After another successful online D&D session, I again revisited my character and how he did in the adventure.
My biggest problem was with paladin spells, my character cast 3 and failed on 2 (Command, Compelled Duel) while one resulted in nothing significant (Detect Magic).
So I went and redid the prepared spells for my character.
I dropped Command and Detect Magic, and added Heroism and Searing Smite.
Hopefully Kal Jadestone will be more effective in this next adventure. His bear companion Zod has played better than he has.
