We made it through the adventure set up. :)
Last week we created a party of level 8 characters, including a gnome thief, human fighter, human cleric of the True, and an elf mage. (The gnome is the only one with a name so far: Cinnamon per Kira's tradition of naming her characters after herbs and spices.)
I got a cleric to 7th level in the previous edition. It took years because I mostly played her in tournament adventures. I've never been in a group that lasted long enough for the characters to get past 4 or 5.
Reaching high levels is one of those things that happens to other people, not me. It turns out that a level 8 mage is...powerful. My spell list is fantastic. And that's just at level 8. Face asked for a level 10 version of the PC. Now she can cast...hehehe...Fireball.
