Weirwood

Weir trees are now rare and highly prized. Most that survive are deep in the larger forests of Faerfin and actively protected by dryads, treants, druids, and rangers. If undisturbed, weir trees grow into huge, many-branched forest giants. They resemble oaks in appearance, only with leaves that are brown with a silver sheen on the upper surfaces and velvety black on the undersides. Weir wood does not burn in normal (nonmagical) fire and is resilient and durable. It is favored for the making of lutes, harps, birdpipes, and longhorns because of the unmistakable warm, clear sound it gives to such instruments. Any magically generated radiance (such as dancing lights) that is brought into contact with cut or living weirwood lingers around the wood for 1d4+1 rounds after its source expires or is removed — unless the weirwood has any active enchantment upon itself, which negates this property. Weirwood serves as a replacement component for all spells that normally use oak or holly (bark, leaves, berries, or the wood) and can replace any one consumed component that does not need to be specially constructed in spells that create magical radi¬ance or that provide some protection against, or resistance to, normal or magical fire. If used as an extra material component in spells that create or mend objects (such as mending, wondrous web, awakening, enchant an item, holy vesting, or ritual of transfer¬ence), it confers a bonus of +1 to all saving throws and ability checks involved in the spellcasting.
