The DMG says that time does not pass on the astral plane, so my players were in the middle of an adventure where time was an issue. After many battles they were in need of rest and spells, so they plane shifted to the astral plane on the assumption that when they returned it would be at the same moment on the material plane. (of course they had to teleport to the correct location upon their return)
I ruled that while they were on the astral plane they could rest and meditate/pray for spells, but any other class abilities that reset on a day by day basis would not reset.
My question is, did I handle this correctly? Would the spellcasters be able to rest eight hours? Should I have let the other abilities reset? Any feedback would be helpful.
Time passes on the Astral Plane. You don't age. When you leave the Astral Plane, all the time you spent there catches up to you. If a human spent 600 years there and left, he would crumble to dust.
So when they plane shifted, the fight they were in ceased and the bad guys scratched their heads, wondered where the opponents went, and then carried on with their nefarious deeds. When the party returns, the Material Plane will have passed as much time as they spent on the Astral.
However, they should be fully capable to rest and recoup and regain all abilities, including daily use limited class abilities, spells, and nightly healing.
