When Scout Leader Bossum is saved from a perilous situation he will offer you a life debt in the form of a Cannon Charm. This extremely powerful spell will alter the reality of the world to allow for items in the world to change completely, thus altering the Cannon of the games.
The Cannon will only apply to the realm Scout Leader Bossum is in, but it can be incredibly powerful and when used correctly can be a huge boon for the adventurers.
The way the spell works is the DM makes a saving through. The higher the result the more miniscule the impact of the spell. You spell request must also contain 10 words no more no less.
DC - 16-20 = Miniscule chance in the Cannon, A word is changed, a greeting, a color might be different or the season may be called a different name. Nothing to alter the world as a whole.
DC - 11 - 15 = A reasonable change in the world, could have some implications. Could be the relationship between the villain's and hero's, the abilities of a certain weapon type, a custom or tradition changes that works in the adventurers favor.
DC - 6 - 10 = A major change in the fabric of the game. This is something that may have significant impact. It may allow certain races to exhibit certain traits. Monsters to shrink in size. Weapons to have outsized power in the realm, magical abilities to become free flowing. This can have a significant impact on the level.
DC - 1-5 = World altering canon event. Princes can become paupers, powerful beings can be reduced to nothing, gravity can disapear with the whisper of a word, thoughts can be heard put loud, land can change in front of our eyes. You have the power of a god.
