I just realize how the teamwork worked here. it was a bit confusing at first
Noelle: Water Magic
Zora: Ash/trap magic
Naga nest: A barrier made of water. can be done in reverse to create an air bubble and fill surrounding with ater.
Water Dragon attack
Water armor. absolute mana control in said armor. can move in air?
Nozel is main attacker.
Nozel uses the Mercury to help move Noelle (same way string girl and teleporter move Asta).
Elves run into the trap Zora set ahead of time. (and Noelle avoid said magic using Coward relevation thanks Zora, which allows allies to see the traps Zora set).
This set opening for Nozel to move Noelle attack elves.
Nozel & Noelle attack elves and "Miss".
Actually the directed the attacks to the traps Zora set, which would reflect back to the elves at 2x the power.
