Debating on weather or not to skip G1
Don't.
Skipping G1 will make the next generations considerably harder.
Example - In G3 statue restoration, you have to do a normal run of every dungeon in Uladh.
HOWEVER, if you didn't skip G1, Peaca and Coill clear right away. Just drop the pass, watch a short cutscene, and go out.
If you did, they're one floor long.
Coill isn't bad, but Peaca is. Everything has at least a couple thousand health and very high defense, anything with magic has chain casting, blue ghosts have thunder, red ghosts have fireball, hollow knights have arrow revolver, and a few more things. I'm not sure how long the G3 one is, but it's still difficult, if not impossible, if you don't have a very powerful guild/friends with a couple hours to spare. When I went on a normal run with my guild for fun, all 3 floors took about 9+ hours, even with the several level 600+ people.
And you miss a huge chunk of the story line.
Don't skip. Just join a powerful guild, get well know by talking, or helping guildmates with things, then see if they'll help you.
Or do what I did. Have a powerful friend and his very powerful friend help you.
