Green’s mace pattern
Mace Smack → Double Mace → Charge Poison. Smack lands after a side flip for 7 piercing damage. Double Mace hits twice for 3 each. Charge Poison enchants later hits; it is not itself a healing action.
Purple’s fast and delayed hits
Speedy Slash is immediate after the approach. Triple Slash starts with two quick hits, pauses, then ends with a third stab. Leave room in your timing for that final pause.
Use the train encounter’s ally
This is the Chapter 3 train fight, where Red n’ Blue assist. Track both enemies’ HP before choosing the next target: Revenge gives the survivor ATK Up. If one falls much earlier, you have to endure more turns of the buffed remaining enemy.
