Lord of Changes-Greater Daemon of Tzeentch
His magical powers are so great that he is second after Tzeenth himself. His powers are focused on confunding enemies plans and seek chaos in mind. His eyer shine with ruinous light of the very depths of the Warp.
Immortal gaze of Lord of Change can focus any mind - countless mass of champions make pakt with this Greater Daemon and end as a Chaos Spawn. Lord of Change is made from pure magic energy, that why his power is beyond magic powers of any mortal.
This powerfull spellcaster and not- so - weak - fighter can be used in your army as great force. He is 4th level spellcaster and in battle point he is more valuable then Bloodthirster.
His wound 6 and attack 5 make him more powerful wizard then warrior but his 6 strength and 6 toughness and 10 initiative make him - on battlefield- enough dangerous to kill anyone he wants. If you are using him carefully he can be more valuable on battlefield then any other Greater Daemon.
