Constellation Tower

Guide

Constellation Tower is the ruined Endless Tower, now taken over by the constellation Betelguese #20994. Your party climbs up to 75 floors of monster rooms and then chooses how to finish the run: an easy exit through a dimensional gap on floor 25, or the Betelgeuse fight on floor 50 (up to 3 stars) or floor 75 (up to 5 stars). On the Betelgeuse fight you can make the boss stronger at the Altar of Goddess, and the stronger you make him, the more Meteorite materials and treasure boxes you get.

Entering

• Getting there: Captain Janssen at /navi alberta 214/77 sails you to the island (e_tower) for 10,000 Zeny. He only takes characters of Base Level 240 or higher. A Huge Vortex at /navi e_tower 30/30 takes you back to Alberta.
• First visit: walk up to Oscar at /navi e_tower 72/116 and listen in on his talk with Leticia. This starts the Destroyed Tower quest and is needed before he will open the tower.
• Party: you must be in a party. The party leader talks to Oscar and picks Create Constellation Tower, then every member talks to him again and picks Enter.
• Cooldown: entering gives you Aftereffects of Tower Entry/Exit, a daily cooldown that resets at 04:00 server time. Once it has passed, talk to Oscar to clear it and you can enter again.
• Time limit: the instance lasts 1 hour and closes after 5 minutes with nobody inside.
• Late joining: you can't enter once Betelgeuse is defeated.

Climbing the tower

1. The party leader talks to Oscar at the start of the tower (1@ch_t 46/188) to begin the climb. Only party members standing inside the tower at that moment are registered for the run.
2. The tower is a loop of five rooms. Each new floor fills the current room with 30 to 35 monsters, picked at random from the Constellation Tower monster pool, so every run looks different.
3. When every monster on the floor is dead, the party leader clicks the portal at the top of the room. Everyone is moved to the next room and the next floor spawns.
4. Every 5th floor also spawns a random tower MVP in the top-right corner of the fifth room. You do not have to kill it to move on: only the normal monsters count.

Skipping floors

Next to Oscar in the first room is a brazier. The party leader can offer Meteorite Powder #1000372 to it to jump 4 floors ahead and land in the fifth room. The first jump costs 50 dust, and each further jump in the same run costs 25 more (75, 100, ...). You cannot jump past floor 75.

Choosing your ending

The portal behaves differently on three floors. On these floors the leader gets the choice straight away, without clearing the room first.

Floor	Choice	What happens
25	Head into the gap	The run ends with the easy Naght Sieger #20996 fight. You cannot come back to the tower.
50	Challenge Betelgeuse	Betelgeuse fight with abilities from 0 to 3 stars (max 600%).
75	(automatic)	Betelgeuse fight with abilities from 3 to 5 stars (max 1000%).

You can also keep climbing at floors 25 and 50.

Floor 25: Naght Sieger

1. Taking the gap brings you to the Altar of Goddess. Here it only works as a healing fountain. Talk to Oscar and he sends you on to Leticia.
2. The party leader tells Leticia Let's do this! and Naght Sieger #20996 walks in to fight.
3. Once Naght Sieger drops to 90% HP, he summons 4 Entweihen Crothen #20997 around himself. They vanish after 15 seconds and are summoned again for as long as he is alive.
4. After he dies, talk to Leticia. Each player gets 1–2 Meteorite Fragment #1000373 and 1 Naght Sieger Soul #1000396.
5. Talk to her again to leave. Leaving gives 20–40 Instance Points.

Floors 50 and 75: the Altar of Goddess

After the portal you arrive at the Altar of Goddess.

1. The party leader walks up the path to wake the altar, then talks to Oscar twice: once for the story and once to open the way to the top floor.
2. Before going up, the party leader can use the altar to change Betelgeuse's five sealed abilities. Each ability has a star level, and each star adds to the boss's total power %, which decides your rewards:

Ability	What it does	% per star
HP	+300,000,000 max HP per star	15%
ATK	+5,000 min / +7,000 max ATK and +100 STR/INT per star	20%
Recovery	Faster HP regeneration and bigger heals when players die	30%
Resistance	+100 RES and MRES per star	50%
Trap	Which traps appear and how hard they hit	85% (totals: 85 / 170 / 255 / 340 / 425; a 3-star Trap counts as only 235 on floor 75, although the altar shows 255)

The maximum total is 600% on floor 50 (every ability at 3 stars) and 1000% on floor 75 (every ability at 5 stars).

Altar options (paid in Meteorite Powder #1000372, party leader only):

Option	Floor 50 (3-star)	Floor 75 (5-star)
Reroll all abilities	1 dust, each ability becomes 0–3 stars	20 dust, each ability becomes 3–5 stars
Maximize	150 dust, all abilities to 3 stars	150 dust, one chosen ability to 5 stars
Seal one ability	300 dust, the chosen ability goes to 0 stars	300 dust, the chosen ability goes to 0 stars

On floor 50 the boss starts fully sealed (0%). On floor 75 every ability starts at a random 3–5 stars.

Lock in your total before going up

Your rewards use the total that the altar last saved, and the altar only saves it when the party leader opens its menu (choosing Quit is enough). On floor 75 the boss already has 3–5 stars everywhere, but if the leader never opens the altar, the run is counted as 0%. Always open the altar once after your last change. Once the Betelgeuse fight has started, the altar can no longer change the stars.

