Hello, I have a question about the number of spell slots for a wizard with the following feats :
School of Unified Magical Theory :
instead of using Drain Bonded Item only once per day, you can use it once per day for each rank of spell you can cast, recalling a spell of that rank each time.
0/ 1st rank to 10 rank ?
Bond conservation (1 action) (8) :
You gain an extra use of Drain Bonded Item. You can use it to cast a spell 2 or more ranks lower than the previous spell, and must use it before the end of your next turn or you lose it.
1/ is it an extra use for a single spell or an extra use for each rank of spell ?
superior bond :
You can use Drain Bonded Item one additional time per day, but only to cast a spell 2 or more ranks lower than your highest-rank wizard spell slot.
2/ Same question that in 1/.
Spell combination :
One slot of each rank of spell you can cast, except 2nd rank and 1st rank, becomes a spell combination slot (this doesn’t apply to cantrips). When you prepare your spells, you can fill a combination slot with a combination of two spells. Each spell in the combination must be 2 or more spell ranks below the slot’s rank, and both must target only one creature or object or have the option to target only one creature or object. Each spell in the combination must also have the same means of determining whether it has an effect—both spells must require a ranged spell attack, require the same type of saving throw, or automatically affect the target.
3/For example, a slot from 8th level rank to prepare 2 spells of 6th rank or lower ?
a spell slot from 4th rank to 10 th rank ?spell mastery :
Select any four spells of 9th rank or lower that are in your spellbook; each spell you select must be of a different rank. These spells are automatically prepared when you make your daily preparations, and you gain an extra spell slot for each spell. You can select a different combination of spells by spending 1 week of downtime studying your spellbook and retraining your mastered spells.
+ 4 spell slots from 9th rank or lower
Spell battery from a master ability for a familiar :
+ 1 slot from 6th or 7th rank maximum ?
Thanks for your future answer.
0/ No, only 1st to 9th. Like all other features that grant a 10th rank spell, Archwizard's Spellcraft specifies that effects that grant additional slots or let you cast spells without slots do not work on it. Arcane Bond and Unified Magical Theory would need to outright specify that they can break this rule, which they does not.
1/ The feat says an extra use of Drain Bonded Item. No specification that it works differently with UMT in either the feat or the School, which would be needed to make it one per slot.
2/ Same answer and in fact the wording is more strict by saying one use.
3/ Correct, mostly, I think. This one doesn't give you any new spell slots, it alters their function by letting you prepare two simultaneous spells in a slot you already had. Also, the lower end is 3rd rank, not 4th, and it stretches to... Well, at least 9th, I'm actually not super sure how 10th rank spells' usual restrictions would apply to this, but I think it's kosher since you're technically not getting new slots.
Spell Battery gives you 7th rank max, and Spell Mastery is indeed there too.
