I made energy swords in 3 flavors: Electric, Fire, and Plasma.
Every living thing and even some non-living things in Farsiders have "Spirit"(Mind, Body, and Spirit), which from it, is born one's elemental energy.
My elemental chart looks like this right now, energy swords are really effective with anything from the Aether category, and half of the Nether category(Plasma and Water swords). There are a different set of swords that are similar called Spirit Swords, except they only have a hole with no gem, and useable with any element, even Metal and Ice. Also, Molten is Lava/Magma basically, I was gonna name it Lava, lol. :catthinks
The differences should be apparent, for example "Void" is related to Hex and Darkness, it would be like a solid dark sphere of matter, while Darkness is more ethereal and energetic and Hex is somewhere in between.
Then, if one's power becomes high enough, they are able to attain one of the three transcendental traits: Such as time manipulation, so it's around that point people get hax abilities on top of they're elemental powers and other abilities.
MIND has it's own chart too, but not exactly an elemental one, lol. But theirs different types of psionic energy though. Think telekinesis, pyrokinesis, cryokinesis, and other psychic abilities. For example, somebody with spiritual fire won't be able to hit a pyrokinetic since they'll be able to defect flames that get thrown at them and if specialized entirely in pyrokinesis, manipulate the flames themselves. Although, I'm still working on the MIND aspect of things. For example, be kind of limiting if pyrokinesis could only manipulate flames and nothing else, so it can also generate fire out of nothing but it's own energy, especially manifesting a distance from the user unlike with regular Spiritual Fire that must be emitted from the self.
Things like premonitions, sensing with the mind, telepathy, those are all separate, just like how in Body, sight and hearing are completely unrelated to how durable or strong somebody is.
BODY is simple to understand, it's things like super strength, super speed, insane agility, ultra-durable skin, the list goes on, and how it is varies from person to person, such as somebody that can tank explosions, but can't carry more than what a normal human(oid) can, or a guy that can lift 30 tons, but would get hurt by the same explosion as the tanking guy, lol.
