This is what I was hoping for. I am always looking for feedback.
From Alex: I'm sad that I just can't picture how this system works. The way you wrote it up assumes a prior understanding of the other games' magic systems it seems. Can you add some examples of a day full of spell casting? I'm having trouble with the ebb and flow of PD throughout a day of casting. Does this system end up limiting spell casting or making it less limiting? To cast a spell is the sum of pips on the PD supposed to exceed the target difficulty to cast? I thought this was modeled after Shadowrun but Shadowrun counts "successes" not "pips". Why would a caster ever use less than all his PD to cast a spell if the chance of success is greater with more dice? The way you word the system it sounds like the caster [i]chooses[/i] how many PD to use, but what is the incentive/trade-off for using more/less PD?
From Uriel: Eli, your post doesn't explain how PD are lost on a daily basis.
When a caster uses 2 PD on a spell, and fails, does he lose the PD that day? If he succeeds does he lose?
For example:My 1st level MU (middle magic), casts Magic Missile (requires a 4+). He rolls his single PD and gets a 5! Yaay, it works. Does he lose his PD that day? Or can he cast magic missile later? What happens if he fails to roll a 4+? Does he lose his PD for that day?
My assumption is yes, because he regenerates PD while resting, but I am unclear of what constitutes a loss of PD, with the exception of a critical failure.
Also, would a critical failure ALWAYS happen on a snake eyes, even with 3+ PD are used (i.e. the more PD used, the more likely you'll have a snake eyes...and...by the same token...a 12).
My ResponseThanks for all of the comments and questions. It is clear to me that I need to seriously revise the document to make it more clear.
I also should have noted that one of my primary influences was Advanced Heroquest.
A spell caster has a limited pool of power dice that are expended as they attempt to cast spells.
Each spell has a Target Number that needs to be meet in order to successfully cast it
Regardless if the spell is successful or a failure, the power dice are expended.
Theoretical Example of Game Play
Ruleset: Sword & Wizardry
Magic: Standard Spell System
Setting: High Magic Setting
Windjammer, a 2nd Level Magic-User, has had the unfortunate luck to run into a trio of hungry kobolds.
He is full rested so he has 4 Power Dice plus he has a Solar Wand (2 for level, +1 for High INT, +1 for Wand). He has learned and mastered two spells: Magic Missile and Light.
He manages to win initiative and declares he is casting Magic Missile with 1 PD.
He rolls 1d6 and rolls a 4, Success!! a magic missile strikes one of the kobolds inflicting 4 points of damage killing it.
He has 3 PD remaining
The remaining kobolds charge Windjammer but fail to strike him.
Windjammer back pedals to avoid there attacks. He casts another Magic Missile using 1 PD.
He rolls a 2, Failure! He now only has two PD left and the Kobolds press their attack.
One of the kobolds land a hit, injuring the mage.
Windjammer decides to cast Light using 1 PD in the eyes of one the kobolds to even the odds.
He rolls a 6, Success!!. One of the kobold screams and grabs his face as light pours out of his eyes.
He only has 1 PD but there is only kobold left. He decides to save his PD and engages the kobold in hand-to-hand combat.
Theory of Critical Failure
No Alex you go it right. You summed it up better than I did.
Please let me know if what I posted above makes sense.
