Because I feel like it, I am making a forum game topic. Here is how it works:

1. Describe what the spell cast by the previous poster does to you. (Silliness is encouraged here.)
2. Cast a spell on the next user. This can be any spell, from any fantasy setting; it can even be one you made up yourself.

Here are some more rules, including how to handle edge cases:
* If a second user casts a spell without responding to the previous user (this can happen if people post at the same time, for example), the next user is affected by all the spells simultaneously, even if that wouldn't make sense.
* If, at any point, no spell has been cast, the effect on the next poster is undefined. Said poster should describe what happens, and should still cast a spell on the next user.
* If the spell prevents you from casting another spell, cast the spell anyway.
* Of course, the forum rules still apply to this thread.

Anyway, I'll start.

*casts Unlock on the next user*

I'm transformed into a powerful ogre mage.

I cast "Disintegrate" on the next user.

Fortunately,I was too fast and stepped aside as the spell rebounded off a mirror and hit the OP.

I am unaffected, as apparently Tauto forgot to cast a spell.

I cast Engorge!

The spell backfired, causing me to disgorge.

I cast Time Start.

I start time.

I cast There Be Light on the next user.

Aaaargh! The Light! It'ssss burning! ... Wait. I'm not a vampire and the light is actually useful for reading. Whew!

I cast Amnesia on the next user.

(Forgot what that spell did.)

I cast Return Undead on the next user.

Wraps the undead in nice packages
and returns them to you.

Casts "Second Sight" on the next user.

I have an army of zombies at my command and send them to devour my enemies.

I cast "Ray of stupidity" at the next user.

EDIT: Looks like It was too slow...
I need a "Haste" spell.

Eye know tipe on the forums about gamies like this. I am definite lee stahpid.

Looks like I cast second sight on the next person. Well, someone else did, because I'm too stupid to cast spells.

Since the previous two posters overlooked toxicTom's spell, at second sight it looks like I can now see thrice as good as before.

I cast Plumbumbarum.

Ooops! I dropped my wand! ... Dammit, it's so heavy. And now I even slipped and fell. But at least I can reach my wand again.

I cast prismatic spray on the next user.
