When am I supposed to face Messmer?

[Sean Maxhell]

I found where this boss is hiding very quickly, went in, saw it, left it alone to explore a bit.
I've practically explored almost the entire map, I'm just missing two areas, defeated a lot of bosses that give me memories.
I miss the mega dragon, something to do with Santa Trina and the green area at the top left.
My Messmer is still there. What's the point of facing it? Does he unlock something? Does it block something?

he gives you an item you need to burn the tree to enter the "late game" stage of tthe dlc

I feel like Scadutree 10ish is where it starts being a normal thing to do. I suspect the right builds on strong players can beat him earlier, but I suspect a lot of people will be coming back to fight him after exploring some more.

You need his flame to burn a tree in the ruins past the Shadowkeep in order to reveal the last zone.

Idk but I'm level 10 and he was pretty easy. I got him down to one hit on the first try. Don't be afraid.

Whenever you like. Though if I had to guess. I think he's meant to be the 2nd to last boss you face after beating all the other optional ones, but I did not do that because I am impatient and stubborn.

Straight up lies. He is a boss that has to be killed but there are several after....

I reached him and left him the hell alone. I'm on NG+4 and he hits like a truck, i'm instead exploring all locations and killing optional bosses, doing NPC quests etc. will come back to him when done.

At +10 to +12 ideally, but if you can get even higher go for it.
