As a Mechanoid, your creature type is Construct. You don't need to eat or breathe, and you only need to spend 4 hours in a dormant self-charging state to take a long rest. 

You were constructed by something or someone for a specific purpose and are outfitted with an enhancement to suit.

If you are hit with damage equal to, or over half your max HP, with a single attack, you can choose to roll on the malfunction table below as a reaction. You can use this once per long rest. 

1. Backup_Save: You immediately gain temp hp equal to 1d10 + Con Mod.    
2. Retaliate_Protocol.exe:  You can immediately make a non-spell attack against the creature who hit you if they are in range.
3. Error 404: You can immediately cast invisibility on yourself without expending a spell slot. 
4. Power_Surge: You immediately regain one charge of one of your abilities of your choosing. (Excluding spell slots)

You can briefly connect to the interwebs, accessing and downloading information in order to give yourself advantage on a d20 roll. You can do this amount of times equal to your proficiency bonus per long rest. However, you must make a wisdom saving throw or take 2d6 psychic damage, the saving throw starts at DC 15 and increases by 2 each time you use this feature, and resets to DC 15 after a long rest.
