+D6 for surviving the battle (replaces +1 from scenarios)
+5 per wound hit (replaces +1 for Out of Action)
+1 for taking a Leader/Champ out of action (same as standard)
+10 to winning leader (if new scenario has this type of bonus)
+1 for rally (same as standard)
+1 for killing an enemy (same as standard)
I know some scenarios doesn't give +1XP for surviving the battle. Other scenarios can in fact give additional +1 for surviving the battle or taking enemies out of action. We pretty much ignore that, keep it simple and apply D6 XP for any scenario regardless.
