Direct answer
Castella is a researched frontline and combo-finisher hero associated with Break, Stun, Knockdown, Airborne pressure, and the official-style status-chain example.
The collected developer-combo material uses Castella to create Break and Stun opportunities, then receive the sequence again after Lute and Aria extend it. Community reports also pair Castella with Theresia, Roxy, Kalien, or Astria for different goals.
