MH Oldschool

I got the go ahead from Grender so I'm putting this here!
There's a ton of info on this site that I thought might be useful for anyone starting the game or wanting to figure out builds and stuff!

If you know any other sites or have any documentation of your own for the game, feel free to leave a comment with it!

Kiranico is pretty much the go-to database for all things Monster Hunter in MH3U and later. I prefer not to use databases like this as I progress, so I don't usually reference it, but when I'm doing research for other projects, it's a godsend.

I have been told this one is better for MH:Rise in terms of data and values
