Caustic Void
Source
Starfinder Enhanced pg. 68
You can transform the crushing force of a black hole into a more caustic destructive energy. You can use this revelation when forming your solar manifestation to change the manifestation’s properties. If your solar manifestation deals physical damage, this revelation grants the manifestation the effects of a corrosive weapon fusion; this temporary fusion ignores item level requirements and doesn’t count toward the maximum level of fusions the weapon can have at once. If your solar manifestation deals only energy damage, this revelation causes the manifestation to deal acid damage instead of any other energy damage types.
If your solar manifestation provides a bonus to AC, it also grants you acid resistance equal to 5 + half your solarian level. A solar shield manifestation applies both the corrosive weapon fusion effect to unarmed attacks with the shield as well as the acid resistance effect, though you only gain the acid resistance benefit while your shield is aligned, whether or not that acid damage is dealt by your target.
