Har'Lakk the Riftsplitter

Har'Lakk is a boss encountered when raiding Daemonheim. 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). The style of the attack is indicated by short lines of speech, When Har'lakk mentions Miasma his special 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. 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. It is recommend to bring runes for the 'cure me' spell, which cures poison.

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 dont quickly move.

Slash attack work pretty well on him. Magic can do significant damage with blast spells. Accurate ranging using a shortbow (or longbow if you are hiding out) and Fractite arrows seems to work. 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 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 'falling rocks' attack which will only drain your prayer slowly, but cause you no harm. This can be used to deal great damage until you have run out of prayer.The demon will still continue to use his special attacks, but you can simply avoid the damage by stepping away from the rain and use the 'cure me' spell, should his miasma attack poison you. Leave a Gatestone outside of the room so you can quickly teleport and escape in case of running out of prayer or food. Pray at an altar to receive your prayer points back. Stabbing it with a melee weapon has been proven to be effective.

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).

All portals have a stack effect, it means that the longer you stay on one, the bigger the damage will be.

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 deal over 900 damage). Strangely, unlike the previous record holder, K'ril Tsutsaroth, Har'Lakk can be poisoned.


 * Har'Lakk is a general of the Kal'Gerion army.


 * It is possible for Har´lakk´s rain attacks to continue falling and kill players after he has died.
