Yea, that'd be awe. =P
Zeth has also asked me to teach everyone about the wonderful site www.myth-weavers.com
Go there, create an account if you haven't already, then go to Sheets. Click "Create New", name it whatever your character name is, and under Type, select "New World of Darkness". From there, you'll find that it's quite easy to fill it in. Much simpler then writing it all out in PM, trust me. Here, for example, is Angelo:http://www.myth-weavers.com/sheetview.php?sheetid=1108111
Now, Improvised Spells: They're really quite simple. If it's one of your two ruling Arcana (let's use Angelo as an example, so for him, Mind and Space), it's a freebie. If it isn't, you must pay 1 point of Mana. This is ON TOP of any other Mana costs, so for example, if Angelo wanted to cast an improvised Healing Heart spell (a spell with a 1 mana cost), that would require him to spend 2 points of Mana-something he can't do til Gnosis 2.
Once you've paid the Mana, you roll (Arcana)+Gnosis. Let's say Angelo wanted to improv cast "Opening the Lidless Eye" (Mind 2, so free for him). He would roll his Mind of 2 plus his Gnosis of 1, for 3 dice. If you make the roll, hooray, the spell goes off. If not, well, it doesn't happen. Paradox rules apply the same to improv spells.
And really, that's all there is too it. Improvised spells follow all the same rules as Rote spells. Granted, improv spells don't need any kind of motions or chanting (like Rotes do), but for the most part, Rote spells have a lot of advantages over Improvised versions.
