An Adventure's End
Every adventure comes to an end. When the end comes, Devotion returns to 1, and heroes consequently return to all the limits of that rank (aside from whatever PAs or IAs they have gained). Players may opt to choose different starting ranks for their hero's Abilities and Skills. In addition, new Techs may be created for use if desired.
If you're using the optional War Forms rules, then players can opt for different starting ranks for their Forms as well.
