Help❓ Archpaladin Class Quest

Hi guys Im current doing the proof of valor quest to have a archpaladin class there is a part there where i need to kill the dreadhaven general, but when i go to dreadhaven it redirect me to mountdoomskull, so my question is, Do i need to finish all the 13lords of chaos story to unlock dreadhaven? thank you.

Yes and no.
You can just cell jump and try to instantly hit(attack) a monster to prevent auto-kicks.
