Let's Play Ys 8 Episode 76: Valley of Moderately important officials
1Welcome to the Valley of Kings don't bother fighting any enemies here other than the bugs because you cannot kill them until you get the purifying bell.
I will say the music here is quite good and the dungeon has some pretty neat design but I roughly know the route so it isn't too difficult for me.
Then you get the purifying bell... and the dungeon music conveniently stops.
Yeah it's not any major surprise but the mid dungeon boss fight is here and I don't believe you outright have to equip the purifying bell against it but you will for everything else so consider equipping the dang thing.
The Doxa Griel itself isn't necessarily an easy boss but also not too hard of one either. It's probably most comparable to smelter demon from dark souls 2.
After that we warp back to Castaway village to have our next bonding event. This time with Quina. Overall it's pretty sweet.
