Smuggler's Notes:	Har'Lakk the Riftsplitter is a mighty demon. He uses massive magical energy to summon hazardous portals which you would do well to avoid. Magic is his strength as well as his weakness.
Drops:	Weapon: Primal rapier, [Rapier (tier 1-10)], [Rapier (tier 1-5)] Misc: Kal'gerion notes (part 2) Free to play drops are shown in white, members-only drops in this colour, and unconfirmed drops in italic. Item groups are shown like [this].
Notes:	This boss attacks with melee and magic attacks. If you pray against magic, you will lose prayer points when you block damage from the magic attack. Har'Lakk also uses special "portal" attacks, which can be avoided by simply running out of them. The portal attacks either straight up damage you, drain your stats or poison you. The longer you stand under the poisonous portal, the stronger the poison becomes. Har'Lakk has low defence against magic. Stab and ranged attacks also work reasonably well. A cure potion should last long enough to make you immune against its poisonous portal attack for the duration of the fight. If you are using magic to fight Har'Lakk, get out of the stat-draining portal attacks as soon as possible. If your magic level gets drained too much, you might end up being unable to cast your spell of choice.
