War of Genesis: Idle Loot Synthesis and Dismantle Explained

The combine rule is stated inside the game itself: combine items of the same grade to obtain an item of the next grade. It sits next to Dismantle in the Equipment Forge, with an Auto Register button beside them, and the achievements show grades can be pushed all the way to Tier 6.

The game shows you the success rate for the attempt. The 17 September update announcement carries this fix: Fixed an issue where combine success rates for Lv. 5 equipment were not displayed during equipment combining. If the Lv. 5 display was the bug, the combine screen was already surfacing a rate. So ignore fixed percentages from third-party guides and read the number in your own combine window. What the developer has not published is the full rate table, the number of items required and any pity rule.

What is actually in the Equipment Forge panel

The official store screenshot shows a panel with only three interactive elements, which makes it easy to describe precisely:

Element	What it does	Official backing
Combine tab	Turns same-grade items into the next grade	The in-game tooltip text
Dismantle tab	Recycles gear you do not need	The tab label itself
Auto Register button	Fills in materials automatically	The button in the screenshot

The explanatory line in the interface is the hardest evidence on this page. In full: “Combine items of the same grade to obtain an item of the next grade.” That sentence is both the rule and the basis for everything below.

How high grades can go

The achievement list backs this line, so it can be quoted safely:

• Not Bad for a Fusion: craft at least one Tier 4 item through synthesis;
• A Masterpiece from Synthesis: at least one Tier 5;
• Not Synthesis—A Miracle: at least one Tier 6.

The volume achievements also show the loop is meant to run for a long time: Combine First, Think Later (10 times), Synthesis Feels So Good (1,000) and A Synthesis Master Never Stops (5,000).

One distinction matters: Tier 6 appears only in the achievements. In the Steam Community Market sample taken on 2026-09-11 the grades actually seen were Tier 3 to Tier 5, with no Tier 6 listings. So “synthesis can reach Tier 6” is achievement evidence, while “Tier 5 is common on the market” is market observation. Do not blend the two.

Auto-combine now covers jewels too

In the last build, auto-combine handled only equipment and accessories, so jewels piled up and only manual work cleared them. The 11 September roadmap promised a fix, and the September 17 update shipped it.

Per the 14 September FAQ and the September 17 announcement, the rules now are:

• Unlocks at user level 17, opened from the icon at the bottom of the inventory;
• settings let you configure by tier, level, or identical levels, covering equipment and accessories;
• jewels can auto-combine too: set the target jewel tier at the bottom of the existing auto-combine settings window;
• since 17 September, right-clicking a jewel opens the socketing window directly.

The practical upshot: the “jewels I can never clear” problem now has an official answer. But note that auto-combine is not a guarantee of an upgrade. The success rate is right there in the combine window, so read it. What the developer has not said is whether a failed attempt eats extra materials, or whether a pity rule exists.

Where dismantling fits

Dismantling is an official system with its own volume achievements: Useless? Dismantle It! (10 times), Breaking Things Is a Skill Too (1,000) and Completely Dismantled (5,000).

What dismantling returns is not published. What can be confirmed is its position: it sits in the same panel as combining, so it is the other half of gear recycling. In practice its job is to clear space and push unusable gear back into the loop.

The loop you can actually run: farm, sort, combine, dismantle

The sequence below is a recommended route assembled from the interface and the confirmed rules. It is not an official tutorial.

1. Farm. Let stages run; gear keeps dropping. The store copy says it plainly: “As you run stages, gear pours in.”
2. Sort. Open the bag and character panel and group items that share a grade and slot.
3. Combine. Send a group to Combine, aiming for a grade above what you are wearing.
4. Dismantle. Anything that cannot be grouped, or that sits below your current grade, goes to Dismantle.
5. Repeat. The achievement ceiling is 5,000 combines, which tells you the loop is the game.

Choosing between combining and dismantling

If you do not want to deliberate each time, use this rule:

• Can be grouped, and the result would outrank what you wear → combine. It is the only route that raises a grade.
• Cannot be grouped, or the result would not outrank what you wear → dismantle. Holding it only takes space.
• An empty slot is still unfilled → fill the slot first. An empty slot returns nothing.

The full slot and grade structure is in weapons and gear, and judging a single item is covered in best gear and stat priority.

What the developer has not published

This section matters, because it is what separates this page from guides that only look more detailed:

• Success rate: the combine window shows the rate for the attempt, so trust the number on screen. The developer has not published a separate full rate table, so a fixed figure like “30% from Tier 4 to Tier 5” is still not reliable.
• Whether drop and combine rates were quietly changed: a large number of players reported exactly that after 18 September, and the developer has not published a single rate-change announcement. See the drop rate and combine rate dispute after 18 September.
• Number of items required: not published. A pre-launch creator video mentions a “nine into one” figure, but that was describing a different game as a comparison and does not apply here.
• Pity system: not published.
• Dismantle output: not published.
• Exact behaviour of Auto Register: only that the button exists.

The developer says changes are communicated through Steam announcements, so these gaps may close later. This page draws on the Steam official store screenshots and achievements page, plus the 14 September FAQ and the 17 September update announcement.
