Immortality is kind of awesome, especially how it's done in mage errant.

Unfortunately it kind of has a major downside in that the liches are pretty much stuck in one place, except kanderon, but even she's not absolutely immortal since the star in her core would eventually die and her along with it(unless her stellar affinity keeps that from happening somehow) of course she could live for billions of years so yeah

However what I want is an affinity, more likely a list of affinities that could in theory make you absolutely immortal, like cold mind level if that even possible, or at least close enough

My ideas: ○A human affinity(or other species specific affinity) to augment their body and make possible even grant biological immortality, maybe even reverse aging like the immortal jellyfish can do

○Mind/dream affinity: A lot of people myself included once upon a time thought that immortality would be awesome, but I forgot to take into account that our brains are like computers and computer eventually run out of space, I actually checked the average human mind has around a petabyte of storage so it could hold around 400 years worth of knowledge, after that I don't know.

liches here have the advantage since their minds are actually aether constructs so I assume they don't have that problem, but what kind of affinities could help work around that problem

My best guess something like mind/dreams affinities to create some kind of mental constructs to help out thinking and storage capacity, I think I remember reading something like that in the books but it was years ago

○Now something to help deal with the boredom, when you live for so long so got to have something to do or you'll go crazy, for this one I'm drawing a blank

○Now onto making you damn near invincible in a fight, as our deal Talia would say the best solution to a problem is to burn down to the ground, and I agree. My best ideas for a list of affinities that could make someone invincible would have to be: force, planar, and possibly some kind of energy affinity if it exists, and if energy doesn't work then vibration

•force is basically telekinesis if you think about, you could create weapons made of pure force that could cut through anything •planar could essentially make you like gojo, and with the brain enhancement, you might be able to pull it off in actual battle •energy if such an affinity exists but it might, since there are so many types of energy based affinities it should in theory, and why? It's simple, energy is literally everything, kinetic,chemical,thermal, maybe even nuclear, there is literally no limitations to what it could do if it exists, there might even be some matter manipulation shenanigans possible if my understanding of physics is correct(probably not though since I suck at it) •and if energy is off the table then vibrations, since again so many possibilities

Any thoughts? And if so what would be your list of affinities that could make you absolutely unkillable and immortal
