if you ask me, it would be easier to just make the value of Jewels the same as the value in your own country
1 jewel is 1$ or 1Euro and so on

though countries like Japan would be a different matter as they use the same value setting as in Fairytail (well not the same but similar as they dont use any low numbers, having to use 100 yen for a can of soda (meaning 100yen would also be 1$/euro)

saves me from calculating, but I am open for everyones thought on this
I did change it for now into the fairytail value, added the $ value behind it as well as that was my own target value/ pay for the job

also added CHizuzu's limit on copying dragon slayer magic, basically its split, she cannot get access to dragon force or secret arts by just adding a normal dragon slayer mage mode to her body
but for the same matter she can only add dragon force slayer mode from dragon slayers who are in dragon force mode, so she will get the secrets arts and dragon force only without access to the normal spell list
to get full access she needs to take in both sets though that also has the problem of having to force the dragon immunity off, temporally shutting down that elements slayer type for a day and taking double damage from that element.

this is because she wont become a real dragon slayer so she cant get dragon force by just taking in dragon slayer magic, and vise versa, just taking in dragon force wont make her a full class slayer
so she needs both sides.
