Rune Smith

The runes of the giants grant unique magical power to flow through talismans and enhance the strength of the soldiers. The apex of the forge, Rune Smiths can harness the power of runes, an ancient practice originated with giants, in a new and enhanced way in their talismans, armour, and weapons.

In the land of Tarvelia, Rune Smiths play a key role in the strength of the Ironholde armies. While their strength in numbers is outmatched by the other kingdoms, the technologies granted by Rune Smiths definitely outgun anyone who dares oppose them. 

Battle Ready

When you reach 3rd level, your combat training and your experiments with magic have paid off in two ways: 

• You gain proficiency with martial weapons. 
• When you attack with a magic weapon, you can use your Intelligence modifier, instead of Strength or Dexterity modifier, for the attack and damage rolls. 

Arcane Hammer

When you reach 3rd level, using The Right Tool for the Job class feature, you can create an Arcane Hammer in place of a set of artisan’s tools. Your Arcane Hammer is a magical set of smith’s tools.

Rune Branding

At 3rd level, as an action you can brand runes to weapons to grant them special abilities which ends after 1 minute, or if you brand another rune, or unless stated otherwise. Whenever you create an Arcane Hammer, you can prepare two runes, from among the runes described below, that are shaped on each end of the hammer head. You can brand a rune a number of times equal to your intelligence modifier, you regain all uses after finishing a long rest. 

You learn 3 runes at 3rd level and learn more as you gain levels in this class as shown Runes Known table. Every time you level up in this class, you can replace a rune you know with another one. The Runes Known table also shows your Rune Die which is applied to certain runes and increases as you gain levels in this class.
