How To Light Up A Room With Spells?

ClassicSpellActivations is an addon that lights up spell activation overlay for reactive abilities like Overpower in classic World of Warcraft. It supports various action bars and works with default, dominos, elvui, bartender, warrior, paladin, rogue, hunter, warlock, and curse. SpellActivationOverlay uses the retail version of spell proc overlays and spell highlighting when an ability procs or becomes available due to a passive.

Death Knight: Killing Machine, Rime, and Rune Strike (glowing button only) has a default highlight on certain spells when you get procs and such. There is no addon that allows you to pick a spell and highlight it under certain conditions.

ElvUI, a full user interface replacement for World of Warcraft, can be downloaded, installed, and customized using profiles, themes, layouts, and community plugins. SpellFlash is an addon that flashes on top of spell buttons to suggest what spell to cast next. It works with other addons such as Ovale and supports translations and donations.

To fix the issue of the glow disappearing after activating a spell or mounting it on a mount, activate that spell once or mount it on that mount. The addon also makes relevant buttons glow, such as a Fire mage triggering Hot Streak with a glowing Pyroblast button.

Some action buttons associated with spells light up with a glowing gold border, which goes away if clicked or eventually with time. This addon also makes relevant buttons glow, such as a Fire mage triggering Hot Streak with a glowing Pyroblast button.
