Your Strength score increases by 2, your Constitution score increases by 1. However, your Dexterity score reduces by 1.

As a construct is a machine, be it magical or mechanical in origin, you are unaffected by a number of afflictions that might damaged an organic being.

• You are immune to poison damage and have resistance to slashing damage.
• You cannot be healed by most healing spells, and must instead by repaired with metal.
• You do not need to sleep, eat, or breathe.
• You cannot swim. If you are submerged under deep water for more than 15 minutes, you will take 1d4 Necrotic (rust) damage every minute.

Your body has built-in defensive layers, which can be enhanced with armor:

• You gain a +1 bonus to Armor Class.
• You can don only armor with which you have proficiency. To don armor other than a shield, you must incorporate it into your body over the course of 1 hour, during which you remain in contact with the armor. To doff armor, you must spend 1 hour removing it. You can rest while donning or doffing armor in this way.
• While you live, the armor incorporated into your body can't be removed against your will.

When you take a long rest, you must spend at least 4 hours in an inactive, motionless state, rather than sleeping. In this state, you appear inert, but it doesn't render you unconscious, and you can see and hear as normal. You finish a long rest in 4 hours if you spend those hours in this motionless state.
