The Frugal Ruthless Guide to the Recombinator
The Recombinator is a terrifying destruction machine where your dreams go to die. You have two items with good mods, you think, why don't I just smash them together and see what happens? And what happens is they turn into a red powder and then you vow never to use the recombinator ever again.
But this is Ruthless, where we enjoy pain and stretch every mechanic to the breaking point.
##TLDR?
- the recombinator only works one way in Ruthless. The worse way.
- the chance of getting a good outcome isn't that bad for lower level items, lower level mods and being conservative.
- it works best if you're building up a backlog of exalts.
- you can blend mods across items in ways that might surprise you.
- you can craft insanely good gear if you're disciplined and willing to wait for the odds to end up in your favour.
- the gear you make is clean, only the mods you want, no junk. So lots of room to exalt slam.
- you'll burn transmutes, augments, and chance orbs like crazy. If you can't help picking them up, might as well put them to use.
##Who this Guide IS for
You need two affixes to be on the same piece of gear. You're patient, willing to set up a careful loot filter and can handle delayed gratification. You've also got a flow of exalts to take your good items and then make them great.
You have more time than currency, and it makes you sad to end the league with 3,000 transmutes in your stash, but you just couldn't help picking them up.
The recombinator is best for SSF, where you can't just trade currency for gear.
##Who this Guide ISN'T for
You've got two items, they have amazing affixes and you just wish you could bring them together into a single piece of uber-gear. You can't, it won't. The math does not favour you.
You're in a trade league. You farm maps, make currency, buy stuff from other players. That's more efficient, do that.
##The Ruthless Recombinator
In bench league, the Recombinator has two modes. Unpredictable Recombination and Predictable Recombination.
Unpredictable Recombination is amazing, and fun, with a higher likelihood of positive results. You'll see racers making insanely good gear using the recombinator. We don't get to use that mode, because this is Ruthless. We chose this life.
Predictable Recombination is worse. It gives you a tiny chance for donor affixes from two items to be forged into a single item with all the mods you choose. You can pick the mods you want, and see the outcome in advance, which will always be statistically insignificant if you go for your dream 6xT1 piece of supergear.
To recombinate, the items must be the same item class. 1H Axe, bow, helmet, etc. A staff and a warstaff won't merge. Armour's a little strange, some pieces will go together, others won't. Pure ES body won't merge with an Armour body, but an Armour body will merge with an Armour/Evasion hybrid. All rings can merge, so can belts and amulets. You'll figure it out.
Blue or yellow items can yield their mods. The result will be yellow.
Every recombination attempt takes 3-9,000 gold (rising with item level), and then 10,000+ dust. So, you'll need a regular supply of dust, but not a lot, because you won't be pulling the lever very often.
##Pushing the Odds in your Favour You've probably put an object in, looked at the 0.67% chance of success and said, "nope." And walked away. That was the right move. Two T1 mods from one item and two T1 mods from another item will give you a sub 1% chance of success (even sub 0.1%). Since you don't have a lot of them kicking around, the odds won't be in your favour.
But you can push things in your favour if you're willing to compromise.
the item level. Your best possible affixes depend on your gear's item level. You need ilevel 86 for T1 Spell Suppression (20-22%) on Body Armour. But T2 Spell Suppression (17-19%) unlocks at ilevel 77. T1 Life (130-144 Life) unlocks at ilevel 64 for helmets, boots and gloves. If your gear doesn't NEED to be a higher level, target farm a lower tier location. T1 maps start at level 68, so... back to the campaign, and say hi to Kitava when you kill him over and over again.
the mod tier. We want the best of the best. But do you NEED it? T1 Cold Resist (46-48%) unlocks at ilevel 84. T2 Cold Resist (42-45%) is pretty close and ilevel 72. T3 Cold Resist (36-41%) is still pretty great. Wouldn't you rather have a T1 Life and T3 Cold Resist/Fire Resist and then other stats compared to the random garbage you're wearing right now? Just don't tell anyone you're wearing level 66 armour to hide your shame.
the number of mods you're trying to merge. One mod from one item and one mod from another item gives a surprisingly high chance of an outcome. Even the fanciest ilevel 84 T1 merger is in the 20%+, but an ilevel 66 with T2 mods can be 50/50 or even higher.
use sacrificial mods to move a perfect mod to a perfect base. Let's say you've got T1 Spell Suppression on a crappy body piece and you want to move it to an ilevel 86 top piece of gear to craft further. You can use the worst mod on the good base with the perfect mod on the bad base and the resulting outcome will be randomly chosen, including perfect mod, perfect base.
##The Stats
I'm going to give you a couple of examples, but just experiment a bit. The results will fall into: "almost guaranteed", "50/50", an "acceptably low chance" and "absolutely not, are you crazy?"
Let's start with a piece of level 66 gear, what you'd get from Ravaged Square in Act 10.
