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 attacking four 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 if the player is standing in melee-range. It is fairly quick, so Protect from Melee is suggested. However, this attack drains prayer relatively quickly, so an altar and/or rejuvenation potions is recommended. The demon will attack with magic if the player is not next to him (cannot be completely blocked with protect from magic). 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.

Strategy
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.

Special attacks
Yk'Lagor has two Special attacks. They can be avoided by running behind a pillar as soon as the text appears above his head or you hear the voice acting.


 * Magical Drag
 * Yk'Lagor will shout the phrase "Come Closer" and try to drag you in. When he succeeds he will heal 15% per player dragged in. He will stun you for a relatively long time, drain your Prayer and disable any protection prayers.


 * Earthquake
 * Yk'Lagor will shout the phrase "This is..." and jump into the air. When he lands he shouts "TRUE POWER" while shattering the ground. He can hit up to 990 LP, thus killing the player in 1 hit. With this special attack you will have a little more time to run behind the pillars.

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


 * Melee
 * As long as everyone is close to him, Yk'Lagor will use his melee attacks. They can be completely blocked by Protect/Deflect Melee. You won't take any damage, but with each attack he will drain a few Prayer Points. This will be a huge Prayer drain if you solo him on a 5:5.


 * Mage
 * As long as 1 persons stands away from him, he will rarely use a Melee attack. He will always use Magic attacks, which hit everyone in the room. The damage can't be blocked with Protect/Deflect Magic and you will get hit if you stand behind the pillar.

Killing Yk'Lagor Without Taking ANY Damage Method
Yk'Lagor the Thunderous can be killed without taking any damage, as first 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, independently 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 Group Gatestone outside boss door.
 * 2) Go inside the Boss room, drop your regular Gatestone at Yk'Lagor's Back side (his Back side is one step closer to the pillars than his front side).
 * 3) Draw the attention of 4 Mages and Yk'Lagor will break free. Run behind the pillars now.
 * 4) DON'T teleport out when Yk'Lagor breaks free, his first attack is ALWAYS Magical Drag. In a 5 man team it's easier if 4 persons stay behind the pillars and 1 persons runs 1 spot north or south, and directly behind the pillars again when Yk'Lagor shouts "Come Closer". If you happen teleport out before he did the Magical Drag attack, it will be the first thing he'll do once you get inside the boss room or Gatestone in, which will be virtually impossible to avoid then.
 * 5) Now the real fight starts. Pot up, set your Quick-Prayers/Curses to Protect from/Deflect Melee, Piety/Turmoil, and if you have the Ancient curses active, Berserker and Leech Defence help, make sure to have a decent amount of Rejuvenation potions and at least 60-70 Prayer points, then activate your Quick-Curses/Prayers (Make sure to have Protect/Deflect Melee activated) and then Gatestone tele inside the boss door.
 * 6) Make sure to make another regular Gatestone and drop it. After dropping the Gatestone, hover your cursor behind the pillar ALL THE TIME while focusing completely on Yk'Lagor. As soon as he shouts any of his Specials you CLICK.
 * 7) From now the fight is pretty easy, he will keep attacking melee and use his special attacks every 5-8 attacks.


 * 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).
 * It is possible and advised in a 5:5 team to teleport next to the boss when you ran behind the pillars, thus not using the group gatestone unless your prayer reaches 0.
 * When your prayer reaches 0 don't run behind a pillar immediatly since Yk'Lagor will switch between all 5 players thus almost taking no damage untill he uses his Special attacks. Once behind the pillar you can gate out to pray.
 * In a 5:5 team with all people attacking it is possible to kill Yk'Lagor with around 70-80 Prayer points using only melee protect/deflect.

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

Trivia

 * 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 log in, although you don't really unlock the soundtrack in your Playlist.Glitch!.png
 * 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.)
 * It may be possible for Yk'Lagor to be the strongest monster in Runescape in a 5:5 dungeon, therefore shattering the Corporeal Beast's long standing record.
 * With the addition of this boss, this is the first time voice acting has appeared in the game aside from the tutorial.
 * Yk'Lagor has the highest maximum hit in the game, being 990, done by his Earthquake special.
 * After freeing of after Yk'Lagor performs his Earthquake special, the camera will automatically move to show him.
 * The Misterious mages are also voiced.
 * Before freein Yk'Lagor, the soundtrack that play is "Yk'Lagor the Thunderous", however this is not the main tack itself as it haves a different tone.
