Col
Col is the in-game currency of Echoes of Aincrad. It is the money players earn, spend, and trade across the first two floors of Aincrad, lifted directly from the Sword Art Online canon where Col is the standard currency of the MMO.
Uses
Col is spent on gear, upgrade materials, consumables, and anything merchants sell across Floor 1 - Town of Beginnings and Floor 2 - Urbus. It is the backbone of the player's economy, sitting alongside the Smithy system as the main way builds are shaped outside of combat.
Starter Grant
The Starter Pack, included with the Ultimate Edition, grants 50,000 Col at the start of the game, which is intended to give players room to experiment with loadouts instead of scrimping for early purchases.
