RiftMu Custom Jewels: Volt, Max HP, All Stats and More
Last updated: 20 October 2026
RiftMu's custom jewels sit in item group 19 next to the classic set, and only some of them are in circulation. The Volt Jewel and Volt X Jewel level the Amulet of Volt chain and the top wing lines, and the option jewels - Jewel of Max HP, Jewel of All Stats, Jewel of Skill Power, Jewel of Experience and the X-Shop set - each add one extended option to a weapon, shield or armour piece. Everything on this page was checked against the live server files on 3 October 2026; the Castle Siege Volt Jewel reward was added on 12 October 2026, and on 20 October 2026 all ten main option jewels - Max HP, All Stats, Defense, Max SD, Poison, Elemental Damage, Reflect, Double Damage, Skill Power and Combo Power - started dropping in game from events, bosses and hunting (the update news). The classic jewels - Bless, Soul, Chaos, Life, Creation and Harmony - are still the everyday upgrade layer underneath.

Volt Jewel and Volt X Jewel: the upgrade pair
Both jewels run the same upgrade table, so it does not matter which one you hold. Apply one to a supported item and it gains one level, at 100% success and with no failure penalty. The supported items are:
- Amulet of Volt 1 to 200 - an amulet at +15 rolls over into the next amulet at +0, so the chain is 200 amulets of 16 steps each. Amulet of Volt 1 is sold in the X-Shop.
- Dragon Power 1 to 5 - the same roll-over: Dragon Power 1 at +15 becomes Dragon Power 2, and so on up to Dragon Power 5 at +15.
- Wings of Conqueror, Wings of Angel and Devil and Wings of Power - levelled from +0 to +15.
The Volt Jewel is farm-only. It drops from the three 300-million-HP bosses - Abomination, KingZ Lion and Pharaoh (in Lost Land of Tarkan) - at 10% per kill, and from the Deep Dungeon Gorgon at about 7.5% per kill. On Abomination, KingZ Lion and Pharaoh every party member in range gets their own loot roll. The guild master who wins a Castle Siege also receives 5, to share with the guild. The Volt X Jewel is the shop route: it is on no drop table and sells in the X-Shop for Gold Points, singly or in bundles of 50 and 250.
Option jewels: the ten droppable jewels, Experience and the X-Shop set
The option jewels run on RiftMu's Extended Option System. Each jewel is tied to one option: applying it adds that option to a weapon, shield or armour piece, or raises it one step if the item already has it. Every step is set to 100% success, and the jewel is used up on each application. An item can hold up to 10 extended options. Only weapons, shields and armour can take them - wings, rings, pendants, earrings and pets cannot.
- Ten option jewels drop in game, and their number is their rarity: 1 Max HP, 2 All Stats, 3 Defense, 4 Max SD, 5 Poison, 6 Elemental Damage, 7 Reflect, 8 Double Damage, 9 Skill Power and 10 Combo Power. Every Blood Castle, Devil Square, Chaos Castle, Illusion Temple, Doppelganger and Imperial Fort reward, the guild events, the raid bosses, the world bosses and the Golden Invasion monsters roll a jewel pool, and harder content rolls the richer pools. Every ordinary monster on the 64 hunting maps also drops Max HP, All Stats, Defense and Max SD, up to a daily limit per character. The Speed Realm drops all of them three times as often. The jewel update news has every pool and its odds.
- Jewel of Max HP and Jewel of All Stats are the most common pair. Every clock-spawned custom boss, from Ice Queen up to Abomination, KingZ Lion and Pharaoh, has both in its loot table, and both are world drops from monsters of level 60 and up, more often from higher-level monsters. The Raklion of Oblivion elites carry both too, every hunting map drops up to 20 Jewels of Max HP and 10 Jewels of All Stats per character a day, and level-1,000+ monsters add a further capped daily drop of up to 40 and 8. The Hide & Seek finder also wins a Jewel of Max HP. The MU Pass reward track pays 10 of each per pass on the free track, and more on the Gold and Premium tracks. The Arca Battle trophy mix turns 31 to 40 Trophies of Battle into 5 Jewels of Max HP (5 mixes in 6) or 5 Jewels of All Stats (1 in 6). Both jewels are also sold in the X-Shop. They cannot be traded or sold in a personal store.
