As an action, you can create a vial of liquid with fur suspended in it. A creature can drink the contents as an action to alter their physical form to gain different characteristics. When you use this ability, you have 1 catalyst to choose one or more of the following effects. Each effect has its own catalyst cost, reducing the pool of catalysts.
Bear’s Endurance (1 catalyst). You have advantage on constitution checks and gain 3d6 temporary health, which is lost when the spell ends.
Bull’s Strength (1 catalyst). You have advantage on strength checks, and your carrying capacity doubles.
Cat’s Grace (1 catalyst). You have advantage on dexterity checks and when calculating fall damage, reduce any falling distance by 4 meters if you aren’t incapacitated.
Camouflage (1 catalyst). Your skin and equipment take on the color and texture of nearby objects, including floors and walls, masking you from detection. For the duration, you have advantage on Stealth checks.
Echolocation (3 catalysts). You gain the ability to sense your surroundings by sound. For the duration, you have advantage on Perception checks that rely on hearing and have blindsight out to a range of 5 meters. If you already have blindsight, its range increases by 5 meters. You can’t use this blindsight while deafened.
Keen Sense (1 catalyst). Choose eyes, ears, or nose. Your senses connected to that choice become more sensitive. You gain advantage on Perception checks that rely on hearing, sight, or smell.
You can increase the pool of catalysts by 1 for each additional catalyst expended.
