Can't Finish Wynnexcavation Site D

There are 3 final forms of Amadel.. it's confusing.
The first form is a wither. I believe it uses the teleport spell.. or charge.. or multihit. After you kill it, another wither will spawn. It has a different attack pattern, and is really annoying. The last form is a humanoid. Half of Amadel's face is a villager and the other half is that of an enderman. Kill him, and get the pendant (I think it's the magma cream texture).

 

Honestly I was unaware that someone changed that old boss fight. The last time I fought it, there was only one wither and the one humanoid Amadel for the final battle. Just do what the others mentioned above and kill the wither twice, and then kill the humanoid form of Amadel in order to get the pendant.

 

Any time this afternoon works for me.
