You will need newest Eluna.
Here is an example:
When using .ccs ingame, you cast spell (triggered) entry 11 (frostbolt) on your target (or yourself if no target).
local function OnCommand(event, player, command)
if (command == "ccs") then
player:CastCustomSpell( player:GetSelection() or player, 11, true, 500 )
The spell has spell effect 0 set to &Spell::EffectSchoolDMG, // 2 SPELL_EFFECT_SCHOOL_DAMAGE
I checked this in the DBC files. See http://www.pxr.dk/wowdev/wiki/index....bc#188.8.131.5240
By default this spell will do damage of 1000 and the basepoints0 are 1000 (999 in DBC file)
The function use here will have bp0 set to 500, so the damage output will be 500.
