Reforge in Nioh is a process by which you can reroll the various attributes of your Weapons and Armor. By selecting a specific attribute that you want to eliminate from the piece of equipment, the reforging process will replace that attribute with another, selected at random, from an available pool of possible attributes. Requires Senji Tome.

Reforging an attribute requires 2 Spirit Iron Chunks, which can be acquired by playing through missions or by disassembling Rare and Exotic weapons. Some attributes cannot be acquired and some attributes cannot be changed. You cannot change attributes that can be transferred through Soul Matching and you cannot change attributes that have the hexagon symbol, like the inherent Damage Reduction or attributes that belong to one specific armor set (like Warrior of The West etc). You cannot acquire attributes that belong to different attribute pools and you can't acquire attributes that belong to specific armor sets. Reforging can change ability lines, but it cannot add more ability lines. Start with rare equipment to have access to more ability lines. After selecting a weapon for Reforging, you may press Triangle to change the Reforging Material from Spirit Iron Chunks to Divine Fragments or Anima Stones. Using Divine Fragments greatly increases your chance of acquiring rare attributes. Besides Divine Fragments and Spirit Iron Chunks, the player may spend Anima Stones and Glory, for a chance at acquiring a multiplayer specific attribute. You may also press Triangle from the Reforging Menu to bring up the Tempering Menu. Tempering uses Umbracite to manually change attributes to other attributes of the same type.

 

Re-Forging Melee Weapons

 

 

Melee Weapons have 8 exclusive pools and 1 non-exclusive pool. The non-exclusive bonuses can appear in any pool, but can be quite uncommon, and all or none can be present at one time. The non-exclusive pool is made up of: Break, Parry, Parry (Critical), Ki Reduction (Critical) and Proficiency Bonus in addition to the 8 exclusive pools which are listed below and only one of each pool can appear on a Weapon. Some Weapons come with fixed/locked bonuses that cannot be rerolled.

These values below are preliminary values, please edit the tables with any new higher values you encounter. White Text representing the max roll at 0 Familiarity, Blue Text Representing the max roll with max Familiarity.

      Damage Pool 2 is completely wrong Low/Mid/High/Quick/Strong Attack Damage all cap at 20.9% with max familarity, not 24.9% like they say, i wish it did. im pretty sure there are even more errors here as well.

        Does anyone know what the maximum Status Ailment Augmentation is on a roll with max Familiarity? I can't find it anywhere on the net

          Blows my mind how empty the wikis are for this game (across all wikis) when every other wiki for every other game I've ever played was infinitely more extensive / detailed / up-to-date, wikis of the Souls games included. This is surprising considering how this game has / had a large playerbase, is old, and is far, far from being garbage.

            melee damage effect (the blue rarity base effect) is missing and conflicts with the damage scaling with stat effects

              Soo I got some boots that have the effect 'Life recovery after you purify' So I get a regen effect when that happens but I don't see it here

                So this is outdated... there was a special effect that I had in which allowed me (I think) to combo against blocking enemies, it was a yellow teir effect.

                  I have a sword with final blow damage, can I also reforge a different trait to have damage from behind to go with it?

                  • Anonymous

                    Where is "Skill Ki Reduction"? Also i happen to have "Change to Attack(spirit)" and "Agility Damage Bonus" on the same weapon

                    • Anonymous

                      For anyone curious I have tested extensively all the bonuses and have concluded that Familiarity Bonus of A+(max familiarity with a weapon) equals 15.5% damage increases, Agility Bonus of A+ with Agility of A equals 15%, Enemies Defeated bonus seemed to cap at 8 or 9%, not sure if it time based but couldn't get it higher after clearing the first area so may be higher if you can manage to kill more in a shorter span of time, I got as far as the hut that holds the key with the first Yokai in the game, finally the change to stat on the Katana, my weapon of choice, benefits the most from change to skill A+. I tried the strength, heart, body, and skill all with no skills unlocked and with the exact same stats. Also the biggest damage boost comes from low, mid, high attack currently at 15.9%. If any found an higher values or different results please post. I'm trying to unlock the best weapon possible. Thanks.

                        Is there any possible way to remove the inheritable special effect from a weapon? I have some really really good weapons stuck with one really bad inheritable special effect.

                          Note that damage thing should be divided in two pools, Change to attack and Agility Bonus for example, can be on same weapon.

                            How about paralysis and poison? which pool do they belong? i think i remember getting paralysis effect on my katana or spear before.

                              It takes luck, gold, and LOADS of spirit iron, but putting Bonus Amrita on all your favorite armors is well worth the multiple rolls of the dice to get it.
