I had this idea of a new feature for spell descriptions. Spell cards now update their Damage/Accuracy with your gear! For example, a spell's accuracy would look the same without any boosts, but with boosts it'd display the actual accuracy on the card in green instead of yellow. If the card has no boosts, the accuracy text stays yellow, but green when a boost is applied. For damage, maybe just change the text (no real need for colors to change).
Overall I think it could be a neat toggable feature for those that want to easily see the impact of their gear in battle. It'd also help predict how much damage/healing you'll do (We've all had those times with enemies surviving with under 10 hp). What do you guys think?
