Power Cores
Power Cores are essential building block materials to upgrade your weapons and abilities. There are four types: Common, Uncommon, Rare, and Epic. Each one can either be crafted from materials (core residue, ability core fragments/shards/gems, weapon core fragments/shards/gems, crystal geodes, and living essence), found within any tier of dungeon, or combined from 5 of the previous tier of ability power cores.
Crafting & Combining
Head to Arcadia and enter Dr. Fritz's lab, the building most Southeast of the city. Click on the computer to begin crafting.
There are many options to make either weapon or ability power cores, but the upgrade the player is able to create will be highlighted. It is possible to combine the lesser materials into higher tier ones at this station, if needed. If combining power cores, the player will need 5 of the previous tier in order to make one of the desired tier (5 Common = 1 Uncommon, etc.).
When a player reaches the point of Epic power cores, the only place to craft these is at a Level 2 Manufacturing Table in a player-owned apartment.
Where to Find?
Weapon and Ability Power Cores can be found throughout the game. As you complete achievements, quests, and dungeons, the player will accumulate enough to upgrade abilities and weapons. Later on, there will be a quest for a vending machine in Virelda to acquire items for its stock. Once completed, the player will be able to buy core residue and ability power cores in limited supplies twice a day (every 12 hours) for gold.
Tip: It is recommended to try out abilities first before upgrading them so you do not waste valuable resources.
