Wondrous Item

Rare

In some rare cases, such as when minerals crystallize in an area deeply infused with magic or where planar forces converge, certain crystal formations can act as a prism for the Flow. Such crystals are highly prized among Siverain, since they can be used to enhance or customize the properties of a Weaveblade.

To attune to a weave crystal, you press it into the handle of a melee weapon. The crystal fuses with the weapon and cannot be removed until your attunement to it ends. If that weapon is a Weaveblade, its blade color may change depending on the crystal used. The color of a blade affected by a weave crystal can be determined by consulting the Weave Crystal Color table.

When you fuse a weave crystal with a weapon, the weapon becomes magical if it is not already.

Weave crystals that form within a vein of adamantium ore can pull traces of the wondrous metal into themselves, making the crystal heavier than usual. An arcane blade filtered through such crystals takes on a metallic, reflective quality. While attuned to this weave crystal, Siverain weapons that you create have the heavy and two-handed properties. When you hit a structure or object with an attack using a Siverain weapon with the heavy property, the attack deals an additional 2d6 force damage and scores a critical hit on a roll of 19 or 20.
