Allomancers have the ability to Burn (or use) metals that they have ingested, in order to fuel a variety of physical and mental enhancements and abilities. There are 16 metals that Allomancers are able to use, each providing a different effect. All these metals must be pure when ingested, and the alloys must be mixed to specific proportions.

Metal Mixing

You gain the knowledge of four Metal Mixtures, the precise ratios required in an alloy, and the ability to craft vials using liquid of your choice mixed with the metal agent. The required volume and proportion of metals for each mixture is detailed in the mixture description. Your DM may alternatively allow you to simply spend 5 gold per vial, without requiring the metal in your inventory.

At the end of a long rest you may mix up to four vials, if you have enough empty vials to store them, each of which may be any mixture you know of. Each vial weighs half a pound. By using the Use an Object action, you can consume one vial of metal which can be Burned at a time of your choosing, requiring no action. You may ingest as many mixtures as you wish, however ingesting more than one vial of the same mixture causes the first vial to become inert and useless.

Once you start Burning a vial, the effects last up to the metal's duration. You can choose to end the effects early, requiring no action, however this causes the remainder of the consumed metal to become inert and useless. You may Burn one metal at a time.

At the end of a long rest, any metals which have been consumed are destroyed by your body.

• As an action, You create a bubble of faster time in a five foot radius sphere centered on your position, although it cannot be moved. Creatures fully inside or outside of the sphere may not move through the boundary of the sphere. If a creature is partially inside the sphere, it is affected by the faster time unless it moves outside the sphere. The boundary counts as three quarters cover for the purpose of attacks, which cannot be ignored by any feature.
• While within the bubble, events outside seem to move at a crawl. Any affected target's speed is doubled, it gains a +2 bonus to AC, it has advantage on Dexterity saving throws, and it gains an additional action on each of its turns.

On its turn, it can use either an action or a bonus action, not both. Regardless of the creature's abilities or magic items, it can't make more than one melee or ranged attack during its turn. If the creature attempts to cast a spell with a casting time of 1 action, roll a d20. On an 11 or higher, the spell doesn't take effect until the creature's next turn, and the creature must use its action on that turn to complete the spell. If it can't, the spell is wasted.
