Acquired From



  • Adds (Spell Buff * 0.9) fire damage to the weapon.
    • Damage is applied each time the enemy is hit with the weapon, regardless of the damage of the attack performed.
  • Damage is increased by the Fire Clutch Ring.
  • Good choice for melee characters looking for bonus damage with minimal stats.
  • Scales well for dedicated pyromancers.
  • Adds roughly 188 fire damage with 40 INT/FTH with a +10 Pyromancy Flame.
  • A few weapons and weapon arts have hidden multipliers that slightly lower the buff's damage per hit.
    Namely, Daggers and Twinblades display this adjustment.
    Regardless, the buffs always remain efficient.

      with 10 int/faith and +0 (110 spellbuff) it adds 89 fire damage which is better than charcoal pine resine, this is very useful when using a melee weapon that doesnt rely on weapon art (since your fp stat is then useless). also it lasts longer than resin. only downside is the use of stamina, but you're not gonna buff your weapon during a fight anyway

        Why is the damage calculation displayed as "Adds 81 * (Spell Buff/100)" instead of the way it is done on magic buffs? "Spell Buff x 0.81" looks simpler and is easier to calculate (it's the same calculation in case if it's hard to figure).
        Also I use this pyromancy on knights as well, especially considering pyromancy flame is essentially weightless and I like to play under 30%. WIth minimum stats and unupgraded fire hand buff is less than charcoal pine resin - but it's "free" ;)

          This pyromancy is pretty good for the Knight class, only needing to invest 1 point into faith, and 1 point into intelligence.

            What are the best weapons to use with this pyromancy? Im thinking the Falchion, good choice?
            I have the bare minimum to cast it, i really just want the cool flame look with the added bonus dmg (not a hardcore player)

              I was testing this spell out.
              For those who are curious about the lenght of the spell effect. It lasts roughtly 90 seconds and can be extended with the ring, Lingering Dragoncrest Ring+0, to ~120 seconds.
              That being said I haven't had occasion to test the lenght of the spell in co-op or invasions, so don't be salty, if it doesn't last as stated above in pvp/coop.

                I have a question. I am using a build with 40 Str, 40 Faith and 40 Int. My weapon is the millwood battle axe. Should I keep using this spell with a Heavy infusion, or should I go for dark/chaos infuse and pick another spell?
                I don't have the coal for dark/chaos infuse yet so I can't do test at the moment. Thanks in advance for your answers :)

                    Equation states 82% efficiency, though underneath it states 188 fire damage (189 for me personally) on 40 int and 40 faith.

                    Testing the Regular flame, and the Parting flame, which have 207 and 194 spell buff respectively. The regular flame added 189 damage, and the parting flame 173.
                    This makes it more like 90 * (Spell Buff/100). It's give or take 1-2 points, between the flames, but interesting to know this buff is much more potent than the listed amount

                      Anyone know how much damage this adds at 10/10 with a +10 flame? I'm wondering if I should run this or just use pine resins. Most people also have poor dark defense so a dark damage resin should be better if the damage is equal.

                        I have a level 270 character with 40 dex, 30 int, 52 str and 50 fth and it actually adds more damage than the Moonlight Blade and Lightning Blade
