Yk'Lagor the Thunderous

Yk'Lagor the Thunderous is the final Dungeoneering boss monster encountered on the occult floors (36 to 47) of Daemonheim. A Dungeoneering level of 89 is required to fight him. He is a Kal'Gerion demon with a high rank, it is unknown however, if he is one of Kal'ger's generals.

Unlike other bosses who are simply 'there' when the player enters the room, Yk'Lagor must first be freed before he can be fought; upon entrance to the boss room, Yk'Lagor is bound to the ground and surrounded by a barrier that appears to be held by several mysterious mages in the room. After killing a few of the mages, the demon will roar, "My turn!" and break free from the barrier, causing the room to shake and killing the rest of the mages with a single blast of magic.

Yk'Lagor's standard melee attack involves slashing the player with the blades on his arms. It is fairly quick, so Protect from Melee is suggested. The demon will attack with magic if the player is not next to him. Yk'Lagor also has a powerful move where he jumps up and slams into the ground, generating an earthquake. Additionally, he can grab the player with magic and throw him across the room, which stuns the player for a short time (This should be AVOIDED at all cost, otherwise the demon will heal). Both the earthquake attack and the grab attack can be dodged by running behind one of the pillars in the room. Due to the nature of his special attacks, it is recommended to attack him with magic and use a protect from magic prayer.

Yk'Lagor says the following lines, which are all voice acted:


 * RELEASE ME! (when bound)
 * My turn! (when breaking free)
 * You dare steal my power? (when killing the mages)
 * Come closer! (before grabbing the player)
 * This is... TRUE POWER! (when using his earthquake attack)
 * Another kill for the Thunderous! (after killing the player)

Concepts about Fighting Yk'Lagor
Yk'Lagor has two Special attacks:


 * "Come closer": You have little time to run behind the pillar, otherwise Yk'Lagor will heal a large amount of LP (around 1/5, which equals to around ~2k LP on 5:5) while dragging you next to him, dealing a massive instantly Prayer drain, disabling your protection Prayers and stunning you for a relatively long time (all of this at the same instant when you're grabbed in), making you extremely vulnerable to his fast high-hitting Melee attacks. Try avoiding this at all costs, his 2k LP healing effect is what makes him be considered "unbeatable" by first timers. Also, if you happen to be dragged in, don't panic and just GGS tele out. He'll have healed, but you can wait outside the Boss room until the Stun and Prayer disabling effect fade so you can keep fighting it later.


 * "This is... TRUE POWER!": This one seems to have a little more time to run behind the pillar, yet if you fail to do so Yk'Lagor can easily hit up to 990 LP (on 5:5). This special can destroy your XP by the end of the round with Deaths penalty, as it can easily one-hit somebody with 99 Constitution and 99 Defence wearing a full armour set at full LP (this attack hits up to 990 LP on 5:5).

Both of these specials can be avoided by running behind a pillar as soon as the text appears above his head or you hear the voice acting.

Apart from his Special attacks, Yk'Lagor will behave in a pattern depending on how you're fighting him.


 * As long as you're close to him, Yk'Lagor will attack you with Melee. His melee attacks can be completely blocked by Protect/Deflect Melee. Even although taking zero damage, everytime he lands a Melee attack on you while you have Melee Prayer on, Yk'Lagor will a drain a few Prayer points. His fast hitting Melee attacks can add up to a massive Prayer drain in case you're trying to solo him on a 5:5 (still very possible to do so without taking any damage at all, just requires a lot more of Rejuvenation potions -- No Damage method is explained very well in the next section).


 * As long as you stand away from him (out of his Melee attack range), Yk'Lagor will attack you with Magic attacks. You can't pray against his magical attacks, and they hit on the 300-400+ (on 5:5).


 * Once you kill 3 Mages and draw attention from the 4th (or simply attack 4 different Mages), Yk'Lagor will break free and start fighting you. His first attack will always be a "Come closer" special (check the section below for more detailed info on how to kill it), after this Yk'Lagor will use *at least* 5 Melee attacks IN BETWEEN each Special attack (taking in consideration that Yk'Lagor didn't use any Magic attack, and starting to count as soon as he finishes his special), swapping between "Come closer" and "TRUE POWER!" every special. A typical fight would be like: Yk'Lagor breaks free, kill all the remaining mages and his first Attack is a "Come closer" (first attack will always be Come closer"), he does 5 Melee attacks then a "TRUE POWER!" Special, 7 Melee attacks and a "Come Closer", 6 Melee attacks and a "TRUE POWER".. (check the section below on detailed info on how to kill Yk'Lagor).

