Regex Tester & Validator

This regular expression matches specific combat log lines in Final Fantasy XIV (FFXIV) where either Garuda or Raktapaksa begins casting the "Ferostorm" ability on themselves or each other. It verifies a structured log prefix, the specific ability name, and the "gm" flags. This is typically used in Advanced Combat Tracker (ACT) triggers to alert players of incoming mechanics during a raid encounter.
