Evolution

Evolution is a system that applies changes towards a Mercenary or Gear through multiple stages (either 2 or 3), improving their performance, adding new visual effects and changing the weapon look for Mercenaries.

In order to evolve a Mercenary or a Gear, Soul Stones are required to ascend the next stage. The number of Soul Stones required for a singular Evolution stage is 2 for Gears (both Rare and Mercenary Weapons) and 5 for Mercenaries.