Yk'Lagor's Boss room has different rules for Teleporting than any other place inside the Dungeoneering skill. You can only use the regular GateStone teleport or the Group GateStone Teleport if you're standing behind one of the pillars, otherwise you'll receive a "You can't teleport here." message.

Killing Yk'Lagor Without Taking ANY Damage Method
Yk'Lagor the Thunderous can be killed without taking any damage, as firstly mentioned by Mod Chris L on 19-Aug-10. This section will explain in detail one of the possible ways to kill Yk'Lagor on Complexity 6 without taking any damage, independendly of how many people the dungeon is designed for (works from solo to 5:5 Yk'Lagor Boss fights). It requires good reflexes, lagless connection and a decent amount of Rejuvenation potions, but it's completely possible.


 * 1) Drop the GGS outside boss door.
 * 2) Go inside the Boss room, drop your regular GS at Yk'Lagor's Back side (his Back side is one step closer to the pillars than his front side).
 * 3) Kill 3 Mages and draw attention (attack) a 4th Mage (have Magic protect/deflect on if you don't want to take damage from level 65's), or just attack 4 different Mages so Yk'Lagor can break free and start the real fight.
 * 4) DON'T tele out when Yk'Lagor breaks free, his first attack will ALWAYS be a "Come closer" special, you don't have to care about having Melee protection prayer on yet as he'll start with a "Come closer" once he's done one-hitting the remaining mages. Just stay ready to run behind the pillar as soon as Yk'Lagor shouts "Come closer" and you'll have successfully avoided his first special. (if you happen to have GGSed out when Yk'Lagor broke free/killed the mages and didn't do the Come close special, it'll be the first thing he'll do once you get inside the boss room or GS in, which will be virtually impossible to avoid then. So don't tele out before avoiding the "Come closer" special, he'll kill the Mages and cast it without any attack in between so just stand inside the Boss room while he kills the mages and run behind the pillar to avoid his first "Come closer" special.)
 * 5) After having successfully avoided his first "Come closer" special and standing behind the pillar (this is a safespot, also), you'll be able to GGS out safely. So do it, and prepare yourself to start the real fight. Pot up, set your Quick-Curses to Deflect Melee, Turmoil, Berserker and Leech Defence (or your Quick-Prayers to Protect Melee and Piety or your highest offensive stat boosting Prayer), set your Auto-Retaliate ON, make sure to have a decent amount of Rejuvenation potions and at least 60-70 Prayer point, then activate your Quick-Curses/Prayers (Make sure to have Protect/Deflect Melee activated) and then GS tele inside the boss door.
 * 6) If you did everything correctly so far, you'll be facing Yk'Lagor's Melee attacks without taking any damage at all. Make sure to make another regular GS and drop it (you'll have 5 Yk'Lagor's Melee Attacks safe time to make and drop the regular GS before he uses another Special attack). After dropping the GS, hover your cursor behind the pillar ALL THE TIME while focusing completely on Yk'Lagor. As soon as he shouts any of his Specials ("Come closer" or "This is... TRUE POWER!") you CLICK. If done correctly, you'll have avoided another of Yk'Lagor's specials and will be at a safespot. GGS out.
 * 7) Both of his specials can be avoided easily by running behind the pillar, so from now the fight is pretty much a repetition of steps 5-6 until Yk'Lagor is killed. You'll take absolutely no damage if using this method, but you'll need Protect/Deflect Melee on all the time and Yk'Lagor will drain Prayer points with each of his Melee attacks, thus you'll probably need some Rejuvenation potions for recharging Prayer points (an altar can be used alternatively for a limited amount of Prayer points).

This strategy works great even when Soloing a 5:5 man Yk'Lagor boss, as shown in this Video Guide.

Trivia

 * With the addition of this boss, this is the first time voice acting has appeared in the game aside from the tutorial.
 * On the day of release, Yk'Lagor the Thunderous' music track's unlock info reads "This track unlocks default info." This is similar to the glitch that occurred to the wilderness volcano's theme, "Eruption".same as the other bosses in in the occult floors.


 * When Yk'Lagor shouts "This is... TRUE POWER!" it could be a reference to the game Soul Calibur 4 as the final boss Algol shouts the same thing when he leaps into the air during one of his attacks.
 * There is a glitch that the sound track of "Yk'Lagor the Thunderous" may be played when you login in, although you don't really unlock the soundtrack in your Playlist.
 * The Mages binding Yk'Lagor The Thunderous are chanting "Heim crabs are awesome." backwards, meaning they are saying "Emosewa era sbarc mieh". (This was confirmed during the Q&A session at Runefest.)
