War Machine King - Legend Plus

Dumb question: what does that comment mean "will automatically show that players are participating" ??

TAKEN FROM THE OFFICIAL ANNOUNCEMENT:

——————
Special Mission!

Players who clear Liberty Geist Descended! with no Continues from 9/2 (Fri) - 9/4 (Sun) with a Snow Globe Dragon Rouge in their team will receive a special gift: 3 Lv Max Snow Globe Dragon Rouges. Snow Globe Dragon Rouge will also be updated with increased EXP values! Reward distribution dates will be announced at a later time.
*One Lv. 1 Snow Globe Dragon Rouge will also be distributed to users through in-game mail from 9/2 (Fri), 5:00 AM - 9/4 (Sun), 6:59 PM (PDT).

*Liberty Geist Descended! may be cleared on either Mythical or Legend Plus to clear the mission and receive the special gift.
*The special gift will only be distributed once, even if players clear the mission on both the Mythical and Legend Plus difficulties.
*Clearing the mission conditions will automatically show that players are participating in the event.
*Snow Globe Dragon Rouge must be included in the team as a sub member. If it is used as a Leader or used as a friend’s Leader, players will not be eligible to receive the reward.
*Multiplayer clears are invalid. Players must clear the dungeon by themselves to get the prize.
*The mission can only be cleared once.

TL;DR:
Clear any of the two difficulties (NO STONES, SOLO) with a SNOW GLOBE ROUGE (RED) in your team (SUB, NOT LEADER) within FRIDAY-SUNDAY, and get 3 Snow Globe Rouges as rewards.

Good luck, bros! You can inherit skills into your Snow Globe so they have more purpose in your team!

How do we know that we cleared it and that we will receive the reward ?
I cleared mythical solo with a snow globe but I have no indication or anything that I cleared the campaign

Cao Cao
Scarlet
Scarlet
Scarlet
Snow Globe Rouge (Inherited Awoken Kagutsuchi's skill)

Wasn't too bad, actually! But I cleared it on mythical instead of legend. LEGEND IS DIFFICULT! Guess I better do it in multiplayer lol

Awoken I&I (Pentamaxed)/Nut/A.Orochi/Hatsume/Globey/Ryune (Pentamaxed)

40k HP, Heals like crazy with just three hearts and oh so prongy. The only problem is stalling at the right points but actually seemed quite reliable.

Floor 1: Used Hatsume and a couple of prongs then stalled on green until everyone ready to go.

Floor 2: Nut and Hatsume OHKO.

Floor 3: Ryune OHKO red stalled and whittled on green until everyone ready to go.

Floor 4: I hate this one, burst him down before he gets Bindy using Hatsume/ Nut and combos.

Floor 5: Just messed about really. Kept eliminating all poisons and and healing when he absorbs blue let him do whatever he wanted saved some blue for when resolve wore off and used snow globe to activate leader skill and smashed him.

Floor 6: I tried using Hatsume and Nut and it didn't do the whole job, used Ryune and I&I to finish in time.

Floor 7: Stalled forever waiting for everyone to wake up, when everyone was ready for the party I used Orochi and destroyed at my leisure!

I used ronove as my snow globe leader. I actually did not inherent any skill onto him though, no coins :/

On the floor with the blue resolve dragon, if you hit him to 1% triggering his resolve and their are poison orbs on the board, he will prioritize Auto Freezer (changes poison to water) over the 70k attack + self-heal. I found that out by doing too much damage with Myr and not caring about the 70k, but never got hit by it.

Floor 6: "Hi there. You wouldnt mind me hitting you for over one million damage right? Your Grodin's and Drawn Jokers have nothing on me."

The main question is....do we wait 3 days or 3 weeks for the results

Total insanity like Star Justice.

Mzeus/hathor/raph/apollo/apocalypse
partner hosts and ideally brings a delay, light orb makers, and 7sbs to have raph up on F1
F1: P1 activate gears with AOE. P2 pop raph and heartbreaker to kill.
F2: Raph blocks pre-empt. P1 one-shot
F3: Raph blocks pre-empt. P2 one-shot
F4: P1 one-shot
F5: P2 pop Hathor and disable resolve. Then kill.
F6: Kill within first 3 turn countdown. Just be careful with poison orbs.
F7: Pop delay and make sure we both hit 6 combos.

Done it with Sumire Hypermax L and FL, Ult.Andromeda, A.Orochi, A.Isis and Dragon Rouge in Mythical without problems. Delay in the very last boss just in case you dmg isnt enough.

And Legend-Plus, same team cuz i forgot to change Rouge by my other Ult.Andromeda XD!

Machine killers melted everything: A Horus / Armor Horus / Amon / War Diety Yomi / Jormungandr / Sephiroth.

Solo BMyr does this safely, too. BMyr [Urd] / Sumire / Sumire / Amon [LMeta] / Sharon [Urd] / BMyr [Urd]

Done solo with Myr (not a Snow Globe team).

Leader: Myr, +297, skill max, HP + 2×RCV + 2×SDR latents.
Sub 1: Apocalypse, +297, skill max.
Sub 2: Apocalypse, +139, skill max.
Sub 3: Sun Wukong, +297, skill max.
Sub 4: Rei Sirius, +1, skill max.
Fr. Leader: Myr, +297, skill max, HP + 2×RCV + 2×SDR latents, inherits Saria.
Badge: HP +15%, cost -300.

I failed many many times to make 6 combos on boss, but was still able to tank and/or heal.
Was finally able to land 2 consecutive strikes and killed him.

Why is this 7-month-old campaign message on this page still here? Should it be taken down? It's old.

My farm team for this dungeon-
Aizen leads
Revo hades
Awoken okun
Revo haku
Khepri

Hades active on Alfecca to kick resolve. Be sure to do enough dmg to one shot. If you don't do enough dmg to kill, he'll kill you if his hp is too low.

Awoken okun active on last floor. The delay will give three turns to kill and dmg boost. First turn, I clear the locked fire and wood orbs. Next I use haku and khepri actives. Haku should give decent dark orbs and khepri will help avoid the combo absorb. Two dark crosses will definitely kill. If haku doesn't spawn enough dark orbs, you can use aizen's active afterwards for the last turn. Should do the job.

Feel free to wipe everything else as fast as possible. Alfecca and the last floor are the only worries. Doesn't really have to be this team. Just be sure to have gravity active for alfecca and delay active for the last floor. Combo bonus actives help too, highly advised if running cross leads.

Good luck on invade rates and arm drops. Hope this helps.
