I went to the slope at X-30 , Y-23. I got ammo extension and ammo refund and had full ammo energy so the crystals are not giving me the red energy when I shoot them. But if I use 1 red energy to fire a Force shot and fired my normal weapons at the crystals to fill up the empty red slot + getting "ammo refund" I can get one Overcharge shot without buying the Overcharge upgrade lol I think I broke it.
