Feels like progress is sloooow now, I started class changing my guys around finally in the early 20s, Seems like the short term power loss is quickly offset by the much higher HP you'll get due to levelling back up faster. Once I've done it a few more times too the extra skill slots should make it not a big deal - My original Knight should be able to have literally every relevant skill, for example. I'm not entirely sure where I should be progressing at this point. I need some kind of emblem/key to go farther in the underwater zone, I've finished everything in the Mausoleum of Flames besides the fire salamander or whatever, which is 5 stars so I'm not going to bother. I can't kill Murderall, and I went down to the stone in the Ghost City and was told the spider queen would destroy me.
Basically, right now I've got a map complete water zone, an unexplored ghost city third level, and a map and lineage clear (basically) fire zone. I'm 3/4 stones for my next Divinity upgrade, hopefully once that's done the plot will push forward a bit
I like it best when I've got real options on where to go. I have a LOT of lineages left in the Sea but they're just not spawning when I'm down there and it's a real trek back out every time since the closest stone is up in the palace (and I have to run any time the golden asshole knight spawns there).
