What is a 'ninja'?
the Ninja is a new mob - he is quite rare (10% chance of spawning), and is really tough, is hard to kill, etc.
What will he do?
Once he targets you, he can:
Move really fast.
Be very tough to kill.
Drop TNT on you.
ADDED: TNT WONT DESTROY GROUND.
Teleport near or above you when attacked
Do 2 hearts of damage with every hit (on full diamond armour!)
Drop 10 golden apples on death.
What will he look like?
He will look like a headless man, wearing dyed leather armour.
There is no permissions, and there is no configuration either (yet!), because i thought that i would first get the plugin out there, and see what people think
Better 'random' teleporting away.
Done, ninja now teleports randomly.
Ninja cant be damaged by his own TNT
Even more aggressive attacking, more sound effects, etc.
Ninja day - Ninja invasion!
