SSR Baal : Thunder Lance Velyagloush : Pride++ & Ascension
Great self sustaining attacker with thunder down debuff

Athena : Sacred Lance Aegis : Defender++ & Assault
Niche tank that laughs at Water & single target attacks

As for non lance giving characters
Raiko is a great all rounder, Atk down, 45% team shield, 30 burst for entire team at cost of 12% health ( but you have Dian to counter this)

Tyr is also great fun, with her awakened buff a few months ago she can hit for 2.5m burst.
