Okay I will reveal a little bit of planned minor gameplay changes, nothing major yet. The crusader scepter allows you to use crusader abilities without wearing the respective armor. It will cost gems however, here are a list of gems and the respective crusader ability they allow for. You can even place an elemental augmentation on the scepter for more flexibility.

Gem	Ability
Diamond	Attack
Emerald	Support
Redstone	Shield
Amethyst	Debuff
Glowstone	Spirit Steal (Allows you to use a spirit as a missile causing it to explode or you can sacrifice it to regain your health if overcharged)
Nether Quartz	Target (Allows you to target an enemy, paralyzing them and can regenerate the health of your spirits if you don't have nymphs, or you can use it to stunlock an opponent temporarily)
Blaze Powder	Charging it allows you to buff your spirits, overcharging it creates an explosion depending upon the element of the scepter)
