八真魔就是16点真伤，与其他属性无关

8（魔杖）+8（火刀） 楼上说的没错

火刀不是吃0.5嘛？？ 不是按4真来算？？

按我的理解，8魔真无火精通打0减益的时候，就是8（魔杖）+4（火刀）+4（点燃），打有减益加成的时候，就是8（魔杖）+4（火刀）

8真魔有火精通打0减益的时候是8（魔杖）+4（火刀）+4（点燃）+2（火精加的点燃伤害）打有减益加成的时候（33%以下），就是8（魔杖）+4（火刀）+【4（点燃）】*2/3+2（火精加的点燃伤害）。如有不对请指正。

还是说8真魔有火精通打0减益是8（魔杖）+4（火刀）+12（点燃）+2（火精加的点燃伤害）？

减益增益应该不会影响火刀的伤害，火刀是先决定总伤害，后决定持续时间的。我记得很久以前好像确实有个bug是对手的减益持续时间太短会导致烧伤debuff在打出伤害前就消失，现在不知道还有没有。减益加成这个词条影响的是你自己的减益持续时间，不是施加给别人的。如果不考虑持续时间不足一秒打不出伤害的情况，只有牺牲这类先决定持续时间的伤害会受到减益持续时间的影响

火精通应该是加2总伤害，每跳伤害应该比不带火精通的低。上述结论纯属我脑子里两年前读wiki的记忆，不保证正确

又看了一遍wiki，痛苦诅咒，盗贼割裂，包括火刀，它们的总伤害确实是会收到减益持续时间的影响的。火刀基础持续时间是一秒基础伤害一点，火焰精通的额外持续时间会把它增加到三秒，基础伤害3点，从而完全避免了持续时间被减到低于一秒导致的伤害丢失问题，非常有价值，但缺点是近战连续多次击中时可能会导致打伤害更慢一点，但影响不大

Since nearly all Damage/Healing over times have an Interval length of 1 second, these can be simplified to:
Total Duration = Base Duration * (1 + Debuff Duration)
Total Value = Base Value / Base Duration * floor(Total Duration)
Value per second = Total Value / Base Duration
ExamplesExample 1: Rogue's Rupture
Rogue's Rupture which normally does 20 damage, with -17% Physical Power Bonus% and +10 additional physical damage will instead deal 23.3 damage due to having a 50% Attribute Bonus Ratio.
Total damage (before debuff duration) = 20 * (1-.17 * .5)+10 * .5 = 23.3
Rupture lasts 5s and deals damage in 1s intervals, so against a Bard with 25% longer Debuff duration, it will instead deal 27.96 damage
Base ticks = 5/1 = 5 ticks
Total duration = 5 * (1 + .25) = 6.25s
Total Damage = 23.3/5 * floor(6.25) = 27.96 damage
Damage per second = 27.96/5 = 5.592 damage per second
Example 2: Wizard's Zap's Burn
Zap's Burn deals damage with a 1s interval and lasts only 1s total, meaning any negative debuff duration, even -1% (in theory), will make it have 0 ticks and deal 0 damage due to rounding.
On the contrary, it would require at least 100% debuff duration% on the target to get an extra tick from Zap.
NOTE: In reality, if the unrounded # of ticks is very close to a whole number, its susceptible to client-server ticks per second (TPS) variation and can therefore have varying results.
With the Zap example, if the unrounded # of ticks is ~.97 - 1, the zap burn will likely still be applied due to game tick delay.
If the # of ticks is ~.96, the zap burn may happen sometimes, and not happen other times.
If the # of ticks is ~.95 or lower, then you can nearly guarantee that the burn will never properly tick.
以上是wiki的原文，可以看到有5%的减益免疫就能让不带火精的法师少掉点燃的伤害了（该死的网络波动，本来1%就够了）

其实我个人是无脑火精通，3排牧师太强了，没有火精通遇见牧师很难打。而且火伤加5%也能给火球和火刀吃，火刀假设60%魔强，法杖8魔法伤害，那就是（5+4）*1.3=11.7*1.05=12.28。火刀点燃（1+4+2）*1.3=9.1*1.05=9.55
总共加起来还能多一点伤害。

拐精通，拐，火刀，火刀dot，这4个伤害有哪几个吃真哪几个吃加成有没有懂得说一下，上面公式看不懂。。。

这种帖子要顶一下的，另外看到有评论说法师被动火焰精通的，2000+老法师说一下：三排必带火精通（暴力近战拐法可不带，意思就是堆移速伤害纯敲人的），单排双排的话拐法不带（传统法的话，我个人不带，因为其他技能综合来看更好些）
