So, Keith Baker invented my fave official game setting, the amazing world of Eberron, and within that, one of my favorite races, the Warforged. So, with 5e, I decided to make up some stats for PC Warforged, and came up with the following. Today, Mr Baker published his own stats, and I have to say, apart from a few differences, they are pretty similar. See what you think!
Ability Score Increase: Your Constitution increases by +2
Speed: Base walking speed of 30'
Living Construct: A warforged gains advantage when saving against necrotic damage or effects that would put them to sleep. Necrotic damage against them is also reduced by an amount equal to their Constitution modifier +1. They are immune to Exhaustion and Poisons, and do not need to breathe. A warforged gains the benefits of a short rest after only 10 minutes, and a long rest after only 4 hours. Warforged only recover half as many hit points when receiving healing spells. They do not naturally heal all damage after a long rest. Warforged are considered to be both Humanoids and Constructs for the purposes of effects.
Machine Stability: When reduced to 0 or fewer hit points, a warforged automatically stabilises, and does not have to make death saves. They can still be killed by being reduced to minus their bloodied value (half total hit points) or more.
Mantled: Bludgeoning, Piercing and Slashing damage against the warforged are reduced by an amount equal to its Constitution modifier (minimum 1). It has a natural AC of 12 + Dex Mod, and when hit by a critical hit, has a 25% chance of reducing it to a normal hit.
