Future perion golem map

So since EMS officially is getting this on wednesday I want to prepare a few things for lvl 200+ grinding.

1. Is there a safe spot for mules? (rope, platform?)
last map top left
2. What level do you need to enter this map?
190
3. On Avg how much dmg would these guys do? (mainly asking because my phantom mule have very low hp)

buffed on my ds(cap weapon def and half magic def) , they do almost 4k damage. they hit hard.
