Plays a sound and shows an icon when you begin casting Polymorph on a dotted target. Also works for focus and arenaX casting. Will not trigger if the duration of the dot is <1s.
This WeakAura requires macros to know who you're casting on. Macro examples:
/cast Polymorph
/run WeakAuras.ScanEvents("POLY_DOT", "target")
/cast [@focus] Polymorph
/run WeakAuras.ScanEvents("POLY_DOT", "focus")
/cast [@arena1] Polymorph
/run WeakAuras.ScanEvents("POLY_DOT", "arena1")
