The KVM weapons we "modified" were not doing what I think you all understood them to be. Part of that was in the way the description was worded to maybe state that 5% defense ignoring per refine. it never did that, the slaughter bonus lvl 1 = 5% per refine. So at +14 it would give (14 - 5) * 5% bonus demi damage..
The effect we updated was to instead of (ref - 4) * (ref - 4)% demi damage increase. So at +14 it would do 10 * 10 for 100% demi damage, but at level 6 it would do 2* 2% demi damage. It is a linear progression now rather than exponential one. That is all the bug fix was and almost all of you will benefit from it.
(The GX issue was fixed a long time ago, explain what "slaughter" does in your mind, because somewhere what you think, and what we think is not synchronized apparently)
Can you fix the "Destruction Bonus" to do the same as the "Slaughter" one??
