A new Combat Lab upgrade has been released allowing you to now upgrade the building to level 20. These new upgrade levels mean it is now possible to enhance your cores sets, meaning you can add further stats to the newly released Supreme Destruction set.
At level 20 you are able to boost core sets by a total of 1400% Troop Attack for all 7 pieces combined. This is a Substantial increase to the attack stat and will make the core sets much stronger.
These new upgrade levels also provide further Enhancement Efficiency (12% at level 20 up from 9% at level 15) which will reduced the Spare part and Key Component costs when enhancing Gear.
There is no increase in the level that regular Gear can be enhanced to, that remains the same as before: level 10 at Combat Lab 15
