Ok, I have circled the summoning altar with workbenches and started to deforest the place. Seems like the altar now has a base that continues down to the bedrock so no cheesy teleport there but scouted few good locations for them.

Made full stacks of obsidian and needle arrows. More meads are brewing and going to make another bow once I have raided the swamps for materials even if one fully upgraded bow should be enough for couple hundred arrows?
2 stacks of fire arrows as a backup should finish the job and they light her up nicely if the fight goes well into night.

Instead of exclusively using arrows, use the bonemass skill as well. Get on in there and melee their health down. It's much faster.

If you're confident, she is quite killable in melee with using the bow only til she lands.

This sounds like a plan and going to wear full set of wolf armor tho I'm not too confident as remembering her to be one though cookie in melee.

I wonder how a few ballistas would help...

Sadly I don't yet have access to that technology but it would have been interesting to kite Moder and let ballistas shoot her down.

Have a chance to climb to his back. When it happens she only stays on the floor without being able to attack you.

Will try to circle her in melee and try this out even if it would result in a not so great battle experience but a victory is a victory and I'll take it

So much to do, so much to prepare but happily spend this time for not to die miserably
