Pilots

What Are Pilots?
Pilots are units that you can purchase with Gems, and they each help you out in different ways. Pilots direct the turret on top of the War Tortoise, and they all do the same damage. All Pilots have a passive and active ability, and they keep their levels through War Tortoise Ascensions. Only one Pilot can be Active at a time.

Each Pilot
Here is the list of all the Pilots with their respective prices and abilities. The X and Y values increases with Pilot level, except for Butter's War Rank xp bonus, which decreases in the percentage of bonus xp received as Butter's level increases.

Leveling Up
Your pilot earns xp while they are in battle. Once they are ready to level up, you can tap the star icon that appears on the right of the battle screen to do so. You can also hit the level up button under their name.

A floating red "xp" text will hover over your Pilot if it is not gaining xp from the current level. Switch to a lower level Pilot or move to a higher level to continue gaining Pilot xp.

Veterancy
Veteran level is what it costs in Gems to increase the max level of the pilot. The pilot will not continue leveling up when it hits the level cap until after you upgrade its veterancy. Here is the stats for each level:

Mastery
When a Pilot's level is 600 and they have a Veterancy of 5, they become Mastered. Mastered Pilots' passive abilities are active all the time, even if the pilot themselves are not. Leveling a pilot from Veterancy 5 to 1A will not lose any Mastered abilities.

You can have all pilots mastered.

Some tips
Unlike Heroes, Pilots do not appear to receive a free trial. Pilots that are not active will go on quests to periodically earn rewards. Pilots on quests that have a red timer are on "cool-down" and will not return items until the timer turns blue again. Getting all of the pilots up to mastered really helps a lot!
