Capstone enhancements

Overview
Capstone enhancements are enhancements selectable after sticking exclusively with one class for 20 levels. A character can train only in one class Capstone at a time. Multiclass characters are not eligible for capstone enhancements because their levels are split among several classes, none reaching level 20.
