All Present and Accounted For
Win a non-Puzzle Battle without any of your units being killed.

Was that supposed to hurt?
Win a non-Puzzle Battle with less than 10 damage taken in total.
Similar to All Present and Accounted For, there are battles early on with minimal damage, if the AI plays a card with a damage order, try to remove it quickly. Armour is also helpful.

Party's over!
Kill 9 enemies simultaneously.
In the first battle of the Aedirn map "Not a Living Soul" play a pitfall trap melee, then play a pitfall trap ranged. Once the AI has played two Alpha Wolves one will have 9 strength. Use the Rivian Broadsword on the 9 power wolf. When the AI has filled the melee row with 8 Nekkers, it will pass. Each Nekker has 5 power, use the Lyrian Horn and then the Rivian Broadsword to kill them and the 5 strength Alpha Wolf.
