wiki哪句写不受火伤加成了

总觉得是高级黑。。。

Concentrated Effect increases the Area Damage caused by linked skills, and reduces their Area of Effectradius.
The reduced Area of Effect radius modifier will affect any area of effect produced by the linked skill, even if those AoEs do not deal area damage.
For instance, the Chaos damage from Poison Arrow is not Area Damage, it is damage-over-time which is applied to any enemy within an area of effect. Concentrated Effect therefore will not increase Poison Arrow*s damage, but it will still reduce the radius of its AoE.
这是关于集中的描述，毒云属于持续伤害，伤害不受集中加成，但是会减小范围

关於正火，感觉有很多不解之谜

Concentrated Effect increases the Area Damage caused by linked skills, and reduces their Area of Effect radius.
The reduced Area of Effect radius modifier will affect any area of effect produced by the linked skill, even if those AoEs do not deal area damage. The reduction will therefore apply to curses, auras, Elemental Proliferation, and so forth.
我看到的wiki。。。

说的很明白，fire damage对自身烧伤加乘无效，对怪烧伤有效

这是毒箭的解释，受集中效应加乘

集中效应和你完全说的相反，你在哪个网站找的
