monster rarity and skill leveling

I'm curious as to if anyone has tested this question out: does the rarity of the monster with a skill being sacrificed have any correlation with the success rate of leveling the skill


Basically, do rank A/+ monsters offer a better success rate than B/+ monsters?

I've never tested it out before, but I'm inclined to say that it doesn't matter. Any skill ups that I've attempted to use have failed or succeeded equally whether or not they were A or B monsters, but of course I didn't record anything so I might be mistaken.

Well as of right now, if I have an A skill and a B skill, I sacrifice the A to the B just in case I get more of the same A to avoid having to evolve it.

can i piggy back on this topic.

can someone shed light on skill stacking? from lvl 4-10 stacks of 4 work but after lvl 11 does the skill stack have to increase ... to say 6?

i'm at lvl 11 now, sacrificed a 4-stack and nothing ... does it need to be a 6-stack now?

Lastly, does the still stack go up even higher after lvl 15 or so?

@fenix, no, you was just unlucky with that sacrifice. (4) stacks are known to fail about 3 - 4 times between skill 5 and skill 20, so it's not that you NEED a higher skill sacrifice. However, I advise you to switch to (5) stacks from here on, a (5) stack has a chance to fail maybe 1 time from skill 5 to skill 20. It almost NEVER fails. I know it has yet to fail for me, lol.

thanks for the reply armitaage!!
