[VER 0.6.3]-Enhancing is now added. Type .enhance / .enh <#Inventory ID of card you want to enhance here> <cards you want to sacrifice here>
e.g.
.enh 3 5,10,15 [enhances card 3 by sacrificing cards 5,10,15]
For now, bot will not let you use SR+ to enhance cards because most of the time it's a mistake; in the future there will be a check to confirm if you want to.
Enhancing will give you more exp if you are using the same card to enhance (by 4x).