The odds. Mod count is everything:
| Mods you demand | Measured odds |
|---|---|
| 2 | 32–85% |
| 3 | 7–36% |
| 4 | 2.45% |
Each extra demanded mod multiplies your odds by roughly ×0.3.
- Rarer mods give worse rates (check Craft of Exile for mod rarities).
- Gold is flat per attempt for a given class and item level (~3,000 at i66).
- valuable mods cost more dust. My i66 attempts predicted to cost 3,000–21,000 dust.
Now, let's move to endgame stuff, level 80+.
Here's the same ask — one mod from each parent — as the parents get fatter and the mods get rarer:
| Parents | The ask | Odds | Cost per attempt |
|---|---|---|---|
| i83 rares, 4–5 mods each | 2 T1 mods | 5.63% | 8,632 gold, 43K dust |
| i83 rares, 4–5 mods each | 4 top mods (the dream) | 0.07% | 8,632 gold, 67K dust |
Let's put it together with this handy, highly accurate guide:
😌 almost guaranteed (75%+) · 🪙 50/50 (40–65%) · 🎲 acceptably low (15–35%) · 💀 are you crazy? (<6%)
| Mods you demand | i66 | i66 rare mod | i70 | i70 rare mod | i80+ |
|---|---|---|---|---|---|
| 2 | 😌 | 🪙 | 🎲 | 🎲 | 💀 |
| 3 | 🎲 | 💀 | 💀 | 💀 | 💀 |
| 4 | 💀 | 💀 | 💀 | 💀 | 💀 |
Now that you understand how the odds are stacked against you, here's what you can do.
##Strategy 1 - Be Realistic, Target High Success Combinations
You can get 2 really good mods on a lower level base with a perfectly reasonable chance of success. For example, grab a level 66 body with T1 life and another with T3 fire res and you're looking at 75% success. Or even T1 mods, no problem, your odds are totally fine.
It's like a really well-rolled blue item for some gold and dust.
Then add a third mod with T3 cold res and you're down into the 33% range. So, you'd need to mash a handful together to get the one you want, but if you set your loot filter and keep an eye out for bases to transmute, the parts keep flowing in on their own.
Now it's like a really well-rolled regaled item for some gold and dust (and your time). Replace it when you need, but it could serve you better than a piece with only one good mod and a bunch of junk.
And importantly, it has only the mods you want and no junk, so plenty of room to exalt it up to be even better.
##Strategy 2 - Be Strategic, Target Two Dream Mods and Room to Grow
Getting your hands on a high physical DPS weapon is insanely rare and difficult in Ruthless SSF. Even a T3 %Phys (135-154%) has a 0.201% chance of dropping as a mod. T1 Adds (34-47) to (72-84) Physical Damage is 0.403%. And to get both requires multiplying those odds together. It isn't going to happen often.
But if you set your filter wide to pick up every white, blue and yellow 1H axe, for example, you'll be filling up a quad tab with them. Transmute all the whites, augment all the 1-mod blues, and judge the yellows. If any give you mods you want, set them aside. Over time, you'll get all the mods you want, even super rare ones, like T1 chaos res, T1 spell suppression, and T2 flat phys (come on, has anyone ever seen T1 flat phys?).
Crappy bases with perfect mods need an extra step to launder them into better bases. This step is pretty safe, and you'll merely lose about 50% of your gear. You'll regret every swing with a Tyrannical %phys on a Woodsplitter, get that mod onto a Vaal Axe first.
But don't obsess about it, the high end weapons are surprisingly similar in DPS and you'd be glad to use any of them.
As soon as you get two pieces that go together, put them in the recombinator. Depending on the rarity, you'll eventually get a piece of gear with two perfect mods that you want. If it's 33%, then you just have to mash 3, but even 15% only means 6-7 tries. You'll get that faster than a 6-link.
Then exalt to put on the other 4 mods (Allflame lets you choose the best out of 4 each time, which is insanely good).
##Strategy 3 - Be Patient, Better and Better Gear Accrues Over Time
You've mastered the low-level combos and the perfect 2-mod item. Now put it together and try to make a 3-mod item that's high level and "pretty great." Steer clear of the extremely rare mods that will tear your chances down. Settle for T2 life or T2 resist instead of trying to get the T1s.
Gather your parts as you're mapping and whenever you have two pieces of the puzzle. Usually you'll destroy them, but occasionally (5-10% of the time) you'll get a recombination to stick and you're set for that slot, pretty much through end-game once you see how the further exalts land.
I measure the number of projects I should be working on by the number of Orbs of Transmutation in my stash. If they're building up, I need to be rolling on more bases.
After a while, you're getting more and more pulls at the lever, and your gear slots will fill up with perfection one by one.
Once you've got 3, don't get greedy and try to get 4. Did you see where I mentioned 0.07%?
Good luck!
