uh should i max double shot? because i have 7 in mastery and 5 in penetrator and 1 in double shot, so is double shot really that good cause at level 1 it sucks -.- PS. does the amount of monsters it hit increase?

DS is a pk and a training skill, you should max it out but don't forget about the glove mastery.
Just remember to increase it by 5 levels each time so it doesn't consume too much mp for too little damage.

how much MP does it take every 5 levels? and should i master DS or mastery first?

Mastery first imo, again 60 extra damage.....plus at NO MP COST!LOL!Well at level 7 it takes 40 mp soo.......do the math.....

the Ds takes 40 mp at level 7? ew

very eww =_= penetrator use to be like 10 and now its 20+ at lvl 6 and its killing my mana pots hardcore...

how is DS a pk skill anyway i have confirmed that it doesnt hitanother player twice only monster

DS does about 400 each hit so about 800 total on a monster.
My ds is at lvl 10 and it uses like 40 mp.
