Master Craftsman

Starting at 1st level, your bond with The Architect grants you an innate ability akin to the fabricate spell. As an action, you can rapidly construct simple items or parts of larger complex structures, similar to how fabricate works, but on a smaller scale. Complex creations take longer and may require additional actions or rest periods, depending on their complexity and size. This ability can be used a number of times equal to your Charisma modifier (minimum of once), and you regain all expended uses when you finish a long rest.

Architect's Design (6th Level Ability)

Starting at 6th level, your deep understanding of creation allows you to weave magic into the very structures around you, offering both protection and empowerment to your allies within a 30-foot radius. This radius manifests your architect's mind in the following ways:

• Bulwark of Design

  As a reaction when an ally within your radius is targeted by an attack, you can conjure a spectral rampart or shield-wall. This ethereal structure, reflecting the grand designs of ancient fortifications, grants the ally a bonus to their AC equal to your Charisma modifier (minimum of +1). The sudden appearance of these architecturally sound defenses might be enough to turn a hit into a miss.

• Strike of the Design

  As a reaction when an ally within your radius makes an attack, you can momentarily reinforce their position or weapon with an architecturally inspired construct. Be it a temporary stone footing for better leverage or a brief, spectral bracing on their weapon, the ally gains a bonus to their damage roll equal to your Charisma Modifier.

• Eye of Design

  As a reaction when an ally within your radius makes an attack, you can grant them an mental insight to their target granting them advantage on their next attack roll. This decision must be made before the roll has been made.

You can use the Architect's Design ability a number of times equal to your Charisma modifier (minimum 1), regaining all expended uses after a long rest.

Transformative Aura (10th Level Ability)

At 10th level, the ability to transform the properties of materials within your aura, bending them to your will. As a bonus action, you can activate a 30-foot radius aura centered on yourself. This aura lasts for 1 minute and grants you the following abilities:

• Architect's Insight

  While your aura is active you can perceive hidden objects and creatures within your aura even if they are considered behind total cover. While a creature is within your aura they gain no benefit from your attacks and spell saving throws while they are behind total cover.

• Material Adaptation

  You can use an Action to change the properties of materials within your aura. For example, you can make stone temporarily as pliable as clay for easy shaping, or wood as resilient as iron for defensive purposes. This adaptation can be used to aid in fortification, creating traps, or facilitating movement.

• Environmental Reshaping

  As a bonus action, while the aura is active, you can reshape the terrain within the aura, creating temporary structures or obstacles, altering the height of the terrain, or creating/removing areas of difficult terrain, this change removes any difficult terrain penalties for you and your allies within the aura. These changes last for the duration of the aura.

This ability can be used amount of times equal to your proficiency bonus. You regain all uses once you finish a long rest.

Architect's Mastery (14th Level Ability)

At 14th level, your profound connection with The Architect and your understanding of creation and transformation culminate in a formidable ability: Architect's Mastery. This ability reflects your ability to manipulate and control materials and structures on a grand scale.

• Grand Fabrication

  As an action, you can exert your will to fabricate a large structure or significantly alter the environment within a 120-foot cube. This can include creating buildings, bridges, fortifications, or other architectural constructs, as well as reshaping existing structures or terrain. The creation or transformation is permanent but must be composed of materials present in the environment.

• Elemental Transmutation

  Twice per long rest, you can transmute elemental materials (stone, metal, wood) within a 60-foot radius around you. You can turn walls into transparent crystal for improved visibility, change metal compositions, or harden wood into iron-like strength. These transmutations last for 1 hour.

Architect's Mastery can be used once per long rest.
