UO Ninjitsu Skill Guide

ninja

Ninjitsu is a stealth-based combat skill introduced in the Samurai Empire expansion. It allows players to use ninja abilities such as animal forms, mirror images, and special stealth attacks. It is primarily a PvP skill but can also be used in PvM for mobility and survivability.

Overview

Ninjitsu is the specialty skill of the Ninja, unlocking a toolkit of stealthy and shape-shifting techniques. To call on any Ninjitsu ability you must carry a Book of Ninjitsu in your backpack, meet the skill requirement for that technique, and have enough Mana to fuel it. The skill's signature power is Animal Form, which lets you take on the shape of various creatures for different combat and utility bonuses; while running, casting it will snap you straight into your most recently used form.

Training Guide

Train by using Ninjitsu abilities from the Book of Ninjitsu. Animal forms and low-level abilities are the most mana-efficient for skill gain.

Mid-tier forms grant faster regeneration or on-hit poison.
High-tier forms add movement speed, offensive bonuses, and poison immunity, topping out at 100 skill.
