Item: Hydra Mutagen

Alchemical: Alchemical items are powered by reactions of alchemical reagents. Unless otherwise noted, alchemical items aren’t magical and don’t radiate a magical aura. Alchemical creatures are partially powered by alchemical reactions.

Consumable: An item with this trait can be used only once. Unless stated otherwise, it’s destroyed after activation. Consumable items include alchemical items and magical consumables such as scrolls and talismans. A character can Craft consumable items in batches of four.

Mutagen: Mutagens are a special type of elixir that temporarily transmogrify the subject's body and mind. Typically, only alchemists have the expertise to craft mutagens. A mutagen always conveys one or more beneficial effects (listed in the Benefit entry) and one or more detrimental effects (shown in the Drawback entry). Mutagens are polymorph effects, and a subsequent polymorph effect attempts to counteract an existing effect; the counteract check for a mutagen uses the item's level and a modifier equal to that level's DC – 10.

Polymorph: These effects transform the target into a new form. A target can't be under the effect of more than one polymorph effect at a time. If it comes under the effect of a second polymorph effect, the second polymorph effect attempts to counteract the first. If it succeeds, it takes effect, and if it fails, the spell has no effect on that target. Any Strikes specifically granted by a polymorph effect are magical. Unless otherwise stated, polymorph spells don't allow the target to take on the appearance of a specific individual creature. If you take on a battle form with a polymorph spell, the special statistics can be adjusted only by circumstance bonuses, status bonuses, and penalties. Unless otherwise noted, the battle form prevents you from casting spells, speaking, and using most manipulate actions that require hands. (If there's doubt about whether you can use an action, the GM decides.) Your gear is absorbed into you; the constant abilities of your gear still function, but you can't activate any items. You lose your Speeds and gain those of the battle form. If a polymorph effect causes you to increase in size, you must have space to expand into or the effect is disrupted.
