Loren Deep

Loren Deep — MU Online Event Guide

Loren Deep is the nightly assault on the Valley of Loren. At 20:00 the valley fills with waves pulled from across the whole game — everything from Poison Shadows to Erohim — and the server picks one of two assault patterns at random.

Each pattern spawns three groups in sequence, so the difficulty climbs while the event runs rather than all at once.

Notes

Erohim is in the pool

Level 128 with 3 000 000 health and 1 500–2 000 damage, one copy. He is the single hardest thing the assault can put in front of you and the reason people set an alarm for 20:00.

Two patterns, fifty-fifty

Type 1 and Type 2 both sit at 50% appearance. You cannot tell which you are getting until the first group lands.

It builds over twenty minutes

Group 1 spawns immediately, group 2 at 10 minutes and group 3 at 20. Turning up late means walking into the hard half with no warm-up.

One run a night

Loren Deep fires once, at 20:00. Unlike the hourly invasions there is no second chance.
