For the Invention perk, see Lucky.

Luck is a mechanic that determines the chance for receiving certain rare or special drops and rewards from various sources. Luck was significantly reworked on 27 March 2017 in an update to categorise affected drops and rewards into 4 tiers of luck, each corresponding to one or more luck enhancing items.

Luck enhancers

The following items and relic powers can increase the player's luck tier. Using additional luck enhancers of equal or lower tier grants no additional benefits to luck and all luck tiers inherit the effects of lower tiers. Potions only grant their effect once drunk and last for one hour. Equipment must be worn to grant their effect.

Tier	Equipment	Relic powers	Potions
1	Ring of Luck Pontifex observation ring Strung rabbit foot	Ring of Luck	N/A
2	Ring of Wealth Pontifex shadow ring Collector's insignia (uncharged) Leprechaun hat	Ring of Wealth	Luck potion
3	Ring of Fortune Enriched pontifex shadow ring Collector's insignia (charged)	Ring of Fortune	Enhanced luck potion
4	Luck of the Dwarves Hazelmere's signet ring	Luck of the Dwarves	N/A

Drops and rewards affected by luck

The luck mechanic affects various rewards, including drops from slayer monsters and bosses, rewards from certain skilling activities, and clue scroll rewards. Using luck enhancers increases the chance to receive these rewards, as outlined below. All tiers of luck inherit the benefits of the tiers below it.

Slayer monsters

Increased chance of unique drops such as dark bows and abyssal whips, as well as parts of the crystal key and crystal triskelion key. However pets, starved ancient effigies, sirenic scales, Ascension keystones and signets, and Champion's scrolls are not affected by luck. The monsters affected by the ring's tier will have an increased chance to spawn the elite variant where applicable.

Tier	Monsters
1	Level 1–50 Slayer monsters: Crawling hand, Banshee, Rock slug, Cockatrice, Basilisk, Infernal mage, Desert lizard
2	The above plus level 51–80 Slayer monsters: Turoth, Aberrant spectre, Dust devil, Kurask, Gargoyle, Nechryael, Cave horror, Muspah, Nihil, Aquanite, Jungle strykewyrm, Desert strykewyrm, Skeletal wyvern
3	The above plus level 81–120 Slayer monsters: Abyssal demon, Mutated jadinko, Ascension creature, Ganodermic beast, Spiritual mage, Airut, Lava strykewyrm, Camel warrior, Mammoths, Ripper demon, Living wyvern, Edimmu, Dark beast, Ice strykewyrm, Chaos giant, Tormented demon, Glacor, Nightmare creature, dinosaurs, vile blooms, corrupted creatures, soul devourers, soulgazers
4	All of the above

Bosses

Increased chance to receive a unique drop, such as an Armadyl chestplate or clingy mole, by increasing the chance to hit a boss's unique loot table. The chances to receive boss pets are not affected by luck.

Tier	Bosses
1	Giant Mole and King Black Dragon
2	The above plus Barrows, Chaos Elemental, Commander Zilyana, Dagannoth Kings, exiled Kalphite Queen, General Graardor, K'ril Tsutsaroth, Kalphite Queen, and Kree'arra
3	The above plus Abomination, Corporeal Beast, Gregorovic, Helwyr, Kalphite King, Nex, Queen Black Dragon, Twin Furies, Vindicta, and WildyWyrm
4	All of the above plus Araxxi, Arch-Glacor, Barrows: Rise of the Six, Beastmaster Durzag, Croesus, Kerapac, the bound, Nex: Angel of Death, Solak, The Magister, Telos, the Warden, Raksha, Rex Matriarchs, TzKal-Zuk, Vorago, Yakamaru, and Zamorak, Lord of Chaos.

Luck rings have no effect on boss loot from Temple of Aminishi, Dragonkin Laboratory, and Shadow Reef, since those bosses always roll on their unique loot tables. While luck rings do work on Zamorak, Lord of Chaos, the luck ring needs to be equipped before Zamorak's death as that is when loot is rolled, not when opening the loot chest. Having the luck ring equipped prior to using a chaos die reroll token will also increase the chance of receiving a rare drop when rerolling loot.

Luck has another effect on loot from the Arch-Glacor's hard mode: namely, a chance at an increased number of Dark Nilas dropped when the player receives a Dark Nilas roll based on the tier of luck used.

Rerolling Liberation of Mazcab boss loot with a luck ring equipped will increase chances of receiving rare drops.

4	The above plus: The chance of receiving a Metamorphic geode is increased by 2% total

Clue scrolls

Luck enhancers provide a +1% chance for rarer clue-specific loot, such as god pages and third-age armour, on the corresponding tier of clue scroll. Each tier of luck gives a 1% increased drop bonus for their respective clue types from monsters and skilling.

Tier	Clue scroll levels
1	Easy clue scrolls
2	The above plus Medium clue scrolls
3	The above plus Hard clue scrolls
4	The above plus Elite and Master

Historical luck mechanics

Prior to the luck rework of 27 March 2017, luck was only improved by the ring of Wealth, Collector's insignia, leprechaun hat, and luck potion, all of which:

• Slightly improved the chance to receive unique drops from monsters (but only some bosses)
• Improved the rare drop table access chance and clue scroll drop chance
• Increased the chance of finding gems while mining

All of these items’ effects were identical (charging the insignia doubled its effect) and did not stack.

  • The luck mechanic is reworked, including the introduction of luck tiers and new luck items.

• patch 6 March 2017 (Update):
  • We have added bad luck mitigation to some lore drops so that cumulative monster kills shift the drop rate towards 100% once a certain threshold has been reached. This affects drops which have a drop rate of 1/100 (or worse). For the Last Riders book from the KBD, this does not affect group kills. Players can still gain the kill count in a group fight, but the 100% drop will only occur in a fight on your own, if the threshold has been met. The full list of affected drops are:
    • Adamant dragons (Dragonkin journals, not Forcae's journal)
    • King Black Dragon (Last Riders book)
    • Ripper demons (Miner's journals and the Diary of Jebediah Omnis)
    • Court summons (only if obtaining via monster kills)

Trivia

• Despite working non-stop when worn, luck messages may not appear at some content even if the appropriate item is worn. Whether this is intentional or not is unknown. Examples include:
  • Telos' drops
  • Liberation of Mazcab unique drops
  • The Magister
  • Gregorovic, Helwyr, Vindicta and Twin Furies rare drop table roll
