Unit:RegisterEvent("Saurfang_Bloodlink", 60000, 10)
Unit:RegisterEvent("Saurfang_Phase1", 5000, 1)
Unit:RegisterEvent("Saurfang_Phase2", 5000, 1)
end

function Saurfang_Phase1(Unit, Event)
if Unit:GetHealthPct() <= 75 then
Unit:SendChatMessage(14, 0, "You are stronger than i thought you are!")
Unit:CastSpell(72173)
Unit:CastSpell(15578)
end
end

function Saurfang_Phase2(Unit, Event)
if Unit:GetHealthPct() <= 33 then
