WeakAura for highlighting important debuffs/incoming casts on raidframes.
Features:
Supports most of Raid Frames using LibGetFrame
Have built-in setup for Castle Nathria
Fully customizable pixelglow per spellID
You can add additional aura IDs in cases of multiple debuffs of the same name (huntsman mark as example)
You can setup different glows for different amount of stacks
Allows you to check caster's target after a delay (some bosses changes their target non-instant or having right player in target for a short amount of time)
Tips:
Use different colors and offsets <0 to avoid collision when u need more than 1 debuff to show at the encounter
