Really dependent on which mythology's dragon you become. That aside, being a dragon in modern day would probably be very hazardous. Better hope you're a small enough dragon to not cause much property damage while figuring out your new body, and to stay mostly undetected, because otherwise you're likely to end up dead, or in captivity somewhere in fairly short order.
Assuming D&D lore, polymorph fixes that problem pretty easily. A polymorphed dragon could blend into society pretty well, and if you want, you could still get a ride into international waters (to avoid setting off national airspace warnings), fly down to some random jungle tribe, and be worshipped as a god. Plus nigh immortality (assuming aging only affects your polymorphed form and you continue to age at the rate of your dragon-self).
Instant death may be useful if it’s like the Death Note, or else you’d also just get arrested.
At some point an investigator figures out that you're the only person that's connected to all the deaths, however remotely. As the years go by, you've done lunch together a few times and are on a first name basis. Their efforts are fruitless, and they can't prove anything. But now you have an FBI surveillance van permanently parked outside your home, and that investigator keeps coming around.
Except now you're wracked with crippling guilt every time you mow the lawn, chop up veggies for dinner, or walk by some poor little scrawny weed growing out of a crack in the sidewalk.
Ok thats a half empty glass of sunshine if I ever saw one. How you guna spend your time conversing with something that'll live less than a year, shit out a bunch of seeds, then die? Why not find out what the Oaks, Cypresses'ses', Hemlocks and Maples have to say about the day America was conceived, birthed, crawled, walked, flew, first fuck last fuck. Shit I'd retire and walk the trails listening to stories from something that has expierienced 3 life spans.
Except plant never developed language or even neurons to process thought. You drink the "Talk to plants" potion and the world is just as silent as it was before.
It would also cover strength. And courage, considering you're a freaking dragon! And depending on the type of dragon, poison breath could be covered too.
I think the sleeper is "talk to plants". Remember how Aquaman used to be the joke in the Justice League? And I'm not well versed in comics, but Poison Ivy comes to mind as being pretty powerful.
Nah, if anything talk to plant is pretty weak. Poison Ivy can control plants, which is significantly stronger. Control plants let's you force them to grow big and grapple people, or produce particular toxins in people's faces, etc. Talk to plants lets you ask plants very politely to do something, but they are still just normal plants, and can just say no.
DM here. Note that this is "talk to plants" and not "tame/control plants." BIG difference. You basically just add "plants" to the languages section of your character sheet, and I have to figure out what accents ferns, oaks, and grasses have.
