Hello
I recently came upon Lord of chaos
https://www.games-workshop.com/en-GB/Chaos-Lord
And looking at his warscroll, I am not sure if he gets to attack with both glave and sword at once? the glave seems big like two handed, but wording implies use of both... but that would make him even greater beatstick!
Also, Lord of chaos transforms into chaos spawn when killed, or into daemon prince if he himself kills a hero.
Do you need to have points put aside for those models to materialize, like for summoning?
