Automaton Features

Constructed Resilience

You have advantage on saving throws against being poisoned, and you have resistance to poison damage.
You don’t need to eat, drink, or breathe. You are immune to disease. You don’t need to sleep, and magic can’t put you to sleep.

Sentry’s Rest

When you take a long rest, you must spend at least six 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.

Integrated Protection

You gain a +1 bonus to Armor Class. To don or doff armor other than a shield takes 1 hour, and you must be proficient with the armor.
While you live, your incorporated armor can’t be removed from your body against your will.

Integrated Tool
Choose one tool you’re proficient with (Lockpicking Set).
This tool is integrated into your body, and you double your proficiency bonus for any ability checks you make with it. You must have your hands free to use this integrated tool.
