Energy and Runes

Energy System

Each Catto NFT has an energy capacity, which allows for runes to be socketed to the Catto. As a user gains EXP and levels up their NFTs, the energy capacity of the Catto will grow. Catto NFTs can only hold as many runes as their energy capacity allows for.

Level	Tier 1 Energy Capacity	Tier 2 Energy Capacity	Tier 3 Energy Capacity
0-5	0	2	4
6-10	2	4	6
11-15	3	5	7
16-20	4	6	8
21-25	5	7	9
26-30	6	8	10
31-35	7	9	11
36-40	8	10	12
41-45	9	11	13
46-50	10	12	14
