Leveling Up procedures have since been simplified. My previous response is no longer needed. :)
Hello, thanks for your feedback. I may have done a poor job wording the rules. Perhaps I need a revision with clearer language. Let me attempt to clear that up.
When a character reaches level 3, they would roll 3d6 and that would be their new HP total if it was higher than their current HP. They would NOT be adding 3d6 to their current total.
Say level 1 they roll for starting HP and get 4 HP.
Level 2, they roll 2d6 for a 2 and a 5. Their new total is 7 HP.
Level 3, they roll 3d6 for a 4, 5, 4, for a new total of 13 HP.
Level 4, they roll 4d6 for a 2, 2, 4, 1, for a total of 9 (then, because they rolled lower than current total, he would increase by HP by current level (4), so the total would be 13+4=17 HP.
These are really just guidelines. Another way you can handle it is just letting a character add 1d6 HP every time they level up and that's it. It's simpler and will keep HP lower if that's your desire as Warden.
Re: Fortunes table, it's on a spread, so the d12 indicator is for both mishaps and fortunes as the table spans across the total length of the spread.
Hope this helps.
