Evolutions

Evolutions are permanent upgrades purchased using DNA and survive through Tortoise Ascensions. Some Evolutions will appear to replace the same version of itself, but both evolutions' bonuses will be combined.

Evolutions for the War Tortoise become available for purchase as War Rank increases. Evolutions for units become available for purchase as the previous Evolution for that unit is purchased, with the exception of Prowess and Damage which are unlocked by War Rank.

Important evolutions to increase player progress are: Tortoise's Auto Battle (fire at enemies automatically) and Stamina (regenerate Energy), Mouse Miners' Digger (Increased change to find rare currency), Pack Mouse's Scavenger (chance to collect rare currency at the end of each level), and Heroes' Quest Efficiency (decrease quest time for Heroes and Pilots).
