The Everchanger changed.
This was not an unusual observation in itself. The expert hero mech frequently altered his more subtle characteristics by changing his glow.
If he wanted to focus on ranged combat, then he would switch to the Illustrious One. The design spirit was able to make his relatively weak Vitalus rifle luminar crystal rifle inflict considerably more damage than usual.
If Joshua wanted to increase his hit rate and strike at targets far beyond his normal range, then he would channel the prophetic capabilities of Ylvaine.
If he wanted to break through pesky transphasic energy shields, he would tap into the power of the Phase King. This happened a lot more often as of late.
While Joshua most definitely formed a list of favorites, there were no useless design spirits as far as he was concerned.
