Duskblade

The Duskblades are magical warriors who forgo traditional spellcasting in favor of using magic in it's most raw form. They augment both their offense and defense by using the elements of the world around them. While most mages scoff at the simplistic nature of their abilities, the unrefined power of their elemental magic is feared across the lands and they are sought after as soldiers and mercenaries. A master Duskblade can turn any situation to their advantage.

Elemental Bond

At 3rd level, you can create a magical bond between yourself and one weapon, imbuing the weapon with a spark of primordial energy. This ritual takes an hour.

Once you have bonded a weapon to yourself, you can’t be disarmed of that weapon unless you are incapacitated. You can summon that weapon as a bonus action on your turn, causing it to teleport instantly to your hand.

If you bond with a new weapon, your old bonded weapon is destroyed in the process.