- Jewel of Skill Power adds +1% skill damage per jewel, up to +10%. Every Crywolf hero gets one, the mid- and top-level event pools and the strong bosses drop it, and the X-Shop sells it. Jewel of Combo Power (+1% combo damage per jewel, up to +50%) is the rarest jewel of all: it comes from the mid- and top-level event pools, the strong bosses and the X-Shop.
- Jewel of Experience adds +1% EXP per jewel, up to +10%. The Guide Quest pays five, level-1,000+ monsters drop up to 3 per character per day, and the X-Shop sells it. It cannot be traded.
- The X-Shop set - Jewel of Attack Power (+1% attack power per jewel, up to +10%), Damage Reduction, Max AG, Full Recovery, Vengeance, PVE Damage and PVP Damage Absorb - is sold for Gold Points only and has no drop source. Defense, Max SD, Poison, Elemental Damage, Reflect, Double Damage and Combo Power are still sold there too, but they also drop in game now.
The collectible jewels: no source on the live server
Vibrant, Blue, Helix Gold, Supreme, Orange, Emperor, ELITE Wings and VIP Wings Jewel still exist in the item list, but nothing on the live server pays them out - no monster, boss, event, box or shop - and no upgrade or option system uses them. Older guides, including earlier versions of this page, described Kingz, High Kingz, plain Helix and Gold Helix jewels, a Supreme-to-White-Dragon conversion and Emperor Jewel ring upgrades. None of that exists on RiftMu today, so do not trade for these jewels expecting a use. The item list also holds 35 more option jewels - Auto Combo, Freeze, Stun, Invincibility and others - that nothing on the live server pays out.
Classic jewels: still the foundation
None of the above replaces the classic set. Quick reference, one line each [Official mechanics unless noted]:
- Bless - raises an item's level up to +6 with no risk of downgrade.
- Soul - pushes item level beyond +6 with a chance of failure; luck on the item improves the odds.
- Chaos - the fuel for Chaos Machine combinations, from wings to end-game recipes.
- Life - adds to an item's additional (skill/damage) option in +4 steps.
- Creation - used to create fruits that permanently adjust stat points.
- Harmony - adds a harmony option to an item; refined from Gemstones.
- Guardian and Gemstone - Guardian imprints level-380 gear; Gemstone is the raw stone refined into Harmony.
For success rates and safe upgrade order with these, see the item upgrade guide.
Farming priorities
The sources below are for the Permanent Realm - RiftMu's long-term, no-wipe world - so a jewel plan built there keeps its value.
Volt Jewels: be at the clock spawns of Abomination, KingZ Lion and Pharaoh, and kill the Deep Dungeon Gorgon; the only other source is the 5 paid to the Castle Siege winner's guild master. Max HP and All Stats: every custom boss tier pays them, so work your way up the boss ladder, and ordinary grinding on level 60+ monsters adds a steady trickle. The other option jewels: play the events at your level every day - Blood Castle, Devil Square and Chaos Castle top levels roll the richest pools - and hunt anywhere for the daily Defense and Max SD drops. Skill Power: make the Crywolf hero list. Experience: finish the Guide Quest and grind level-1,000+ monsters for the daily drop. Every source with its odds is on the item hunt pages.
(The 2026 Summer Edition has ended; when it closed, up to two characters per account could be exported into the Permanent Realm.)
Common mistakes
- Treating classic jewels as obsolete. The custom jewels add levels and options on top; your gear still needs its Bless, Soul and Life groundwork.
- Hunting Volt Jewels in the wrong place. Only Abomination, KingZ Lion, Pharaoh and the Deep Dungeon Gorgon drop them, plus the 5 paid to the Castle Siege winner's guild master. Map monsters, other events and boxes never do.
- Buying "rare" jewels from other players. Vibrant, Supreme, Emperor and the other collectibles have no use here, and Kingz, High Kingz and plain Helix jewels do not exist at all.
- Importing numbers from other servers. Drop rates and upgrade odds are server-specific; check the item hunt pages for the RiftMu figures.
- Selling Volt Jewels to an NPC. They are the only farmable way to level the Volt chain, and other players will trade for them.
