Drones: levels, stars and skills

A drone flies over your tank, boosts its stats and acts on its own. The game only shows the level you are on and the price of the next: here is what players recorded, drone by drone.

How it works

Getting a drone
With beacons: they refresh the selection or buy one of the three drones on offer. The shop’s Drone Pack gives one too.
Levelling up
In microchips. Each level raises the attack, health and defence bonus by the same step. Step and price depend on rarity: an SSR starts at +12% and gains 0.3% per level, where a green-frame drone starts at +4% and gains 0.1%.
Earning stars
By fusing copies of the same drone. Stars do not change the bonus: they unlock the skills and their tiers.
Starting over
The Reset button refunds every microchip invested: you can switch drones without losing anything.
Equipping
One active drone at a time. The others wait in the collection.

Summoning: price by rarity

The summon screen offers three drones at a time, each bought with beacons at the price of its rarity. Refreshing the selection costs 10 beacons, 4 refreshes a day are free against an ad, and after 20 refreshes a UR drone is guaranteed among the offers.

Names and figures taken from the English version of the game. The French translation shows, for instance, 0.4% instead of 40% on Overcharge: a display error, not a different value.

The UR drones below were read on the summon screen, which only shows the first tier of each skill and the star that unlocks it. Later tiers and level prices remain to be recorded.
