OSRS Nightmare Zone Calculator

How Nightmare Zone points work

Each boss is worth its combat level squared over 1,000, rounded down, and the dream multiplies that by a figure that grows with every boss the dream can spawn. In hard mode the multiplier is 0.05691804 times the bosses' combined combat levels squared over 1,000, plus 41.32125: 230.1753 with all 50 bosses. Normal mode uses each boss's normal combat level and pays far less. Turning bosses off lowers every kill, and Dream Mentor's three bosses without Desert Treasure I's four cut every kill to a sixth, so keep both or neither. Essyllt is worth double. A party splits each kill's points by damage, so your points an hour follow your own damage.

Dreams and what they cost

Pay for dreams from Dominic's coffer before you drink the potion. A death in a dream is safe, except for hardcore group ironmen and, from 4 November 2026, on Hardcore Worlds. Practice is free and gives no points or experience, and one practice dream in 100 brings the lobby cow in place of the boss you picked. Endurance fights every boss you have once, in turn. A rumble spawns your bosses at random, up to four at once when you are alone, until you die or leave; a hard rumble stops paying at 1,048,575 points, and you are logged out after 6 hours. A customisable rumble lets you pick at least 5 bosses. You need 5 of the quests above to play at all.

Bosses with a catch

Slagilith takes about a third of the damage from anything but a pickaxe, but gives experience for the whole hit. Tanglefoot takes damage only from the magic secateurs the arena hands you. The Dagannoth and Gelatinnoth mothers change colour every 18 seconds and each colour takes one kind of damage. Chronozon dies only after all four blast spells hit him, so he needs 59 Magic. Hard mode's Untouchable reflects a fifth of your damage, and hard mode's Everlasting shrugs off much of a ranged or magic hit. Arrg, Dad, the Ice Troll King, Moss Guardian and many others give extra experience a hit, which the table above counts.

Power-ups

In a rumble, one power-up at a time appears and lasts a minute if you leave it. Recurrent damage adds a second hit of three quarters of each hit for 45 seconds; the Zapper hits the bosses near it for about 3% of their health every two ticks for a minute; Power surge refills your special attack by 20% a tick for 45 seconds, so a special attack weapon pays; Ultimate force kills everything in the arena for no points. Damage from the Zapper and Recurrent damage gives no experience, but its kills still pay points.

Absorption, overloads and imbues

Dom Onion sells absorption at 1,000 points a dose, overloads at 1,500, and super ranging and super magic at 250, all usable only in the dream. At 1 Hitpoint every hit on you takes 1 point of absorption, which is why most players use a locator orb or dwarven rock cake after the overload. Each overload lasts 5 minutes, and the potion timer counts it down so you know when to drink the next. Imbuing one of each item, with one mask or helmet and one salve amulet, costs 7,825,000 points, and the Hard Combat Achievements rewards halve every imbue. The Soul Wars calculator prices the same imbues in Zeal Tokens, and the DPS calculator takes your whole loadout against any boss. The melee training calculator sets the dream beside every other melee training spot for your account. Herb boxes cost 9,500 points, 15 a day, and roll the herb table 7 times.
