Invest In the Energy Charge Skill
Upon starting Dragon Ball XenoVerse you may have noticed that something we’ve all come to expect in our move sets is missing. That is the ability to charge up your ki to keep you powered up and ready to dish out some serious damage. But, when you start the game the only way to charge up is by inflicting or receiving damage, unless you’re an Earthling in which case you can also patiently wait. But sometimes you don’t want to wait a long time or enter the fray without having some specials ready to light up your adversaries.
It turns out there is in fact a charging skill available, you’re just going to have to either purchase it or learn it. You can find it at the skill shop at the beginning of the game for somewhere around 2000 Zeni. It’s a very useful skill that allows you to quickly charge up your ki whenever you’re in the clear. There are several versions of the skill with varying levels of efficiency, but the one you are able to access early in the game should be more than good enough.
