Item Upgrading: +1 to +15, Luck and the Chaos Machine

Last updated: 27 August 2026

On a fresh character, upgrade your main weapon first: push it to +9 with Bless and Soul jewels and leave your armour alone until the weapon is done. Kill speed compounds — a stronger weapon means faster kills, more drops and more jewels, so every later upgrade arrives sooner.

The first decision: what deserves your first jewels

New players usually split jewels evenly across their set. That feels safe and is almost always wrong. Armour keeps you alive, but on a reset server your gear is disposable for the first several resets — you will replace most of it within days. The weapon is the exception, because damage converts directly into farming income.

One RiftMu-specific note. On the Permanent Realm, a couple of Bless in your armour is fine if a specific spot is killing you, but the weapon still comes first. Either way, spend cheap Bless freely and hoard the expensive path — +10 and above — until an item will stay with you for weeks. If resets are new to you, the reset guide explains why early gear is disposable.

Item levels +1 to +15: what actually changes

[Official basics] Every item level adds damage on weapons or defence on armour, and higher item levels also raise the stat requirements to equip the piece. The ladder has visual milestones — items begin to glow around +7 and the effect intensifies at the top levels — which is why a +13 weapon is as much a status symbol as a stat stick. Levels +1 through +9 are done with single jewels in your inventory; +10 through +15 can only be done through the Chaos Machine. Season 21 keeps this classic ladder underneath its newer systems, so everything here still applies on RiftMu.

The jewel ladder

Luck deserves its own sentence: it is an item property, not a jewel, and it both improves upgrade odds and adds critical damage chance in combat [Official]. If you can choose between a plain and a Luck version of the piece you plan to push, take the Luck version every time — over a full +9-to-+15 campaign it saves real jewels.

Chaos Machine: what moves the needle

The Chaos Machine lives with the Chaos Goblin in Noria [Official]. Before you press combine, the window shows a success rate — read it, because it is the only honest number in the room. Qualitatively, three things move it:

• The target level. Each step from +10 to +15 shows a lower rate than the last [Official].
• Luck on the item. A Luck item combines at better odds than a plain one [Official].
• Mix value. Adding extra jewels or valuable items to the combination raises the displayed rate up to a cap [Common on private servers].

On RiftMu the Chaos Machine runs boosted success rates compared with official-style settings, so the climb to +15 is far less punishing — but boosted is not guaranteed, and combinations still fail. What happens on failure (a downgrade versus outright destruction) varies by server and by level range, so make your first high-level attempt with an item you can afford to lose, never your only copy.

Upgrade order: weapon, wings, then the set

After the weapon hits +9, wings are the next priority: they add damage and damage absorption at once, which no single set piece matches. Then bring your set pieces up evenly — a set at a modest, uniform level protects better than one +13 helm on an otherwise bare character. Save the +13 to +15 pushes for gear you will still be wearing after your next several resets.

Know where the classic ladder ends, too. On RiftMu, +15 is the floor of the endgame, not the ceiling: the custom jewels — the Volt Jewel and Volt X Jewel for the Amulet of Volt chain and the top wings, and option jewels such as Max HP, All Stats and Skill Power for weapons and armour — drive the progression above it. Both systems apply at 100% success, and the custom jewels guide covers what each jewel does and where it drops before you spend any of them.

Zen and jewel budgeting

The Chaos Machine charges Zen per attempt [Official], and Zen is also your reset fund — on RiftMu a Grand Reset alone costs 50,000,000 Zen, so a reckless +15 campaign can push that milestone back a week. Decide your Zen floor before you start combining and stop when you reach it.

For jewel income, events beat open farming for most players: Blood Castle, Devil Square and Chaos Castle run all day and their live times are on the events page. The Permanent Realm has medium jewel drop rates, with the custom jewels coming mainly from bosses: Volt Jewels only from Abomination, KingZ Lion, Pharaoh and the Deep Dungeon Gorgon, and Jewels of Max HP and All Stats from every custom boss plus a world drop from monsters of level 60 and up. Keep a working float of Bless and Soul in your vault rather than spending every jewel the day it drops — the ladder always finds a use for them.

Common mistakes

• Burning jewels on low-tier gear before you have resets. That +9 short sword will be vendor food in three days; the jewels would not have been.
• Pushing +7 to +9 on a plain item when a Luck version is obtainable. You are volunteering for worse odds on every Soul and every Chaos Machine attempt afterwards.
• Gambling your only copy at +13 to +15. Failure handling varies by server; assume the worst until you have tested it with a spare.
• Ignoring the displayed Chaos Machine rate. If the number looks bad, add mix value or walk away — hoping is not a strategy.
• Levelling the whole set evenly from day one. Front-load the weapon; a fast-killing character out-earns a tanky one at this stage.
• Draining your Zen below the Grand Reset fee. On RiftMu that is 50,000,000 Zen you must hand over eventually — treat it as untouchable.
