Before you stands a smallish gnome about
4 feet high.
Typical to his race his features are all miniature appearing almost as if
sculpted into stone in their perfection. Small beady eyes peering
inquistively from beneath sparse eyebrows chiselled on a high forehead. The
lips are thin and pursed into greed beset by a smallish chin. Dishevelled
grimy hair falls down in wild bursts frowning at further scrutiny.
A nervous tension seems to grasp him at all hours, the features constantly
twitching and trembling at unseen shadows.
Looking further you notice that...
Jamfal, a male gnome, is in perfect health.

Jamfal is using:
<worn on finger> (Glowing) (Humming) a ring bearing the seal of Telenius
<worn on finger> an ivory and bloodstone ring
<worn around neck> a sandy-brown desert cloak
<worn around neck> a sandy-brown desert cloak
<worn on body> green robes trimmed with peridot
<worn on head> a crown of leaves
<worn on legs> a pair of colorful baggy pants
<worn on feet> a pair of gray leather boots
<worn on hands> some plated brass gauntlets
<worn on arms> a pair of gray leather armguards
<worn about body> a skin from the snow leopard
<worn about waist> a wide bronze belt
<worn around wrist> a bracer of gray leather
<worn around wrist> a bracer of gray leather

a large saddle bag
a fat purple berry

There is more you have to do to cause it to be 100%.

I don't understand what you mean by "gagging isn't 100% failure."

>I don't understand what you mean by "gagging isn't 100%
>failure."

It won't cause them to fail their spell casting 100% of the time.
