One other thought on this*, we're talking about a magical world. One of the posters complaining on the other thread talked about how a dracolich just flew around helplessly while the party rested for 8 hours.
I was thinking about this one and I gotta say, huh? If the dracolich is in their lair they have lair actions. Things they can do every 6 seconds. Options vary by dragon, in most cases the effects last until the next lair action or the dragon dies.
- Black dragon has impenetrable darkness to set up other stuff.
- Blue dragon just collapses the ceiling on the party.
- Green dragon can use grasping vines but it doesn't really say how tall they are. I'd say they spread over the dome but if they don't there's just surrounding the hut with a wall of thorns.
- Red dragon causes geysers of magma bury the hut, if not just fill the hut with magma (depends on a couple of factors depending on how you rule).
- White dragon buries the hut in shards of ice that continuously fall from the ceiling, uses a wall of ice or just obscures sight with fog.
If the dragon wasn't in their lair, why stick around to fight?
But what really bothers me is that the poster never asked how other people would deal with something like this. It was just given as an example that because they didn't come up with a counter at the time. It was fait accompli, the spell is just impossibly broken and the party can
always get a long rest whenever they want.
So yes, some of my options were a bit out there. But this is a world where mods have fire giants with cauldrons of molten metal lying around at their disposal. One invisibility spell and the hut will potentially be encased in molten metal. With a lucky roll the giant might even get away with the party not knowing it's going to happen before the metal starts spreading. But of course that would be "impossible". Which if you were fighting CR 1/4 goblins it would be. Possible counters depend on the opponent and the situation.
P.S. I should have said "obscure sight" instead of "paint". Good grief, take one option overly-literally and assume that suddenly every orc on the planet is carrying a 10 gallon bucket of paint is stupid as evidence there's no possible way to counter the spell.
