Is Undine Worth Using?
Essential. Undine has the best stun in the game — a B-rank Undine outperforms an A-rank Tidevex in real fights. It anchors every serious endgame team.
Team synergy: 2x Eclipse Knight + Undine is the endgame gold standard. Undine's stun interrupts dangerous boss attacks and the Spire spam attacks.
Alternatives: Kitsunine (stun + DPS hybrid), Mountusk, Tidevex (water tank)
