Request random effect wand

[Frillinde]

I had an idea about a wand/rod that would cast a random effect at its target each time it shoots.....melee,poison,energy,ice,etc.
How would I set this up? I was gonna give a really wide damage range (1-70) so you never know what the attack will be ( or be useful) and it can barely hurt something or do some real damge.
Hope someone can help.

Nobody wants to try this 1?Ive made new wands and rods but I have no clue how to do the random effect part.

I was also thinking about a failure effect(big cloud) and having it skip the attack as 1 of the random effects.
Would the weapons xml for this have script for "event type" or would it still be function?
