Ninja
What do you think about this Character Class in the Dungeon & Dragons or (AD&D) system of role-playing? Consider the following:
1. Fighting ability (attack skills, use of weapons)
2. Unique skills (thievery, bless, talk to animals, etc.)
3. Magical skills (ability to use and acquire magic)
4. Tendency to progress (easy to go up in levels)
5. Limitations (cannot carry or use certain objects)
When reading about the Advanced Dungeons and Dragons character Ninja, it appears that the ninja is supposed to have another profession like an Alchemist or something. Its interesting that the character is generally not supposed to "act" like a ninja in that a ninja would not display his profession outwardly since he has a secret profession.

Never did get into the oriental version of D&D characters. I think the ninja is just an over glorified thief.
