Alright, Imma explain this in a way you shitters can understand. There are several types of immortality.
Immortal until killed: These are the ones where old age means nothing. Elves, vampires, and deities fall under this category.
Immortal until natural death: This is kinda the opposite of the first. They won’t die until they perish from age or some other natural cause.
Immortal hive mind: This is just a collection of creatures with a hive mind, so while you can kill the body, you can’t kill the mind.
Immortal under special conditions: These are like the immortals until killed, but you can only kill them in special ways. Think liches, Baldur, etc.
Immortal only in name: Sometimes immortal is given as a title to those who are extremely hard to kill. A title for a warrior like “Qentyl the Immortal” or some shit.
Immortal reincarnation: This one is pretty self explanatory, if they die, they come back as someone else.
Immortally returning: These are the ones who can be killed, but always come back. The best way to describe them is like the perpetuals in Warhammer 40,000. Vulkan and the like.
True Immortals: These are the worst immortals. These are typically the ones we think of when we think immortal, but we often do not think of the full ramifications of being a true immortal. A true immortal never dies, be it from natural or unnatural causes. Age will not kill them, nor will anything else. These are the ones that will outlive the heat death of the universe (look it up, it’s kind a scary). This is a fate worse than death.
Idiots: The idiots that confuse immortality and eternal youth. They are not one in the same.
True immortality is not as bad as it sounds, as long as you have access to multiversal travel.
Since I can auto-regenerate:
I’m basically an immortal who could only be killed in specific conditions.
Fire and lasers
Nah, that’s just being a troll. Like, that’s the weakness of a troll.
