Alchemist Research Field: Mutagenist

You focus on bizarre mutagenic transformations that sacrifice one aspect of a creature’s physical or psychological being in order to strengthen another.

The mutagens flowing through your blood have altered your body chemistry. When you roll a Fortitude save while affected by a mutagen and dislike the result, you can end the effect of the mutagen to reroll the save. This is a fortune effect.

When you drink one of your field vials, you also gain resistance to physical damage for the same duration. The resistance is equal to half your level.

If you imbibe another mutagen while you are under the effects of a mutagen, you can gain the benefits and the drawbacks of both mutagens at once, despite the fact that they both have the polymorph trait and would not normally function together. If you come under the effects of any further mutagens while benefiting from two mutagens, you lose the benefit of one of the former mutagens of your choice, while retaining the drawbacks of all the mutagens.
