Just an FYI:
 * Upgrading XSRs and XURs require gems (level 90 is 5050 gems, level 110 is 6050 gems.)
 * if maxing their atk/def, despite their low gem costs, it is advised to add the arcanas while they are still level 1.
 * XLR require same amount as LR/HLR/GLR but instead of just gems, it will also need gold, iron and ether
 * upgrading costs of XLR from level 110 to 130 is fixed at 900k for each resources
