The Unbreakable

[If you've found yourself here, these are class feats I've created for when the feat update drops. I'm placing them here temporarily for anyone who is nosy and wants to look at them ahead of time.]

Class Name: The Unbreakable

Core Fantasy: The Unbreakable is a Constitution-based Breaker who stands in front and refuses to fall. In Dungeon Break operations, they serve as GGA’s living shields, shaping Enhanced Durability into steady mitigation that keeps Gate runs from collapsing.

Level 1 Features

Gate-Hardened Physique (Level 1)
Your body is conditioned by Break drills and Gate exposure.
Rules:

  • Your hit point maximum increases by 1 for each level you have in this class. When you gain a level in this class, your hit point maximum increases by 1 additional hit point.

  • When you spend one or more Hit Dice during a short rest to regain hit points, you add your Constitution modifier to the total regained one additional time (minimum +1).

Frontline Stance (Level 1)
You naturally brace yourself to take the first hit.
Rules:

  • You gain proficiency in Athletics. If you are already proficient in Athletics, you gain proficiency in one other Strength- or Constitution-based skill of your choice.

  • While you are wearing armor and not incapacitated, you gain a +1 bonus to AC.

  • You have advantage on ability checks and saving throws made to avoid being knocked prone or moved against your will.

Level 3 Feature

E-Rank: Damage Sponge (Level 3)
At E-Rank, you learn to roll with incoming strikes instead of trying to dodge them.
Rules:

  • At the start of each of your turns, if you took bludgeoning, piercing, or slashing damage from an attack since your last turn, you regain a number of hit points equal to your Constitution modifier (minimum 1).

Level 7 Feature

D-Rank: Break Anchor (Level 7)
At D-Rank, your presence pulls enemy focus and keeps them locked on you.
Rules:

  • While you are conscious, any hostile creature within 5 feet of you that can see or hear you has disadvantage on attack rolls against targets other than you.

  • This feature has no effect on a creature that is incapacitated, or on a creature that cannot see or hear you.

Level 10 Feature

C-Rank: Relentless Center (Level 10)
At C-Rank, even heavy control effects struggle to move you off the line.
Rules:

  • You have advantage on saving throws against being stunned or knocked prone.

  • When you finish a long rest, if you have any levels of exhaustion, you reduce your exhaustion level by 2 instead of 1.

Level 13 Feature

B-Rank: Fortress Pulse (Level 13)
At B-Rank, you can lock your stance and push your durability out as a shield for others.
Rules:

  • As an action, you enter a fortress state that lasts for 1 minute. While this state lasts:

    • Your speed is halved and you cannot Dash.

    • You and friendly creatures of your choice within 10 feet of you gain resistance to bludgeoning, piercing and slashing damage from weapon attacks.

  • The fortress state ends early if you are incapacitated.

  • You can use this feature a number of times equal to your proficiency bonus. You regain all expended uses when you finish a long rest.

Level 16 Feature

A-Rank: Catastrophe Survivor (Level 16)
At A-Rank, even lethal blows and long fights cannot finish you easily.
Rules:

  • Attack rolls against you can’t score critical hits. If a creature would score a critical hit against you, the attack instead becomes a normal hit.

  • When you spend Hit Dice during a short rest to regain hit points, you treat each Hit Die rolled for this class as if you had rolled its maximum value.

Level 20 Feature

S-Rank: Unbreakable Wall (Level 20)
At S-Rank, you become a moving bunker that holds the Gatefield together.
Rules:

  • As an action, you enter an unbreakable state that lasts for 1 minute. While this state lasts:

    • At the start of each of your turns, you gain temporary hit points equal to your level. If you already have temporary hit points from this feature, you replace them with the new amount.

    • Friendly creatures of your choice within 15 feet of you have resistance to bludgeoning, piercing, and slashing damage from weapon attacks.

    • The first time you would be reduced to 0 hit points while this state is active, you are instead reduced to 1 hit point, and the unbreakable state immediately ends.

  • The state ends early if you are incapacitated.

  • You can use this feature a number of times equal to your proficiency bonus. You regain all expended uses when you finish a long rest.
