Subclass Cleric Astral Domain

What Is the Astral Domain?

The Astral Domain is built around control of battlefield positioning. Where other Domains give you fire, death, trickery, or war, the Astral Domain gives you the ability to reshape the battlefield through force, displacement, and planar manipulation.

At Level 3 you gain Create Void — a Channel Divinity that deals force damage and pushes enemies with gravitational force — and Planar Reach, a dedicated action resource for spatial effects. At Level 6, Spatial Exchange lets you swap positions with any character on the battlefield as a Bonus Action.

Level 3 Features

Astral Domain Spells

Your Domain grants an expanding spell list that is always prepared and doesn't count against your limit:

CLERIC LEVEL	SPELLS ADDED
3	Blur, Guiding Bolt, Invisibility, Longstrider, Starry Wisp
5	Blink, Slow
7	Banishment, Dimension Door
9	Dispel Evil and Good, Wall of Stone

9 spells total — a toolkit built around speed, evasion, and spatial control. Blink at Level 5 lets you phase in and out of the Ethereal Plane. Slow at the same level reduces up to six creatures' speed, AC, and actions. Dimension Door at Level 7 lets you teleport yourself and one ally up to 500 feet. Wall of Stone at Level 9 creates a permanent barrier that reshapes the physical environment.

Create Void — Channel Divinity

Your Channel Divinity option at Level 3. As a Bonus Action, you create a gravitational void at a target point within range.

UseCosts: BonusActionPoint:1;ChannelDivinity:1
AreaRadius: 5 meters
SpellRoll: not SavingThrow(Ability.Dexterity, SourceSpellDC())
DamageType: Force

On a failed Dexterity save:

• Deal 1d8 + Cleric Level Force damage
• Apply Force(-4, TargetToEntity, Neutral) — a directional push toward the void's center

On a successful save:

• Deal (1d8 + Cleric Level) / 2 Force damage
• No push effect

Create Void scales with Cleric level — at Level 10, every failed save deals 1d8+10 Force damage plus the knockback effect. The push is most valuable in corridors or near ledges.

The void uses Spiritual Weapon sound and animation assets — the effect is visually dramatic without requiring custom assets.

Planar Reach

A new action resource — PlanarReach — that replenishes on rest. This resource powers the Astral Domain's spatial manipulation features and serves as the mechanical foundation for the Domain's identity.

Planar Reach charges appear on your action resource panel, giving you visible feedback on how many spatial manipulations you have available.

Planar Reach powers the Astral Domain's spatial features. Managing charges — when to use Create Void vs. holding them for Spatial Exchange — is the core resource decision for this subclass.

Level 6 Features

Spatial Exchange

The defining Level 6 feature of the Astral Domain. As a Bonus Action, you swap positions with any character within range — ally or enemy.

Using: TrickstersTransposition (base class)
TargetConditions: Character()
UseCosts: BonusActionPoint:1;ChannelDivinity:1
CastSound: Spell_Cast_Utility_MistyStep_L1to3
SpellFlags: HasVerbalComponent;IsSpell;HasHighGroundRangeExtension;RangeIgnoreVerticalThreshold

Key differences from Trickster's Transposition (the Trickery Domain's version):

• Target: Any Character() — ally or enemy, not just your duplicate
• Range: Extended with RangeIgnoreVerticalThreshold — works across elevation differences
• Flags: Includes HasVerbalComponent and IsSpell — it is a real spell, not a passive ability

Spatial Exchange can swap a downed ally out of danger, pull an enemy out of cover, or move an enemy caster into melee range of a martial ally.

Playstyle Summary

The Astral Domain is a spatial controller that treats the battlefield as a resource to be spent rather than a static environment to fight in.

Your combat identity:

1. Create Void — open combat by pulling clustered enemies toward a central point, dealing force damage and disrupting their positioning
2. Astral Domain spells — Blur for personal defense, Slow for multi-target speed reduction, Blink for tactical evasion
3. Spatial Exchange at Level 6 — use it whenever a position swap would change the fight's dynamics
4. Dimension Door at Level 7 — always prepared; extract yourself and an ally from any situation instantly
5. Wall of Stone at Level 9 — permanently reshape the physical battlefield; create corridors, seal exits, split enemy formations
