This is general theory crafting surrounding the Shadow Illusion (Su) feature of the Shadow Craft Mage in the hopes of maximizing every potential spellcasting slot a character has.
Earth Spell requires a spell to be used in a higher-level slot in order to "active" and give it's +1 spell level and +x Spell caster boost. Using Sanctum Spell we are trying to lower the effective spell level of the original spell so that easy meta magic and heighten spell can be applied on the spell in its original spell slot and receive the bonus from earth spell.
I would appreciate help in understanding if what I'm trying to do is legal and if I'm calculating this correctly.
The Metamagic Combo:
- Heighten Spell - To Increase the effective spell level of a spell by +1 or more, increasing slot requirement.
- Sanctum Spell - To lower the effective level of the spell by -1 without a slot modifier.
- Earth Spell - To Increase effective caster level of the spell by +2, and retain out +1 to effective spell level.
The three above feats represent the core of the skill interaction I'm trying to understand. We use Sanctum Spell to preserve our Earth Spell interaction on our lowest level spell slots.
- And then we layer on either: Practical Metamagic -or- Easy Metamagic - so we can get an additional +1 to final effective spell level without increasing the spell slot used.
If I stack one instance of all four meta magics onto the 1st level spell Silent Image is it:
A 0th level spell counted as a 2nd level spell prepared in a 1st level slot with a +1 caster level boost?
- Or -
A 1st level spell prepared in a 2nd level slot with an effective Casting level of a 2nd level spell with a +1 caster level boost?
What does this look like as I start stacking on more and more levels of Heighten Spell onto Silent Image?
I apologize if this all seems messy - but I'm at the point I know I'm confusing myself trying to puzzle fit this together.
