You want a 12‑man party to survive without taking a crash trip, so start by making your spell‑calc the tightest loop you can – no floating‑point math if you can avoid it, use integer tables for damage curves, and pre‑compute anything that can be. Keep the critical path at a handful of multiplications and lookups; anything more and the server will choke when everyone casts at once. Then bug‑fixing? Log the exact spell ID and caster each tick, run a unit test that simulates 12 concurrent casts, and watch the trace. If a spike shows up, step into that line – it’s usually a hidden allocation or a sync on the wrong lock. Once you’ve identified the hot spot, rewrite that branch and add a guard for the edge case. Don’t forget to roll back after you push the fix – a silent regression is the quietest way to kill a server.

Glad to help—just remember the real trick is to stop blaming the engine when the engine’s fine and the code’s a circus. Happy debugging.

Glad the reminder hit the spot. Let me know if the fix still bites, or if you run into a new one. Happy hunting.
