Skill leveling

Hey
What do you think is better?  
Use for example 5 Skillbooks from Robin together or each individually?
And are there any percent informations?

normaly I always tried to use 5 together, but I'm not sure about it, so I just want to ask what you are thinking about that

5 in a row. That has the same chances, but you spend less money. Simple as that. 

Greets, hope I could help

5 has better chance to get a skill up. Could also get multiple skill ups, so no loss in doing 5

I does always 5 Skillbooks in a row and i see the benefits all the times.

5 together or 5 one by one have the same chances, Light! But it costs more to fuse them one by one

I know: http://www.optreasurecruise.com/guides/skill-manuals-books/
But in my opinion are better 5 Skillbooks at once.

LOL

finished coby today! Had some luck sunday when I did 5 sb's and it went up twice. Need robin 2 more skill ups

??? How much gems did you used Light?? I found only 16 robin SBs in 8 days!! And which level did you do??

A lot. I told myself to farm 2 x 5 coby sb a day and try. Luckily coby sb are easier to drop then robin. Also my 100th day login bonus streak came along +10 gems! So i dumped it all in farming sb. Now not gemming anymore since robin are harder to get and its just a waste of gems to farm 1 char sb's. Ill see how far I can get without gemming. Hopefully I can get 1 more skill up for robin making her 1 to max.
I think i put in like 25-30 gems total a wild guess

nice job, I'm jealous ahah! I'm going to use all SBs during next x2 Special event, but the game doesn't allow me to store more than 25 SBs for character. I'm very unlucky in training specials :'( do you usually use 5 SBs at the same time?

Yeah, five at one time is the best for lvling up.
