Usage held in 1 hand

Bulk L

This thin, wand-like implement is carved from bone and scrimshawed with depictions of battle. While holding the needle of undeath, mindless undead creatures see you as one of their own and are indifferent to you until you take hostile actions against them, and you have a +2 item bonus to Deception and Diplomacy checks against intelligent undead. This does not affect a summoned undead's attitude.

Activate—Speak with Undead

Frequency once per hour

Effect You can use Diplomacy to Make an Impression on mindless undead or make simple requests of them with a +2 item bonus. You cannot make this request of someone else's summoned undead.
