Har'Lakk the Riftsplitter

Har'Lakk is a boss encountered in Daemonheim, requiring 35 Dungeoneering. He looks like a purple K'ril Tsutsaroth.

Fighting the Riftsplitter
His main attack is targeted at one person and drains prayer rapidly, but his special attack has three different types (Poison, Damage over Time, Stats Drain). Note that he also has an attack that disables any active prayers (i.e. "you have been injured and cannot use protection prayers!"). This can be very annoying and quite dangerous. In free play the special attacks are changed to two Damage-over-time and one Stat Drain.

The style of the attack is indicated by short lines of speech. When Har'lakk mentions Miasma, a purple rain will poison you, this poison stacks and the damage limit is unknown, being at least over 200LP per hit making him the most poisonous monster in Runescape (see portal section below). If he mentions 'Miasma' on F2P, then it will deal damage over time, identical to the flame portal attack (see below). A cry of 'This will cut you down to size!' will continuously drain all of your stats until they reach 1. Should Har'lakk mention fire in his shout then he summons a fire portal which does continuous, and increasing, damage over time. No matter which way it is a good idea to move. The Poison special attack appears to be the most common and is very hard to dodge without getting poisoned.

"Warning:" If a player runs away from flame rain and reenters, the damage compounds according to the actual time, not time of damage to player. A player running away from rain but accidentally reentering at the end of rain can be dealt over 300 damage!

It is highly recommended to bring Antipoison potions, Cure potions or runes for Cure Me (members only, requiring 71 Magic and completion of Lunar Diplomacy) against the poison and some Stat restore potions against the stat drain. Be aware that while casting Cure Me, you will be immobilised briefly as the spell takes effect, and you will take damage from any portals cast on you during this time. Also, make sure to bring enough food.

Free players are recommended to bring large supply of food for all players, and have good magic defense for ranging or magic, or full armour with stab weapon for tanker. Please notice the boss uses magic attack very often and soloers can have prayer drained rapidly. Similar to members, running across the boss can give time healing the players. Props can be used to reduce portal attack area. Protect from magic will have shorter effect for players but is useful. Team players should not stay too close to each other, and should run across Har'Lakk as it targets the player, time will be given for other players to sneak up on it. In all cases the miasma portal is very dangerous, unless the magic level is considerably high, using magic will risk in drained stat and disabling high-class spell. Rapid restore is recommended for maging, and at least 4 prayer points are recommended in the case.

It is important to note that when he summons a portal, the negative effect of the portal will increase quickly if you do not escape quickly. The fire portal will increase its direct damage over time, the miasmic one will poison you more severely and the stat drain one will drain your stats more rapidly if you don't quickly move.

Stab attacks work pretty well on him. Magic can do significant damage with blast spells. Ranging using the best longbow you can wield and the best arrows you can get work well. Be sure to bring lots of food and try not to stay in one place for an extended period of time. When the boss attacks you, try to run through him so he cannot attack you. Repeat this until he switches targets, but be careful not to run into any of the coloured rains.

One way that seems to drop the number of "rain" casts on you is ranging the demon between the stacks of props, which means that you should stand between the corners, against the wall.

Note that he will only drain prayer if you use Protection Prayers (or Deflect Curses) against him. Using piety or any other boost prayers will not result in prayer drain.

The best way to defeat it is by activating the Protection Prayer against Magic. The demon will use its 'grey sludge' attack which will only drain your prayer slowly, but cause you no harm (as it is a Magical attack). This can be used to deal great damage until you have run out of prayer. He will use no other attacks until your prayer points are on zero, thus making it possible for a player with a very high prayer level, perhaps some means of prayer restoration, and a good stab weapon, such as a spear, to kill Har'lakk before he even started to normally attack the player. Be aware, however, as he might use a portal between the 'sludges', that can deal great damage if you're not paying attention. It's handy to have a familiar out, it cannot be harmed by the portal (nor can Har'Lakk, by the way). The demon will still continue to use his special attacks, but you can simply avoid the damage by stepping away from the rain and cure yourself if you are poisoned, for example. Stabbing it with a melee weapon has been proven to be effective, crush is semi-efficient. Using Ranged or Magic from a distance is a dangerous tactic, as the demon will only use its special attacks which deals very high damage to the player(s), even though Fire spells are very effective to be used against him.

Portals


All portals have a stack effect, it means that the longer you stay on one, the damage will be doubled about every second or so, making the portals EXTREMELY DANGEROUS. So as soon as Har'Lakk shouts one of the lines below, run away. It's possible that he summons another portal immediately after the first one.


 * Red Portal - Flame - Deals direct damage.


 * Purple Portal - Miasma - Poisons. (On F2P worlds, miasma deals direct damage like a flame portal)


 * Black Portal - Shadow - Lowers all stats.

Quotes

 * "A flame portal will flush you out!" (Summons a flame portal)
 * "Taste miasma!" (Summons a miasma portal)
 * "This will cut you down to size!" (Summons a shadow portal)

Trivia

 * Much like the rest of the demons in Daemonheim, Har'lakk appears to resemble K'ril Tsutsaroth, the boss in the Zamorak God Wars Dungeon.


 * His first name sounds similar to Harrallak, the owner of the Warrior's Guild. This is further supported by the fact that Har'Lakk drops rapiers, Harrallak's weapon of choice.


 * Har'Lakk is potentially the most poisonous creature on RuneScape, as his poison stacks (his poison can potentially deal over 900 damage if you are not paying attention). Unlike the previous record holder, K'ril Tsutsaroth, Har'Lakk can be poisoned, because of the fact that the poison he uses is from another realm.


 * Har'Lakk is a general of the Kal'Gerion army, summoned to Gielinor by the Mahjarrat Bilrach.


 * It is possible for Har´lakk´s rain attacks to continue falling and kill players after he has died.
 * Running out of the flame portal attack and back into it will NOT reset the damage done by the portal. The damage starts counting when the first damage is dealt but does not reset until the rain ends, moreover the potential damage increases even if player is away from rain. A player running away from starting rain would be dealt 30, 60, but he will be dealt 120 if he returns just after or 240 if even more time has elapsed.
 * After the Occult floors update, his icon tabs was updated to a newer image, indicating that the Kal'Gerion demons may receive a graphics update to resemble the current model of Yk'Lagor the Thunderous. Their current model may be a placeholder resembling K'ril Tsutsaroth in the meantime.
 * Hal'Lakk is the only known Kal'Gerion demon not to be the final boss of a floor environment.
