The Spell-Loom

An inner lattice of runic threads that lets Spell Weavers design custom spells — choosing Threads, layering Filaments, and shaping raw Arcane energy into something entirely new.

How The Spell-Loom Works

Starting at Level 6, Spell-Weaving subclasses (except Heralds and Disavowed) unlock the Spell-Loom — an inner lattice of runic threads that lets you design new Spells during a Long Rest.

Spell Loom Check

d20 + WAM + Aptitude Dice vs DC (10 + sum of all DC alterations)

Success = add spell to list. Failure = roll on Backlash Table.

Crafting Steps

1

Choose a Thread

Select the primary effect type for your spell.

2

Add Filaments

Layer on spell properties like range, duration, and targeting.

3

Pay ARC Cost

Total = filaments + thread costs.

4

Make Spell Loom Check

Roll to see if your design succeeds.

Uses per Long Rest: Equal to your WAM (Weaving Ability Modifier).

Arcane Filaments

Filaments define the shape, range, duration, and targeting of your loomed spell. Each Filament adds to both the ARC cost and the DC of the Spell Loom Check.
