Runecaster

Trainees in the magic runes of giants, runecasters have a limited ability to recreate the runes of long lost Ostia, invoking a portion of the power of such runes in their craft. While the power to recreate the full runes of old has not been discovered, weaker powers of the runes are still created in cloistered studies and a number of the stronger giant strongholds throughout the planes.

Tool Proficiency

When you choose this specialization at 3rd level you gain proficiency with calligrapher's supplies. If you already have this proficiency, you gain proficiency with one other type of artisan's tools of your choice.

Runecaster Spells

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

Runecaster Spells

Level	Spells
3rd	Alarm, Illusatory Script
5th	Heat Metal, Knock
9th	Aura of Vitality, Elemental Weapon
13th	Banishment, Stone Shape
17th	Animate Objects, Wall of Stone

Runic Infusions

At 3rd level, you learn an additional two infusions, chosen from the runic infusions below. Whenever you would be able to learn an additional infusion, you can choose one from the following list as well. Unlike most of an artificer's infusions, you cannot infuse the rune as they were crafted in the days of Ostia's glory. Instead, you must immediately transfer the rune to a valid object or point, which counts as an infusion for you.

Your first rune transfer does not count against your total number of infusions. When you reach certain levels in this class, you can create more additional rune transfers in addition to your normal maximum number of infusions: two at 6th level and three at 15th level.

Wrathful Blows

At 5th level, you learn to create the rune of defiance to better repel hostile creatures. When a creature makes an attack against you, you can store the attack's power into the rune of defiance (no action required by you). When you hit the creature with an attack or spell before the end of your next turn, the damage you deal is increased by an amount equal to your Intelligence modifier. The stored power is lost once you have used this feature on an inidividual creature, but you can apply the damage to each creature to have made an attack against you.

Typically, this rune is drawn over your clothing or armor, but some runecasters instead tattoo it onto their bodies.

Runic Defiance

At 9th level, you learn to modify your rune of defiance to absorb attacks of those around you. When an attacker that you can see hits you with an attack, you use your reaction to halve the attack's damage against you.

Rune Shield

By 15th level, your rune of defiance constantly strengthens yourself and your allies. You and each creature of your choice within 10 feet gains a +2 bonus to AC and all saving throws.
