However it is worth noting that the spell also says the condition to end the spell must be something the DM agrees to AND is likely to happen in the next decade. So it won’t be a cakewalk to be suddenly immune to aging.
The first part is hard, but 9.5 years passing is guaranteed to happen in the next decade.
I’d say since spells work the way they do, they always use the relative frame of reference of the caster when cast and the relativ frame of reference of whatever it affects when counting the duration.
The method here would be to make it something like “9.5 years elapse from the prisoner’s perspective” while sticking the prisoner in some environment where time passes more slowly for them. Do you remember the wave planet in Interstellar and how they spent a couple of hours on the surface, then when they returned it had been twenty years for the crew member that stayed behind? We’re looking to exploit that, so we stick the prison in a extremely high-gravity environment or on a ship that’s moving at ludicrous speeds
That’s quite a funny gamble to take, actually. The chances actually are slightly in your favour for getting extra time (if you average enough trips out, you get about 15% more time spent in the Feywild) but with any individual case your 9.5 years could go anywhere from several millennia to less than three days
Edit: realised my maths for the 15% will be a bit off because I forgot that D&D uses a 10 day week, but I don’t think it will have hugely affected the results
The problem is that you only roll once they leave the feywild. Up to that point time between the two planes works in sync. You effectively just time travel when leaving depending on the result of your roll.
Ahh, true, so it wouldn’t help if you intended to return to the prison before the 9.5 year term was up. You’d need to instead wait for your prisoner to get out and return from the Feywild themselves, in which case it potentially buys you more time to prepare but may backfire
There’s a 5% chance that days become years. Based on just that alone, for every 20 days spent in the feywild you’re missing a year in the rest of the world. I got a factor of 22.7 on average for a 7-day week, and 23.3 if it’s ten.
jounniy is correct that the chance for a time warp is only rolled once when you leave the Feywild rather than each day spent within it, which is why we’ve got such different numbers (at least, in the current 5E DMG)
9,5 year for whom in whose decade? 9,5 years for you in your next decade? Guaranteed to happen. 9,5 years for me in your next decade or for you in mine? Not guaranteed.
‘Yes but this planet is on a much longer orbit and its [time it takes to orbit] is the same, so it must be moving much faster then the one you’re teleporting to, where…’
I wholeheartedly disagree. The passage of time within a given frame of reference is an objective fact. Relativity existing doesn’t negate objectivity. If anything, it makes the gathering of objective evidence and reference points more necessary.

Depends how gonzo you get with the fantasy, the setting’s cosmology, and whether your gm is an engineer who does relativity math.
I’d say since spells work the way they do, they always use the relative frame of reference of the caster when cast and the relativ frame of reference of whatever it affects when counting the duration.
So it’s not certain that 9.5 years will pass in the next decade, if you do relativity shenanigans?

Feywild would be possible but by RAW the time difference is only calculated once you leave the feywild.

“Subjectively true” is really the only kind of true anyway.
