At first my dicussion with rsa on github
rsa:"Wrong. many spells require modify this states, see yourself in SpellWork by flags, "state features" work not only in TOC, in Uld/ICC also. This spells - not require currently. if need - add needed mask to spell (absent now 8-)"
me: "How I can seperate current spells with should modify this state AURA_STATE_LIGHT_TARGET and AURA_STATE_DARK_TARGET. SPELL_SCHOOL_MASK_ARCANE | SPELL_SCHOOL_MASK_HOLY or SPELL_SCHOOL_MASK_ARCANE | SPELL_SCHOOL_MASK_SHADOW are wrong, spells with that mask are only in XT-002 encounter, bloodqueen and npc 37126"
rsa: "light/dark aurastate used mostly for NPC targeting, not damage mods. for XT event his used to PowerSpark moving, in Svalna event - to Spear targeting, in Putricide event - to Clowd targeting/damage mods. Most spells, that modify AS absent in DBC (see targeting 70352, 70353 for example). Possible in this case - same (see 3d effect of 66001 for example).
