Hello!
I have a question regarding the operation of the program in Elementals.java
To add elemental atribute, the code:

{
0, // Level 1
25, // Level 2
75, // Level 3
150, // Level 4
175, // Level 5
225, // Level 6
300, // Level 7
325, // Level 8
375, // Level 9
450, // Level 10
475, // Level 11
525, // Level 12
600, // Level 13
}

and
public static enum ElementalItemType
{
Stone(3), Roughore(3), Crystal(6), Jewel(9), Energy(12);

public int _maxLevel;

private ElementalItemType(int maxLvl)
{
_maxLevel = maxLvl;
}
}


But I have a question:
In the current version is working up to level 7, 9 or 13?

If it is limited, how do I increase the max attribute to level 9?

Try use Jewels to add lvl9

("Elemental Type", "ID of ITEM")
fireJewel(FIRE, 9558),
waterJewel(WATER, 9559),
windJewel(WIND, 9561),
earthJewel(EARTH, 9560),
divineJewel(HOLY, 9563),
darkJewel(DARK, 9562);

For me, work fine.

Level 9 is working fine, from freya
But no lvel 12....
Energy works, but you can´t get more than 450 element.

How to find jewel of elements?
