Gave the ring to the school, the game was fun.
I don't know if there's a way to destroy it, didn't deal with the wereslime and did nothing with the broken dagger (these two are linked?), also not sure you can press the button in Castle Stodthon.
I think the Wizard's cape and Mera's shroud are bugged, they significantly lower the MPs. Also when you talk to the Archmage you must be careful that your following characters are behind you and not on the left or on the right, otherwise the pumpkin guys can't come and the game is stuck. Finally I could swear the guy in the swamp did not give me the 5000g he said he did. I've not investigated any of these deeper though, maybe I'm inaccurate.
The game is very polished anyway, with all those characters which come or have new things to say (with a reward) as you've accomplished things, and a little story choice here and there.
I played the game because of full party creation, I'm always ready to play one more game with full party creation. The open world is a big + too, the game would not be half as good without it.
Combat is fun, balance is on point and, on top of getting aside the road in the beginning to fight monsters which would drop much better pieces of equipment that what you currently have or can buy, there are quite several powerful unique items which are satisfying to find. You definitely have a bit of different choices of equipment at the end, there's more than just one obvious choice.
Good job, thanks for sharing.
