Weirwood

Weir trees resemble oaks but have leaves that are

brown (with a silver sheen) on their uppers and velvety black

beneath. If undisturbed, weir trees grow into huge, many-branched

forest giants. Weirwood won't ignite in normal (nonmagical)

fire and is resilient and durable. It's favored in the

making of musical instruments because of the unmistakable

warm, clear tone it imparts.

Weirwood can be used as a replacement for oak or holly in any

spell. It grows throughout Faerun but is very rare. Most trees are

now found deep in large forests and actively protected by dryads,
