"Gain Col. Droneman. Drones gain +25% (+25% per stack) attack speed and cooldown reduction. Drones gain 10% chance to fire a missile on hit, dealing 150% TOTAL damage. Drones gain an automatic chain gun that deals 6x50% damage, bouncing to 2 enemies." SotV DLC. Nerfed 50% by Alloyed Collective update. Affects all mechanical allies. Pocket ICBM does NOT affect the drone missiles. Does not give Col. Droneman to Engineer.
All Spare Drone Parts values were halved in the Alloyed Collective update. Attack speed: 50% to 25%. Cooldown reduction: 50% to 25%. Missile damage: 300% to 150%. Chain gun: 6x100% to 6x50%. Developer note: "With the new drones, increased drone acquisition and new drone AI in DLC3, SDP would essentially play the game for you." It is still considered one of the strongest red items in the game.
Col. Droneman receives all Spare Drone Parts buffs himself - he fires the chain gun and missiles like any other affected drone. He also respawns at stage start, making him a reliable long-term ally. Does not spawn for Engineer. Artifact of Swarms doubles him to two Dronemen at half HP.
Spare Drone Parts gives all your mechanical allies (drones, Engineer turrets, etc.) +25% attack speed and -25% cooldown reduction per stack, a 10% chance per hit to fire a missile for 150% TOTAL damage, and a chain gun that fires 6 shots at 50% damage each bouncing to 2 enemies. You also gain Col. Droneman as a permanent ally who respawns every stage.
Yes. The Alloyed Collective DLC (DLC3) reduced all Spare Drone Parts values by 50%. Attack speed went from +50% to +25% per stack, cooldown reduction from -50% to -25%, missile damage from 300% to 150%, and chain gun from 6x100% to 6x50%. The developer note stated that with improved drone AI and more drones available in DLC3, the original values would "essentially play the game for you."
Yes. Engineer turrets are mechanical allies and receive all Spare Drone Parts buffs - increased attack speed, cooldown reduction, chain gun, and missile procs. However, Engineer turrets do NOT get their own Col. Droneman. The combination of Engineer's inherited items + Spare Drone Parts attack speed is one of the most powerful setups in the game.
No. The missiles fired by drones through Spare Drone Parts are specifically excluded from Pocket ICBM's tripling effect. This is an explicit exception in the game code. Your other missile items (AtG Missiles, Disposable Missile Launcher) still benefit from Pocket ICBM normally.
Col. Droneman is a permanent drone ally granted by Spare Drone Parts with 180 HP (+54 per level) and 12 base damage (+2.4 per level). He respawns at the start of each stage if destroyed. Col. Droneman also benefits from all Spare Drone Parts buffs himself. He does not spawn for Engineer.
No. Despite looking mechanical, Squid Turrets (from Squid Polyp) and Alpha Constructs (from Defense Nucleus) are not classified as mechanical allies in the game code and do not receive Spare Drone Parts buffs. Only drones and Engineer turrets (and similar mechanical entities) are affected.
