Swordmage

Ancient swordmages of the past combined swords with sorcery. You may be a descendant of one of these powerful masters. Or you may just be naturally gifted with the arcane arts and have a knack for weapons.
     Your magic springs from a mystical link between the magic in your soul and the innate aptitude for weaponry. You might trace a distant ancestor to an ancient sorcerer of the past who combined the might of their sword with sorcery, or you may just be naturally gifted with the arcane and have a knack for weapons. Whatever your past, magic is inherent in your blood along with an affinity fore blades. This link grants you extraordinary resilience and your natural affinity for combat make a steel blade feel like a natural extension of your body. Sorcerers with this origin have a knack for wielding both shields and weapons. In combat your place is amid the fray. You rely on your arcane prowess to shield you from harm and your blade magic to overwhelm your foes.

Blade Magic

If a spell grants you a melee attack with a weapon as part of casting the spell, it counts as a Blade Magic spell for you.

At 1st level, you gain proficiency with shields, simple weapons, and martial weapons.

You also add two Blade Magic cantrips to your known spells list.
(examples would be booming blade and green-flame blade.)

Swordbond

By spending 1 hour of meditation with a chosen melee weapon, you forge a special bond with the weapon. If you forge a bond with a different blade, the old bond dissipates.
     If your bonded weapon is broken or damaged, you can spend 1 hour of meditation to repair or recreate the weapon from a fragment. All other fragments lose any unique or magical properties they may have once had. The bonded weapon can only be repaired up to the condition it was in when you bonded to it.
     As a bonus action, you can call your bonded weapon to your hand from up to 60 feet away.
     You can also use your bonded weapon as a spell focus for your sorcerer spells.

Swordmage Warding

At 1st level, your connection to blade magic gives you extra fortitude. Your hit point maximum increases by 1, and it increases by 1 again whenever you gain a level in this class.

You also can gain a base AC of 13 + your Constitution modifier if you aren’t wearing armor.

Warding Style: You gain an additional 2 AC if you are wielding only a single one handed melee weapon. This benefit counts as using a shield and will not stack with things like bracers of defense. (You can benefit from only one shield at a time.)

The following are options to choose based upon whether or not you are going to use a shield. If you are not benefiting from a shield, choose Warding Style. If you are benefiting from a shield (like using a shield, +1), choose No Style.

Swordmage Aegis

Starting at 6th level, your command of blade magic grows stronger, allowing you to harness it for your allies’ protection.

Shielding Aegis: As a bonus action, you can grant an aegis to one allied creature you can see within 60 feet of you. The aegis is a dim, gray aura of arcane energy that protects the target. Any bludgeoning, piercing, or slashing damage the target takes is reduced by an amount equal to your proficiency bonus. This effect lasts for 1 minute or until you use it again. The number of allies protected by this ability increases to 2 at 11th level and 3 at 17th level.

Assaulting Aegis: As a reaction when a creature you can see within 60 feet of you hits a target protected by your Shielding Aegis with a melee attack, you can use your reaction to teleport to an unoccupied space you can see within 5 feet of the attacker. You can then make one melee weapon attack against the attacker. If that attack hits, it deals an extra 1d10 force damage. This extra damage increases to 2d10 at 11th level and 3d10 at 17th level.

Swordmage Edge

Starting at 14th level, your mastery of blade magic allows you to add extra arcane force to your spells. When you cast a spell that deals damage, choose one creature damaged by that spell on the round you cast it. That creature takes extra force damage equal to half your sorcerer level. This feature can be used only once per casting of a spell.

Grand Swordmage

At 18th level, you have mastered using Blade Magic and can manipulate their magic with ease. You can apply an additional metamagic to Blade Magic spells and the first metamagic applied to the spell cost no sorcery points.
