For Clerics Only
Part of the 3E design balances spell-casters by allowing them to write scrolls at 1st level. This edition also allows for creating wands at an early level, but I don't think we need to go that far. The rules call for the caster to spend Experience Points to write scrolls, but balancing them by giving them an ability that makes them advance slower seems harsh, we'll dispense with this cost as well. The material costs will be used to keep scrolls somewhat in check. Obviously we don't want every caster to have 100 scrolls at hand, but there should be a reasonable number (6 for a medium or larger sized creature, 3 for a small) that can be easily accessed (scroll tubes in pockets or on belts) with the extras tucked away in a pack. As many as 3 spells can be put on a single scroll.
Skill Required: Spellcraft
Cost: 30gp x (Spell Level + 2*Feat Adjustment) x Effective Level* + Material Components** + Masterwork Cost***
Spellcraft Check to Create: DC 15 + Spell Level + Effective Level + 3*Feat Adjustment** - Masterwork Bonus***
Level Check to Cast: DC 2 + Effective Level + 3*Feat Adjustment** .. Required only IF: Reader is lower level OR Does not have applied Feats.
Time Required: 1 Hour per 100gp cost of scroll, minimum of 1 hour. The caster is limited to writing 8 hours per day.
*Effective Level: This can be up to the level of the caster. The scroll-writer can choose to write a scroll at a lower 'effective level'. This makes the scroll less expensive and makes the Spellcraft check easier. The effective level applies to all aspects of the spell; range, area, damage, SR, etc.. The minimum level is the level required to cast the spell (i.e. a Wizard must create a Fireball scroll of at least 5th level), including the feats applied (so an Empowered Fireball scroll, which requires a 5th level slot, has a minimum level of 9).
**Feat Adjustment: Applying a Feat such as Empower or Heighten increases the cost and difficulty of Writing a scroll, as well as the difficulty of Reading the scroll. The final cost is increased for every additional Spell Level used by the Feat. The DC of Writing is increased by 3x the Level Adjustment of the Feat. The Level Check of Reading is increased by 3x Level Adjustment of the Feat. If the Feat does not have a level cost (i.e. Spell Focus) it usually cannot be added to scroll and is only usable by the wizard casting from the scroll if he has the feat. Applying Feats to scrolls is expensive and difficult, so scrolls are rarely found with this power boost. Feats such as Quicken Spell and Power Spell are useless on a scroll.
***Masterwork: For an additional 30gp per spell level
(better inks, quills from more exotic creatures, etc.) you can receive
an additional +2 on your spellcraft check.
Tenidar decides to write a Delayed Blast Fireball spell. He's 19th level, and it's a 7th level spell. To get the most bang-for-the-buck, he goes all out and writes it to full effect. 30gp x 7 x 19 = 3990gp. The Spellcraft Check is DC 15 + 7 + 19 = 41. His Spellcraft Bonus is +28 so he needs to roll a 13 or better for a good scroll. If he wanted to Empower Spell this scroll, the cost would be increased to 5586gp, and the Spellcraft DC would be 45.
A reader of this scroll would not have to make a Level Check if she was 9th level AND had the Feat Empowered Spell.
A reader of this scroll would not have to make a Level Check if she was 18th level AND was trained in all 3 Feats. This scroll would be unusable by most readers, even Rogues with Use Magic Device would have a VERY difficult time.
