Short answer: The base Cobblemon mod doesn't include Mega Evolution. It's added by addons that servers and modpacks install. On Complex Cobblemon (cobblemon.mc-complex.com), every Mega Evolution from the Pokemon games is in. To Mega Evolve, you need a Key Stone (Mega Ring), which you can earn from world boss raids every 3 hours, and the right Mega Stone held by your Pokemon. Then choose the Mega Evolution option in the battle menu. It works in every battle.⚡ Quick facts

Mega Stones: drops from the evolution line, the Dungeons shop and trading
