I don't have any friends with ADKs (used some other leaders with 2.5 or 3x bonuses across various conditions), and I also know nothing about awakening or skill ups. I do have a bazillion Tamadras and mats sitting around though, including a King Emerald. Maybe I'll look into that.
So you just need to feed one Tamadra into your ADK and he will get a new awaken called 'Two-Pronged Attack' which boosts damage and makes him attack 2 enemies instead of 1 when matching four orbs instead of 3. You can see all the awakenings in order (top to bottom) when in the top right of the monster portrait grayed out until you use Tamas.
Alternatively, you can feed another ADK into your ADK to activate it. But they're giving out Tamas like candy right now and you probably can't farm another one with the dungeon gone, so go nuts!
