Comments of chapter undefined of Immortality...what's that? Can you eat it?

for the abilities I like the bracket look, and I like the term marking more than runes, runes just seem overdone, as for the arm, wound't another option be hard light so in a pinch he could morph it into a blade and stab anyone or even skewer his meat onto it, I do like the space bending idea aswell, ohh if he gets advanced enough would he be able to like shape space into a bow and use hardlight/laser arrows, also cause he could bend space to give it solid form would that mean he could make it into a platform to stand on in the air, and walk in the air aswell
