Felghana the home of our bestfriend Dogi. the one who keep rescuing us on Darm Tower at Ys1.

combat mechanic from Bump Mechanic just turned hack n slash now.
plus more and more on Bullet Hell with the Magic projectiles.
bosses are still challenging as always.
Adol can only wield 3 magic Bracelets

They have Voice actors now, tho this one is only English, Chester's voice really into it. as expected from EN VA of Frieza,
Adol on the other side brought his Narrator with him since he is still a silent protagonist and nodding is only thing he knows for communication.
Sister Nell is ASMR to listen.
but Cynthia. OH BOI, i did bought her entire stocks ( ͡° ͜ʖ ͡°)
Elena.. happy or sad. still same tone of voice.
Dogi is just Loud
--
tldr;
Oath of Felghana is just awesome. Adol still a pervert

It was a quick and fun game.

This game's great! If you're a fan of ARPGs, it's a straight-forward game with great graphics, music, game-play, and it's fairly short. There's a remaster coming out soon (on console at least) but all it adds is voice-over and some QOL stuff (rewind, etc). Of the Napishtim-era Ys games, this is my personal favourite.
