Essa Subclass (chosen at Level 3)

In Onan, all 10 Essa subclasses share the Fighter base class. Before Level 3 you are a standard D&D 5e Fighter — Second Wind, Action Surge, Fighting Style. At Level 3, the Essa system comes online. You choose a subclass that defines your resource, your Rig (if any), your Technique list, and your Rule Break — the thing only you can do.

The Fighter is the most common chassis for Essa practitioners in the Shatterds. Standard military training, imperial or independent, produces Fighters. The Essa system grafts onto that base at Level 3 when a practitioner bonds with a Rig or develops an alternate channel — Momentum, Void, or raw body-expressed Essa. Before that point, a Fighter is a Fighter.

Fighter — Shatterds Sourcebook
Key Mechanic: Essa Subclass (Level 3)
At Level 3 you choose one of ten Essa subclasses. Your choice determines your resource system (vials, Momentum, Void, or Internal Reserve), your Rig type (Gauntlet, Full Rig, AetherBlade, or none), your Technique list, and your Rule Break.

Class Features

Essa Subclass (chosen at Level 3)

Subclass
Essa Knight

Gauntlet Rig. Burn a vial every round, hit harder than anything at the table. Pulse Strike replaces any attack in your Extra Attack chain.

Subclass
Edge Knight

Precision Gauntlet. One target. Efficient Burn makes T1 Glow hit above its tier — at Level 5, 25 gp outputs like a T3 vial.

Subclass
Hexslinger

Gauntlet built into a ranged weapon. Long Barrel means all your Techniques fire at full weapon range. You never need to close distance.

Subclass
Warrant

Tracker Gauntlet. Intel system builds 0–4 stacks on a Marked target, each adding +1 DC and +1d4 force damage per stack.

Subclass
Covenant

AetherBlade — Essa-forged magic steel. The blade generates its own EP per short rest for T1 Techniques. No vial, no Feedback Save on those activations.

Subclass
Ironhand

No Rig. No vials. No Feedback Save. Everything costs Momentum, generated by removing threats. The more you put down, the more dangerous you become.

Subclass
Rawcaster

No Rig. Vials, but Feedback DC is 2 higher than standard. No Burn Buffer. On a natural 1, roll on the Wild Surge table instead of taking normal failure.

Subclass
The Still

No Rig. No Essa. The Void is the absence of Essa — undetectable, unseverable, invisible to the Empire's Suppression Grid. You control. You do not strike.

Subclass
Machinist

Full Forge Rig exosuit. Deploy autonomous constructs that act on their own initiative. You manage the battlefield. Your constructs handle the direct engagement.

Subclass
Oathbound

Full Covenant Rig. A specific, binding Oath generates Resonance — free fuel for Mend and Defense Techniques. Break the Oath and the Rig inverts: everything that healed now damages.
