You have attuned your essence to a specific subset of veils, empowering their abilities.
Prerequisites
Ability to weave at least 1 veil from a veil set, veilweaving modifier +3.
Benefit
When you gain this feat, choose a single veil set. Add +1 to the Difficulty Class for all saving throws against any effects from the veil set you select.
In addition, when you weave a veil from your chosen set, it gains a +3 bonus to its hardness for each other veil from that set you currently have woven. For example, if you have woven three veils of the same set, they would each have their hardness increased by 6.
Special
You can gain this feat multiple times. Its effects do not stack. Each time you take the feat, it applies to a new veil set. If a veil you weave belongs to multiple sets you have selected using this feat, the hardness increases stack but the bonus to save DCs does not.
