Refractor

Tools of the Trade

At 3rd level you gain proficiency with glassblower’s tools. If you already have this tool proficiency, you gain proficiency with one other type of artisan's tools of your choice.

Refractor Spells

At 3rd level you always have certain spells prepared after you reach particular levels in this class, as shown in the Refractor Spells table. These spells count as artificer spells for you, but they don't count against the number of artificer spells you prepare.

Refractor Spells

3rd: burning hands, thunderwave

5th: shatter, snilloc's snowball swarm

9th: fireball, lightning bolt

13th: ice storm, vitriolic sphere

17th: destructive wave, cone of cold

Refraction Shield

At 3rd level, your tinkering has led you into making a special type of protection that distorts the immediate space around it. As an action, you can turn a shield you’re wielding into a magical light shield called a Refraction Shield, provided you have glassblower’s tools in hand. You gain the following benefits while wielding this shield:

• If a creature’s attack roll equals your AC, the attack fails to hit, rather than succeeds.

• You can use the refraction shield as a spellcasting focus for your artificer spells.

• Once, before the end of your next long rest, you can use a bonus action to gain temporary hit points equal to twice your artificer level. You can also use an action to turn the shield invisible or visible.

• A shield continues to be a Refraction Shield until you use an action to turn a new shield into a Refraction Shield or until you die.

Energy Refraction

At 5th level, you can dampen the energy from incoming attacks and use it to power your own. You can cast absorb elements without expending a spell slot and without preparing the spell, provided you use glassblower’s tools or your Refraction Shield as the spellcasting focus. You can do so a number of times equal to your Intelligence modifier (minimum of once), and you regain all expended uses when you finish a long rest. In addition, when you have absorbed energy using the spell, you can add the extra damage to one damage roll of an artificer cantrip you cast, or on the first time you hit with a spell attack roll on your next turn.

Prism Focus

At 9th level, you use your shield as a prism to strengthen the power of your spells or widen its effective area. When you cast an artificer spell of 1st-level or higher that has an area effect, that deals damage, and has an instantaneous duration, you can modify the spell in one of two ways. You must use your Refractor Shield as the spellcasting focus.

Magnify. You can focus the energy of the spell at a singular point. Choose a creature inside the spell’s area. The spell only affects that creature, and you add a bonus 1d8 to one of the spell’s damage rolls.

Expand. You can spread the effect of the spell at the cost of weakening its overall power. When you cast the spell, you can increase the spell's effective area by 5 feet for each damage die you subtract from it, to a minimum of one die. You can’t use this ability on a spell cast in a line or in a cone.

Superior Absorption

At 14th level, your Refraction’s Shield’s energy dampening functions improve. You can use your reaction to cast absorb elements when you take force, poison, psychic, radiant, or necrotic damage. Additionally, the extra damage from the spell is now a 1d8, and this damage increases by 1d8 for each spell slot level above 1st.

Smart Protection

At 18th level, your Refraction Shield’s abilities are now even stronger, gaining the following abilities:

• The bonus damage from your Prism Focus’ Magnify is now a 2d8.

• The first time you subtract a damage die to increase a spell’s area using your Prism Focus’ Expand, it increases by 10 feet.

• You can cast circle of power and globe of invulnerability without expending a spell slot and without material components, provided you use glassblower’s tools or your Refractor Shield as the spellcasting focus. Once you cast either spell with this feature, you can't cast that spell with it again until you finish a long rest.
