The 3rd battle was way more difficult than the 4th one.
For the third battle, shadow loch and gear helped me a lot. Also after trying that battle 5-6 times, I noticed that the 5-6th tenebris clone somehow did not get the first turn/Used sneak attack instead of clone and my gear was there to do the rest.In the end I also saw that the 3rd Nebel dupe also did not get the turn and Oak was there to help me out.
As for the 4th battle, purifying mist along with gear and sleepers was more than enough.

Yeah I saw this too. You can sometimes draw out an attack from Tenebris by leaving a monster on 1HP. I guess because the AI for Tenebris is programmed to kill things so sometimes will choose to attack the easy kill rather than follow its normal move order.

Guys what I applaud about this event is them setting up a unique challenge which is very difficult. I often hear from older players that they find most of PvE very easy. However, I agree that this particular case where we have duplicating roaring entrance monsters is a bit excessive. It’s possible for most strong players with repeated attempts but is not great fun to play. I would much rather that duplicates come in at normal speed or they change the battle condition to “all monsters have 99% speed”.

There’s potential with this event, but we’re not seeing it yet. All poison immune and sleep immune were far better. Still a challenge but an acceptable one.

I used my UC team with emerald Using death mark. Battle 3 took 3 attempts because I kept missing sleep on tenebris. Beat 4 on first go but missed nebel 3 times which made it tougher
