cap on violet gems?

hey well heres the thing.
ive tried lvlin weapon prof for blades on my old tro got it to lvl 18. at lvl 18 with 8k attk, 250pct violets + nd i got about 3pct in 8hrs. now ive just made my new wat-war-tro and i need to get his blade prof up to standard. so heres the question, is there a cap on violet gems? cuz if i put 10 svgs that wud be abt 3 times faster then before which means ii would be getting about 25pct in a day at lvl 18. which basically seems unrealistic =/. also is it better to one hit the stakes with draggys or put violets to increase the weapon exp.
thnks for the help in advance xD

Voilet gems are calulated like this

exp X : 100 = Y

Y * pct voilet gems = Z

exp X + Z = Ur final exp

So with 300 pct voilet gems you get 3 times as fast.

With 10 SVGs(100 pct), it wude go 10 times faster than normal.

someone was talking about something similiar in my server except with moon gems..
cant exactly remember but there are exact % youve to reach for it to give that exact ammount ...something like having 175 percent wont give lets say the extra 75% or maybe 25% honestly cant remember what it was .. but his the top player in server n has basically leveled everything to fix , he fixed nix in 4-5 days got max prof n so forth so i dunno why he'd lie about it .. wish i coulda helped more , guess next time i should pay more attention to what he was sayng xD
