Spellweaving

Spellweaving is an arcane tradition fixated on understanding the underlying mechanics of magic. Through meticulous study, these spellcasters learn methods to subtly manipulate the weave in order to alter their spells as they cast them. Known as spell weavers, followers of this tradition often find themselves at the forefront of magical innovation and discovery with many taking posts as professors at institutions of magical learning.

Efficient Casting

At 2nd level, your deep understanding of magic allows you to cast spells more efficiently.

When you cast a spell that has a material component with a listed cost, you can use a component worth half as much. This feature does not apply to spells with a material component that is consumed by the spell.

Additionally, when you cast a spell with a casting time of one action, you can shorten the casting time to one bonus action. Once you shorten a spell's casting time in this way, you can't do so again until you finish a short or long rest.

Elemental Alteration

At 2nd level, you master the first in a series of spell alterations uncovered by your extensive studies.

When you cast a wizard spell using a spell slot and the spell deals acid, cold, fire, lightning, poison, or thunder damage, you can substitute that damage type with one other type from that list (you can change only one damage type per casting of a spell). You replace one energy type for another by altering the spell's formula as you cast it.

Spell Shaper

At 6th level, you gain the ability to reshape the area of effect of your spells.

When you cast a spell with a spell slot that has an area of effect, such as a cone, cube, cylinder, line, or sphere, you can alter its shape to any other shape from that list. The new shape must not exceed the area or volume of the previous shape.

Additionally, you can choose to instead alter the area of effect to protect your allies. You can protect a number of allies equal to your Intelligence modifier when altering a spell's area of effect in such a way.

Adaptive Casting

At 10th level, you have learned to adapt your spells on the fly.

When you cast a spell with a spell slot that requires a saving throw, you can change the saving throw from one ability score to another of your choice (you can only change one saving throw per casting of a spell). If the spell requires a creature to make multiple saving throws, only the first saving throw is changed. Once you change a saving throw in this way, you can't do so again until you finish a short or long rest.

Mastery of the Weave

At 14th level, your knowledge of magic has given you total control of your magic power. You can convert lower level spell slots into higher level ones. The combined level of the converted spell slots must be equal to the spell slot being gained. For example, you can convert four 1st level slots, two 2nd level spell slots, or some other combination into a 4th level spell slot. Additionally, you can convert higher level spell slots into lover level ones. The combined level of the spell slots being gained must be equal to the level of the converted spell slot. For example, you can convert a 6th level spell slot into two 3rd level spell slots, three 2nd level spell slots, or some other combination.
