By default, this solution cast a lethal and a non-lethal poison, depending of the knowledge and the priority-list (idPoisons[1]=lethal, [2]=non-lethal).  If there is already a poison, and the run time of the poison will be less then 13  min, it will be renewed, if we are 

• not in combat. (We need it before)
• not AFK (who want casting while afk ?!?)
• not Falling, Flying or Riding (mounted) (flying + casting = falling)
• not casting

Why 13 Minutes ? Because of the duration time of a fight with a raid boss. You want more or less ? Change  the 13 in  local timeLeftToCastAgain = 13*60 to another value.

based on WoW 5.4.2.

 

I have learned that casting is not equal casting. There are channeling spells (spells that works the whole time while channeling i.e heal) and spells that works after a channeling time (i.e. poisons)

 

Because of this I changed the code above from

if not (UnitCastingInfo("player"))...

to

if (GetUnitSpeed("player") == 0) and not (UnitCastingInfo("player")) and not (UnitChannelInfo("player"))...

I have add movedetection ( GetUnitSpeed("player") ) also.

can you edit and repost to the original post... Plus Im looking for a LUA Script that would detect a GCD and us a move to Break the GCD. Best example is Empower Rune Weapon for a Death Knight.

Sorry, i cant. I only post the (imho) best solution. If you want to get the old solution change only

 

 

if (GetUnitSpeed("player") == 0) and not (UnitCastingInfo("player")) and not (UnitChannelInfo("player"))

 

with

 

if not (UnitCastingInfo("player"))

 

 

GCD is simple to detect. Use Parameter "Is Spell usable" in the fight class editor.

 

in lua try something like this

local spellid=123456  --[[change to the ID-nr of the spell)]]
local spellname=GetSpellInfo(spellid)
                if (IsUsableSpell(spellname)) then
                    local start, duration, enable = GetSpellCooldown(spellname)
                    if (duration==0) then
                        CastSpellByName(spellname);
                        spell=spellname;
                        break;
                    end
                end

ok I got another one for ya. What would the code Look like if this was for a shaman? You know managing the shaman weapon enchants? I have been trying to figure it out but I have failed a lot.
