you're welcome. i've also learnt there are rotating bosses in Moonlight Temple and Tombs from Discord server. Each one of the bosses in Tomb drops a different special crafting item for Helmet of the Ancients.
nice. I have 2 of the pieces but what I'm really rather is a werewolf helmet. I think I may have had it earlier in the game but can't remember for sure.
Werewolf Helmet drops from Feroxa boss in Moonlight Temple, but it spawns only on Fridays. It's too strong tho, take care. It has 150k HP and hitting like a truck. I was getting 2-shots without being able to heal when I was level 200-ish. I am much stronger now, gonna take another try next friday.
