While we are on corrections. Fury lion illusion is not a 'fun' spell, but a core buff which is first recieved at 20. Raises HP, AC, Power, and adds our Maul proc. Unfortunately we gotta run around in it all the time when hunting unless ya got an Eye illusion, which I don't. Believe me, it's not fun for long. Except when noobs run up to me in CL thinking I'm a named lion and try to kill me. heh Otherwise I'd rather see my character, frankly.
Fun spell at 20 for Fury is Faerie Fire. Basically it surrounds a targeted foe with green light/fire. Cool, now I can light up the main target and cause some framerate problems for some people. Oh, and that high level ^^ mob might be [Removed for Content], cause the spell generates agro, which is something Furies definately don't need more of, hehe.
Basically, I've cast it twice and that's it. Most classes got [Removed for Content] on fun spells, except Pal/SK.
