Drone Combiner Station

The Drone Combiner Station is an interactable introduced in the Alloyed Collective update.

It allows you to combine 2 matching drones.

Combining Drones will:

• Combine their total health and damage (doubles with each tier).
• Reduce skill cooldowns by 20% per tier.
• Linearly increase a drone's skill-specific value.
  • Usually, this is a 50% bonus to projectiles/damage (combat drones) or effect duration (healing drones).
• Linearly increase the price by 20%.
  • Keep in mind that repairing drones only costs 66.6% of their base cost.

Tier	Drones used	Damage, healing & health	Skill cooldown	Effectiveness	Price multiplier	Size	Operator's Admin Override increase
1	1	100%	100%	1x	1x	100%	100%
2	2	200%	80%	2.5 - 3.75x	1.2x	100%	125%
3	4	400%	64%	4.7 - 12.5x	1.4x	150%	150%
4	8	800%	51.2%	7.8 - 39x	1.6x	180%	175%
5	16	1600%	40.96%	12.2 - 117.2x	1.8x	200%	200%

Rough effectiveness is largely capped by attack speed, whether skills have any cooldown to begin with, and if the drone makes use of its damage stat at all.

This makes Drone Combining massively beneficial, to the point where trying to get matching Drone Pairs (through Triple Drone Shops or cooperative multiplayer), just for combining, is a good idea.

Colors

Tiered drones change their colors and glow, similar to elite enemies. They also grow in size.

• 

  Tier 1
• 

  Tier 2
• 

  Tier 3
• 

  Tier 4

Starting with Tier 5, tier colors will repeat.

Notes

• Downsides of combining:
  • Empathy CoresEmpathy Cores
    Recruit a pair of Solus Probes that gain power with more allies.
    Every 30 seconds, summon two Solus Probes that gain +100% (+100% per stack) damage per ally on your team. will be less powerful after combining drones due to the presence of fewer allies.
  • Combined drones do not get multiple stacks of Defensive MicrobotsDefensive Microbots
    Shoot down nearby projectiles. Recharge rate scales with attack speed.
    Shoot down 1 (+1 per stack) projectiles within 20m every 0.5 seconds. Recharge rate scales with attack speed., therefore providing less defensive capabilities than what multiple lower-tier drones could.

Trivia

There is an unused Drone Upgrade Station in the game that uses the same model as the original.

• In exchange for an item, it would give that item to all of the owner's drones.
  • Any future drones obtained afterwards would not be given already exchanged items.
  • Drones would not get any items re-applied to themselves after being repaired.
