heal.

Fit and rank

Medi-Ray is a standard Robotic mod with Penjaga polarity, base drain 0, and maximum rank 5. The listed costs rise from 20 Endo/966 Credits for rank 0 to 1, to 80/3,864 for rank 2 to 3, and 320/15,456 for rank 4 to 5. Ranking increases the restored percentage while keeping the listed four-second duration.

Other robotic support effects

Guardian instead boosts the owner's shield by 100% when it runs out, while Sanctuary creates a 1,800 Health shield around the player when reviving fallen allies. Anti-Grav Array increases jump height by 40%. These have distinct triggers or movement utility and do not duplicate Medi-Ray's occasional Health restoration.

Acquisition

The supplied acquisition entry names Kela De Thaym as a source.

Limitations and tradeoffs

  • Healing occurs occasionally, not on demand.
  • The effect requires the mod to be used on compatible Robotic equipment.

Common mistakes to avoid

  • Expecting Medi-Ray to heal continuously or when manually activated.
  • Confusing its owner Health restoration with shield recovery.
  • Treating the comparison mods' different triggers as equivalent healing effects.
