Since you are undead, you are immune to the affects of ageing, and can potentially "live" on forever.

Revenants tend to be chaotic in nature due to their need for vengeance above all else. They don't tend to sway towards good or evil though.

Revenants are most commonly human in origin, due to their sheer willpower to bring them back for vengeance. They can have origins from other races, such as half elves, half orcs and the like, but even rarer are the smaller races. Due to their kind-hearted nature in life, it is rare to find one with such a need for revenge in undeath. Your size is medium.

Your base walking speed is 30 feet.

Thanks to your undead nature, you have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.

You have advantage on saving throws against being poisoned, you are immune to disease, and have resistance to poison damage. Additionally, you do not need to sleep. You must remain in an inactive state for 4 hours to gain the benefits of a long rest. You are aware of your surroundings while in this state.

You can speak, read, and write Common, and one extra language of your choice, preferably of your origin race, or a language you would have known in life.

When you drop to 0 hit points, you can choose to stay conscious. If you do, you gain temporary hit points equal to your character level, and while in this state, you can only take an action or bonus action on your turn. You make death saving throws as normal, and go unconscious after you fail your first death saving throw. You cannot use this feature again until the next dawn.
