All party members that plan on entering this mission must have this Campaign Op active. It is not possible to enter the BC once the Beastmen have regained control of the Icelands, even if the Campaign Op is active. When clicking on the door to the Throne Room (S), you will get the message: "The door is sealed shut with an evil curse."
There is a 30 minute time limit for the battle.
Buffs including TP do not wear off upon entry.
Holy Water is strongly recommended as the Shadow Lord has a Doom job ability called (Doom Arc). Holy Water macro recommended: /item "Holy water" <me>
Most of the Shadow Lord's weapon skills and job abilities can be absorbed by shadows, therefore Blink tanking his highly recommended.
Uses weapon skills that can hit for 400~1700 damage to a Paladin with no shadows.
Shadow Lord Uses certain abilities/weapon skills based on whether using a single sword or dual wielding.
When Sword Mode changes, hate is reset to 0 on all party members. Suggest that melee watch for this and use a job ability or weaponskill to regain hate.
Note: While switching from 1 sword to 2 and vice versa, he becomes invincible for about 10 seconds.
With 1 sword uses:
possibly a conal AoE.
With 2 swords uses:
Aoe Physical damage, is blocked by 2-3 shadows, causes bind + Amnesia if it connects.
Single target damage, blinked by 2 shadows, causes defense down.
Only used with 2 Swords, deals extreme physical damage.
Absorbed by 4 Shadows.
Ability Soma Wall that absorbs physical damage and restores HP equivalent to the damage taken. This ability lasts 30 ~ 45 seconds and melees should disengage/face away while it is in effect. Duration of the ability can be seen with the orbs in his armor. Normally they are purple but during this ability, they will glow red. Once they return to purple, continue your attack.
The Monk's Formless Strikes merit ability is effective during Soma Wall.
Ability Spell Wall that absorbs magical damage and restores HP equivalent to damage taken. This ability lasts 30 ~ 45 seconds and magical damage should be avoided while in effect. Duration of the ability can be seen with the orbs in his armor. Normally they are purple but during this ability, they will glow blue. Once they return to purple, continue your attack.
"Cross Smash" Cone damage with additional effect "Defense Down".
"Vicious Kick" Single target damage with additional effect "Paralyze".
Spawn Shadow summons 2 clones of the The Shadow Lord; followed by a quick dialogue and an Utsusemi-like animation. Clones have very low HP and defense, but very high attack power.
Appears to only use in 2 sword mode.
Stunnable with Stun, Weaponskills with Stun effect and Bashes.
Clones can be de-spawned by sac method or killed quickly by melee jobs.
Brd sac puller preferred because of hymnus.
/SMN with Fenrir's Lunar Roar, Ramuh's Thunderspark and Leviathan's Slowga work as well.
Use Diaga on SL but make absolutely sure all the clones are up. Otherwise it will only hit SL and recast on diaga may be an issue.
Shadow Lord can do this move back to back and its recommended to have the Rdm cover after a sac pull just in case.
It is recommended no Bard songs are being performing during the Summon Shadow as it may draw hate from person attempting to sacrifice him/herself to get rid of them.
If the clones are alive, during a special ability of the Shadow Lord, they will do the same so it is advised to dispose of them as soon as possible.
Also uses weapon skills that have a Dispel effect.
Seems to rage at 20~25% of hit-points left, using weapon skills and job abilities not used earlier in the fight.
Doom Arc does 300~700 damage with extreme knock-back effect after a short dialogue and inflicts a 10 second Doom.
Implosion inflicts Max HP Down and does 200~500 damage to party members within the area of effect.
Summons clones much more frequently during the last 20% of his HP.
The phrase fiat lux is a reference to Genesis 1:3 ("And God said, Let there be light: and there was light.") In Latin, the full passage is dixitque Deus fiat lux et facta est lux. The phrase fiat lux has become something of a vulgate, understood to translate as "let there be light" (although, "let light be made" would be more accurate). Given the nature of this Campaign Op- that is, overthrowing the Shadow Lord- the vulgate definition (let there be light) makes sense.
