You will have to make him stand still by making a tiny Lua script to do so.

Here's a Lua script to do it. (Delete the ai_agent)

local NPCID = 50 -- the id of the npc you want to cast the spell
local FrostBolt = 42842 -- the id of the spell 'frostbolt'
local Timer = 3000 -- The time between each cast (3000 = 3 seconds)

function trash_Combat(pUnit, Event)
    pUnit:Root()
    pUnit:FullCastSpellOnTarget(FrostBolt, pUnit:GetClosestPlayer())
    pUnit:RegisterEvent("Wrath_Spam_Ftw", Timer, 0)
end

function Wrath_Spam_Ftw(pUnit, Event)
    pUnit:FullCastSpellOnTarget(FrostBolt, pUnit:GetClosestPlayer())
end

function trash_LeaveCombat(pUnit, Event)
    pUnit:RemoveEvents()
end

function trash_Died(pUnit, Event)
    pUnit:RemoveEvents()
end

RegisterUnitEvent(NPCID, 1, "trash_Combat")
RegisterUnitEvent(NPCID, 2, "trash_LeaveCombat")
RegisterUnitEvent(NPCID, 4, "trash_Died")

Well this is very complicated ... I just added a new root aura to the NPC via quice , here it is :

42716 0

set his walk and run speed to zero in the db.

[stoneharry]

Use pUnit:Root() in the script rather than a aura that roots. Setting walk speed to 0 will actually make him very fast, not slower.
