The VOIDRUNNER'S CODEX is coming! Explore new worlds, fight oppressive empires, fend off fearsome aliens, and wield deadly psionics with this comprehensive boxed set expansion for 5E and A5E!
I mean, it seems like a prerequisite to get to play in a very specific campaign. It doesn't seem like something that will benefit your character in the there and now. If it also made you immune to "save or die" spells, then that would be something.
Why? Very few campaigns are going to last hundreds of years. And very few monsters have age effects.
I have only killed PC from age effects since 1980. A solution looking for a non problem.
