这玩意有个战记，掌心朝前可以噗一下

以下摘自fextralife送灵火条目：
This pyromancy flame leaves trails of fire during its casting animations, which will damage nearby opponents. This can boost the damage of spells like Black Flame at extremely close ranges, or simply hurt enemies that get too close when you're casting something like Profaned Flame.
The fire trails only appear for offensive spells, not buffs. Floating Chaos also doesn't make fire trails.
简单说就是施放攻击性法术会有溅射伤害，对眼前敌人有效，有了溅射伤害总伤害更高。如果你的核心技能是一些爆破类咒术（引燃烈火、净化火焰、黑焰），可以选择送灵火。
施放浮空混沌不会产生溅射。
Requires more stamina than normal Pyromancy Flame for each cast.
送灵火消耗更多绿条。
Even if you have less than 15 strength, pyromancies casted through the flame will consume the same amount of stamina and will be dealing the same damage.
没加满15力不影响伤害。这条据说是错的。
