I've got a couple ideas for Spiral Knights. One is an idea that will improve the player experience and the other is a new idea for an achievement.
1. A more detailed character screen. This screen would include bars that total the defense values of your equipment.
2. A new Achievement called 'Long Lasting Freshness.' It is earned when a player carries a large Crimsonite crystal (I.E.- a Big Red crystal) out of a stage.
In the inventory screen, if you mouse over the icon at the bottom that looks like your helmet, it displays your cumulative defensive stats, as well as any bonuses your armor grants you. Mousing over the weapons shows you any damage, ASI, or CTR modifiers contributed by your weapons and armor.
