does anyone know the confirmed number of dragons in the game i know there are 6 types but is there only a given amount of dragons or are there endless amount so you can always fight them?

4 Plus Infinity!

Endless amounts, even after the game is over, Beth has confirmed dragons stick around after the MQ, they just don't show up as much

I have a much more superior answer to my friend Edgar's reply.

They are endless.

They said you keep fighting dragons after the main quest so its endless, but not often, don't expect it to be raining dragons or anything, it will be that rare epic battle that comes along every once in a wile.

They're handled the same as a regular creature, so they will spawn endlessly, just like any other creature.

so they always respawn so you wont run out of souls ok thats good i thought there were only so many so you can only pick and choose the shouts you want to upgrade

Thunder dragons!
