How do spell-induced modifications to Fortitude affect HP, during spell's duration and after? - Waffle boy (As channeled by Nobody)

For players, it alters your current and maximum hit points. When it goes away, you lose or gain that many hit points.

For monsters, you figure out what half of the monster's challenge range is, rounded down. That becomes its level for determining Fortitude changes. So for instance, a challenge range of 4 to 9 has a midway point of 6 when rounded down. I'll often just eyeball the changes when it comes to monsters, but that's the formula for when it's important. - LR