A sealed ability stays at 0 stars: later rerolls and maximizes leave it alone, and the 5-star maximize can't target it.

Going up. When ready, the party leader steps on the switch at the top of the altar area and the whole party is moved to the top floor. This is the moment your reward bonus is decided. Every player gets the bonus that matches the current total: Bonus 1 at 300% or more, Bonus 2 at 600% or more.

Betelgeuse fight

The party leader talks to Betelgeuse to start. The fight has three phases, and Betelgeuse is summoned again at full HP at the start of each one:

Phase	Ends when	What is new
1	Betelgeuse reaches 90% HP	Meteor Storm on a 3×3 grid of spots around him, roughly every 10 seconds. HP regeneration.
2	Betelgeuse reaches 60% HP	Moving ice traps, Ganbantein on a 5×5 grid around him about every 15 seconds, and 2 Soul of Betelguese #20995 about every 15 seconds.
3	Betelgeuse dies	The traps turn into fire traps that knock you back and can kill you outright. Higher ATK.

Mechanics to know:

• Recovery: Betelgeuse heals 1% + 0.3% per Recovery star of his max HP every 10 seconds. Each time a party member dies he heals five times that amount at once. In practice both only happen in phase 1.
• Souls: each wave of souls gives Betelgeuse +100 RES and MRES. Every soul you kill takes 50 back off. Kill them quickly.
• Traps: with Trap at 0–1 stars, 10 traps sweep up and down the arena; at 2 stars, 16 traps sweep left and right; at 3 or more stars, both sets are active. A trap hit costs a share of your max HP: 10% plus the trap bonus in phase 2, 20% plus the trap bonus in phase 3.
• Phase changes: at each phase change the party is pulled to the centre of the arena while Betelgeuse talks, then he is summoned again.
• Stay in the arena: if Betelgeuse is pulled out of the arena for about 5 seconds, he and the whole party are warped back to the centre, and he casts Hell Judgement and Earthquake with boosted ATK.
• Keep the party together: Betelgeuse is immune to damage while the number of players in the boss area does not match the number who started the climb. A member who leaves or disconnects stops the fight.

Rewards

Personal reward. After Betelgeuse dies, every player talks to the Betelgeuse NPC once and receives:

Item	Base amount (T = total %)
Meteorite Powder #1000372	10 + 0.6 × T
Meteorite Fragment #1000373	5 + T ÷ 4
Beteleuse Soul #1000397	T ÷ 100 (max 10)
Unknown Meteorite Fragment #1001599	Same as Meteorite Fragment #1000373, bonuses included

On top of that:

Bonus	Floor 50	Floor 75
Bonus 1 (300%+)	+10 dust, +5 fragments, +1 soul	+20 dust, +10 fragments, +2 souls
Bonus 2 (600%+), replaces Bonus 1	+20 dust, +10 fragments, +2 souls	+40 dust, +20 fragments, +4 souls
700%+	—	+30 dust, +15 fragments
800%+	—	+40 dust, +20 fragments
900%+	—	+50 dust, +25 fragments, +1 soul
1000%	—	+60 dust, +30 fragments, +2 souls

For example, a full 600% run on floor 50 gives 390 dust, 165 fragments and 8 souls each. A full 1000% run on floor 75 gives 830 dust, 365 fragments and 17 souls each. You also get as many Unknown Meteorite Fragment #1001599 as Meteorite Fragments (165 or 365 in these examples, and always at least 5). They are the Slot 2 material at Azzam the Lucky.

Treasure boxes. Boxes appear in the arena when Betelgeuse dies. Opening a box drops its items on the ground.

• Number of stat boxes: total ÷ 50 on floor 50, or total ÷ 50 + total ÷ 100 on floor 75, up to 10. The first five are picked from the Dust boxes, the next five from the Fragment boxes.

Box	Contents
Dust boxes (5)	5–9 of one of Power Meteorite Powder #1000398, Stamina Meteorite Powder #1000399, Meteorite Powder of Spell #1000402, Agile Meteorite Powder #1000400, Meteorite Powder of Wisdom #1000403
Fragment boxes (5)	2–5 of one of Power Meteorite Fragment #1000442, Stamina Meteorite Fragment #1000443, Meteorite Fragment of Spell #1000446, Agile Meteorite Fragment #1000444, Meteorite Fragment of Wisdom #1000447
Critical box 1 (400%+)	5–9 Lucky Meteorite Powder #1000401
Critical box 2 (600%+ on floor 50, 500%+ on floor 75)	2–5 Lucky Meteorite Fragment #1000445

Each Critical box also rolls for costumes:

Total	Floor 50	Floor 75
300%+	5% Costume Dropping Betelgeuse #400147	10% Costume Dropping Betelgeuse #400147
400%+	5% Costume Black Dragon Wig #400148	15% Costume Black Dragon Wig #400148
600%+	5% Costume Black Thunder #400149	20% Costume Black Thunder #400149
800%+	—	25% one of the three costumes
1000%	—	30% one of the three costumes

Leaving. The exit portal in the arena gives Instance Points equal to half the total % (10 points if the total was 0%), within the server's daily Instance Point limit. Charm Of Brightness #30034 adds 50 points.
