How to Grind for Col in Echoes of Aincrad

Summary.png

Read this guide to learn everything about Col, the in-game currency in Echoes of Aincrad. We listed the efficient ways to farm Col, and what it's used for.

Best Ways to Farm Col
1 Fight Bosses Repeatedly
2 Open Treasure Chests

Grinding Bosses Gets You the Most Col

Grinding Bosses

Bosses drop more Col than regular monsters you encounter while exploring, plus you'll build Weapon Proficiency while you're at it. Re-accept a quest you've already cleared and fight the boss if you're ever short of Col!

Open Chests and Explore, You'll Get Plenty of Col

Chests

Instead of grinding just for Col, you'll naturally collect plenty of it just by exploring and popping open Treasure Chests as you go. It's honestly one of the easiest ways to stay stocked up without extra effort.

Don't skip chests guarded by a challenge, like needing Ark Access, these often drop a Blueprint on top of the usual Col and items, making them well worth the detour as you progress the story.

Col is your go-to currency for purchasing consumables at the Item Seller, crafting, and upgrading gear at the Smithy. Some equipment can get pricey, so it helps to keep a solid Col reserve on hand.

Reallocating your stats at the Chest Orb also costs Col, and that cost climbs as your level increases. Double-check your balance before respeccing to make sure you can afford it.
