Unit above level 130 can upgrade its C.A.P.(Crystal Amplified Potency), which means that all unit's attributes will be strengthened, such as HP, attack, defense, or even the size of your cabin. Every time you upgrade the CAP, your unit's potency will be increased by 1.

How to Upgrade
Talk to the CAP Technician (450,756) on the Steel Warship.

Put in your unit.

If your unit can't meet the requirements, the CAP Analysis will show you in red.

If the unit can meet the requirements, click OK to proceed.

After the CAP is upgraded, the CAP Analysis will show you the promoted attributes.

Requirements:

Currently, the highest CAP is 90 stars. Before 70 stars, you can directly upgrade it with the help of CAP Technician. But from 71 stars to 90 stars, you have to swap 2 CAP Items from the R & D center and take them to CAP Technician to upgrade your CAP.

For a unit whose CAP is higher than 20 stars, everytime when the CAP is upgraded, the unit will be in the cooling status for 2 hours.
