Freeform Magic

Those who use a casting skill to cast (such as Dominance, Faith, Sympathy, etc) have the option of attempting a spell whose exact effects differ from any known and prepared spell they have available. Here is how it works:

• The caster must be using a casting skill
• The caster must be using /5e/House Rules/Mana.md
• The [/5e/House Rules/Mixed Success.md](Mixed Success) rules must be active
• The desired effect must be in line with the power level of similar known and prepared spells. For example:
  • A wizard who can cast Fireball and Lightning Bolt could attempt to cast a fire spell that does fireball damage in a line.
  • A sorcerer who only has Force-themed spells cannot use this ability to create lightning.
  • A warlock of 5th level, regardless of known spells, cannot use this ability to replicate a 9th-level spell.
• The mana cost of the desired effect must be in line with said effect.
  • For example, a caster seeking to combine elements of Fireball and Magic Missile could make a seeking projectile that inflicts fire damage. If the damage is consistent with Magic Missile at 1 Mana, the desired effect would cost 1 Mana. If the damage is higher--as in Fireball--the mana cost should be 3.
• Casting the spell requires a skill check in order to succeed.
  • DC = 15 + Mana Cost
  • Perfect Success: the spell succeeds as cast.
  • Mixed Success: the spell succeeds, but there are side effects. (Use wild magic tables or something to that effect)
  • Failure: the spell fails, AND there are side effects.
  • Regardless, the Mana and actions are spent.
