In Dark Souls 3 you can infuse many different Weapons and Shields with Gems that change the properties, damage type or Scaling. In order to infuse a Weapon or Shield to your chosen type you must:

  1. have found and give the appropriate Coal to Blacksmith Andre,
  2. have a Gem of the chosen type, and
  3. have the required Souls.

The exceptions here are Refined, Raw or Fire which require no Coal to be given. You can use a Shriving Stone if you wish to remove the Infusion from your Weapon or Shield (this must also be done at Blacksmith Andre). Again, not all Weapons and Shields can be Infused so check the Weapons pages to verify which can and can't.

These weapons CANNOT be infused:BowsGreatbowsCrossbowsChimesTalismansStaves, Pyromancy Flames and any weapon that upgrades with Twinkling Titanite or Titanite Scale

      Because it's not listed here, weapons infused with heavy, sharp, refined or raw gems can still be buffed with resins and spells. All other infusions preclude buffing of any kind. Heavy and sharp gems also reduce or outright remove scaling of the inverse of the scaling it increases, i.e. heavy gems reduce dex scaling and sharp gems reduce strength scaling.

        To all the people who don't understand why they didn't get the achievement, make sure you've really done the infusion. I was in the same situation when I suddenly realized the Deep Battle Axe in my inventory was looted from a Mimic, not infused by myself.

            Something i found is that it can't infuse executioners greatsword. It scales with normal titonite. Anyone know why it can't infuse.

              Dev's got LAZY with this aspect of the game. Most infusions hurt my base damage. Unless I'm keeping a D&D monster manual of every enemy and their weakness (this particularly applies to elemental dmg, scaling or no) I'm better off with straight upgrades and MAYBE a heavy/sharp/refined infuse. LAAAAME

                  When I infused my offhand shield with a blessed gem, the HP recovery continued when I two-handed my mainhand weapon. If I were to do the same with a caestus, would I continue to get the bonus, when two-handing my main weapon?

                    scaling confusion12 Jun 2016 16:07  

                    So I was about to infuse my uchigatana with a sharp gem for it ot get better dex scaling but I noticed that the C scaling it has does not go up to a B scaling in dex even if I infuse. The C in dex does become blue indicating it is getting some scaling but does not become a B. So is it even worth it, or is it better to wait and just upgrade the weapon normally until the scaling goes up and then use the gem? Or are there different levels of scaling even within the same letter? Like you have a high C scaling and a low C scaling in dex and I am just making the C scaling better with the sharp gem. Kinda confusing.

                      For the use of Magic Weapon03 May 2016 01:47  

                      Which infusions can I do that still allows me to use spells similar to Magic Weapon? I've noticed that it works on some, but not others.

                        I did all the infusions listed and my achievement didn't pop up, is there another requirement here? I used the shriving stone to see if that would work.

                          probably a dumb question but...21 Apr 2016 13:06  

                          do infusions themselves have levels to them I.E. if I have a fire weapon and want to add another fire gem to it is that a thing? I'm a noob so sorry for the noobish question

                            Where is the Mage's Coal? its needed for crystal, blessed, and deep infusions, and no one, online has found it! There's even an achievement for getting all infusions that needs it! I get the feeling its in NG+ or NG++. T-T

                              Might be worth noting:17 Apr 2016 09:18  

                              You can use pine resins on weapons that only affect your base damage and scaling (sharp, raw, etc).But not on weapons that add aux bonuses or different damage types.
