The 6th spell level Flesh to Stone is the lowest I could find - also it lasts 1 minute. Prismatic spray could also do it, but it's super random to say the least.Would it be possible to turn the dragon to stone and then turn it back upon arrival?
Maybe if you hired a cadre of 3rd level enchanters...Enchantment specialist wizard's Hypnotic Gaze and a lot of caffeine. As long as he continues to use his action, he can keep that puppy going forever...
It has a terrible Wis save (+0) but getting a 5th level scroll would be hard enough, and that only lasts 8 hrs. Still, it could help make the creature fail additional, other saves - or skill checks, like a bluff check?Depending on the Dragon's Wis Save, something as simple as a Bestow Curse spell could incapacitate a Dragon or facilitate its incapacitation by imposing Disadvantage on specific saves. When cast as a 5th level spell there is no more Concentration and increases the duration. It can be cast multiple times to really shut down a monster. One Remove Curse spell will remove all of the Curses.
Ha, nice perspective!But up until that point, I'd embrace the fact that a whole four-hour session will consist of the players arguing over the best plan, so I wouldn't have to do much prep work, and probably everyone will be having a lot of fun.
Yeah, this is probably the best type of solution - "just make something up!" But that works better from the GM's side than the player's side. Still, that's a great idea, and I will likely try to have something like this ready for them if it's not turning out to be fun.Homebrew a version of sleep as a ritual that requires more than one caster. It will knock a creature out for a day.
Ok, here's my idea:Homebrew a version of sleep as a ritual that requires more than one caster. It will knock a creature out for a day.
