Mercenary option help

I have a question for attacking power mercenary I am lvl 107 my main sword is Indigo 116+E (80%) stats are atk+3% critical damage+3 str +3% critical rate+3 second sword is dark general's sword atk 135(80%) attack power is 1814 when I switch the swords around my attack power drops any help as to why?

 

Its because one is +E refine and the highest attack is at +0

 

Dark Element atk +4% Vit+3 aggro+20% guard Rate+6% magic barrier+1000

 

Then that should me the higher sword would give more power because 116+E is 116+10 means a total of 126 atk

 

Haha sorry bud thats not how refine works

 

Wow then it's worthless to have a sword with atk power of 135 if it is weaker then my sword with atk of 116+E

 

Refine +E DOUBLES your total weapon atk according to its formula so the +E refined would have 232 atk not 126.
Obviously 232 > 135 but thats true for the 135 one as well 135+E > 116+E

I think I explained this already was it you or someone else? If it was you I guess I should have explained it in a simpler way.

 

Some one said that the letters ment E=10
D=11
C=12
B=13
A=14
S=15

 

Yeah but like I said even if E = 10 doesnt mean it will only add 10 atk
Refine for weapon is weapon attack + (refine number)^2
Square of +E is (10)^2 which is equal to 100
Means +E will give weapon atk +100% ^^
+100% of 116 (2x of 116) gives 232

 

so iff refine c my atk weapon will add x300%???

 

+C is weapon atk+144% not x300% or whatever you are thinking.
so technically multiplies your weapon atk by 2.44

 

i dont understand. but iff so,just up to E can be powerfull. thats why i look many coment hard to refine E. mybe?

 

and last where best farm refining material should i go????

 

for the primary refine materials:
Damascus ore-helps refine from 0-8 sometimes 9 is either Lutaros cavern those soldiers (stone soldiers or something)
Even rockasaur from Darkanon plain

For next one i.e mithril ore
Spring of rebirth A1 the big soldiers (sorry forgot exact names xD)

For the last material i.e Orichalum
You've got to feed your spinas to Mr.Sololo

Here's a guide of refinement I had in my bookmarks; it tells about the maths working behind it
