1. Modify, unless you mean resetting after the scenario back down to 15, no I did not modify.
2. No. I did not add in any one. I started with all 6 from the beginning, but of course, I was given Kyra and Merisiel originally.
3. K, M, Valeros, Ezren, Lem, Seelah.
4. I don't remember. I want to say yes. I've died too many times. I'm happy to wipe and restart with same group, if that will help.
