Circle of Construction

Mechanus is the plane of law and order and the home to constructs. Druids who live in Mechanus for an extended period of time or who train under those druids have shown to lose the ability to turn into animals but gain the ability to harness energy from Mechanus and transform into constructs. While these druids lose the ability to transform into animals they still retain a connection to nature which allows them to continue in life as a normal druid would.

 

Wild Shape

You can no longer turn into animals with wild shape, but you could turn into a construct from of them and gain a resistance to non magical slashing, piercing, and bludgeoning. Wild Shape improves as normal but the CR of the construct you transform into must be equal to or lower than your level divided by 4. The construct you transform into cannot have a swimming/burrowing speed until level 4 and it cannot have a flying speed until level 8.

Circle Feature: Bonus Cantrip

When you choose this circle at 2nd level, you can pick one cantrip from the Artificer class spell list.

Circle Feature: Earthen Shield

Starting at 3nd level, you can use your action during combat to call upon the power in world around you to fortify your defenses briefly. Once per long rest you can use your action during combat to take half damage from any source and give you advantage on any constitution saving throw for the next round. At 7th level the number of rounds after using this ability increases to 2, instead of 1. At 13th level this ability recharges after a short or long rest. At 17th level you can use this ability as a bonus action. At 20th level the number of rounds after using this ability increases to 3, instead of 2.

Circle Feature: Mechanical Influence

Starting at 6th level, when not in a construct form, once per encounter when physically attacking an enemy construct, it must succeed a DC 16 wisdom saving throw or be charmed for 2 rounds. The GM still controls the construct.

Circle Feature: Extra Attack

Beginning at 10th level, you can attack twice, instead of once.

Circle Feature: Miner's Speed

Starting at 10th level, you gain power from the energy of Mechanus and the world around you, causing you to gain the ability to travel in the earth. You gain a burrowing speed of 30ft. At 14th level, the distance of your burrowing increases to 60ft.

Circle Feature: Armour Surge

Starting at 14th level, energy of all types flow through you constantly from your connection to Mechanus, granting you the strength of constructs without becoming one. Gain + 1 to your armour class permanently. Also gain 3 free casts of Mage Armour, Barkskin, or Shield of Faith. Expended uses are regained after a long rest.
