Revelation Online – Grand Bulwark Expert Mode – Dungeon Guide

The way till First Boss:

1. Kill all the trash Mobs on your way. (Marker 1)
Depending on Grade, Gear and Level, I recommend to lure smaller groups.
Cause these mobs can hurt a lot, especially in 3 Star.
2. Watch out for Barrels on your way, if you get too close, they will trigger and Explode.
The AoE-Damage of the Barrel-Explosion is pretty high and can one shot players.
So be careful! (Marker 2)
As soon as you reach the Ramp, make sure your Team will stay at the Bottom.
Try to aggro a few (not all) of the Mobs on top of the Ramp,
and lure them down to your Teammate.
Kill the Adds, then repeat, if needed.
After clearing the Platform on the Top of the Ramp,
You need to roll on “Rock, Paper, Scissors” with the NPC on the left way.
If you win the roll, you will unlock the Way to the Wolf Rider Boss.
To asure to win, you will have a few people to leave the raid and open GB up again,
and roll on “Rock, Paper, Scissors”, which ever person clears the roll,
you all leave the Dungeon exit party and join on them.

First Boss: Wolf Rider

The mechanics of he first Boss are pretty simple.

Skill/Talent recommendation:



  • Lure the Boss to the Corner
  • Tank the Boss there, till he has 10% HP (Position 1 on the Picture)
  • below 10% he will start his charge without a chance to control it
    just burn it.


– Laser:
Boss will channel a Laser into the direction of a random Person

  • This can be dodged by dashing left or right.

He charges towards Target with highest Aggro (Tank) and push it back.

– 100% Catapults will be spawned at Position 1 and 2
Kill both asap, then move to the Boss
(If they attack, they mark a Spot on the Ground, dodge it!)
– 82% Archers will be spawned at Position A
Kill them asap, use CC´s to disable them
(best will be you split your Teams on certain positions)

Last Boss, Second Form

Qǐsù ba = Just die

Skill/Talent recommendation:

1. BladeMaster: Withering Soul (3Star) (for Burn phase below 10%)
2. Vangaurd: ShieldStorm, Light Shield
3. SpiritShaper: AoE-Heals for aggroing CrossWolves.


  • Start tanking the Boss at Position 1
  • Spiritshaper will be positioning at Position 3
  • Short after start the first Jumping Face (Ground Slam) will start.
    (See Attacks below)
  • Next he will do a Howl, which will spawn CrossWolves at Position W.
    (See Attacks below)
  • if needed: Slow DPS around 75%/ 55% / 35% / 15% and wait for the Jump-Phase
  • After each Jump-Phase, Push the boss to the next Mechanic
    (and save your Combos)
  • At 70% / 50% / 30% / 10%, he will be spawning Spirit Wolves (Pos.1 and Pos.2)
    Kill them before they reach the middle, else the Party will be Wiped.
    In case you get caged in the Middle, shout it out, so your Teammates know.
    Do not stand on the Arrow-Line nor the Circle on the Ground,
    this will grant a Movement-Speed-Buff to the SpiritWolves.
  • He will do this all over again, till he dies. So: Howl, Jump, Spirit Wolves, and repeat.
  • Below 10% you will need to Burn the Boss, so try to not go past, until you cleared the Spirit Wolves.
    else he will Enrage and do the GroundSlam permanently.
    To Burn him you have a short Time-Window of approx. 5 seconds.
    So make sure to save your highest Damage Skills, for that Burn-Phase.
    I recommend the BM Using its 3 Star ability “Withering Pall” for the Burn Phase.


– Ground Slam (Jump-Phase): “Qǐsù ba”
The Boss will lift his Arms, and scream “Qǐsù ba” to initiate the Jump phase.
He will do 5 GroundSlams in a row, that you have to avoid because:
He will get a Heal-Stack for every failed Jump (if someone got hit).
Try to jump properly. At 30+ Stacks you wont be able to out-dps the Heal anymore,
and the Boss will start to reset Phases.
-> This can be dodged by 4 normal Jumps, followed by a double jump.
(When he shouts “Ba” start Jump > Jump > Jump > Jump > Double Jump)
– Howl: (CrossWolves)
The Howl will paralyze everyone in a 10m Radius, for 5 sec.
Everyone outside the Range will get a small amount of Damage.
With the Howl hes calling/spawning CrossWolves at Position W.
Don’t stand in the way of the CrossWolves, if they hit you,
the Boss will get Attack-Buff-Stacks.
Those need to be Aggro’d by AoE-Heals of a SS. Lure them to Position 3 and kill em.
-> can be dodged by simply passing by, or walking away from their direction.
– Charge:
The Boss will be Jumping away from you, then Charge at you with full Power.
-> can be dodged by dashing left or right.
– Tripple Scratch:
The Boss will try to Scratch you several times, which has a Knock Back effect.
He will Scratch you 3 times, the third will hurt a lot, so you want to avoid it!
-> can be dodged by dashing through him (forward)
I recommend using ShieldStorm, Fearless or LightShield during that.

(Percentages might not be a 100% accurate)

100- 90% Jump Phase short after Start
Howl and spawning CrossWolves
Wait for the Jump-Phase , slow at 75% if needed.
70% Spirit Wolves will be Spawned
Howl and spawning CrossWolves
Wait for the Jump-Phase , slow at 55% if needed.
50% Spirit Wolves will be Spawned
Howl and spawning CrossWolves
Wait for the Jump-Phase , slow at 35% if needed.
30% Spirit Wolves will be Spawned
Howl and spawning CrossWolves
Wait for the Jump-Phase , slow at 15% if needed.
10% Spirit Wolves will be Spawned
below 10% Burn the Boss!
If you don’t kill it in Time, he will Enrage and cast the Jump-Phase permenantly
