Warbound

You feel the energy of the arcane coursing through your body. It calls you to war.  While most magic users spend their days in libraries or standing at the back protected from the masses. You stand in the front line greeting them with a smile. 

Arcane Blade

At 1st level, you gain the following benefits:

You gain proficiency in light and medium armor

You can use your bonus action to summon a weapon of pure arcane energy to your hand.  You are consider proficient in this weapon and it may take any form, but is not consider that weapon type.  This weapon deals 2d4+Spell modifier force damage on a successful melee spell attack. Additionally you may spend 2 sorcery points to cause the weapon to explode after a successful hit against a creature you are not friendly to, dealing an additional 2d4 force damage to all creatures within 5 feet.  You and the creature hit by the melee spell attack are not subject to this damage. The weapon is destroyed in the process and you can not re-summon until you next long rest. You may dismiss and re-summon the blade using your bonus action so long as it wasn't destroyed within your last long rest. The damage increased by 1d4 at level 5, 11, and 17.

Arcane Aegis

You focus your efforts into a defensive shield that shimmers around you.  As an action to you summon your aegis to protect you. When you do you are granted temp HP equal to half your level and you can add you charisma modifier to you AC.  This effect only lasts 1 minute and you can’t used it again until a long rest.

At lvl 17, your aegis grants you resistance to piercing, bludgeoning, slashing and force damage. 

Negotiation

The magic around you whispers in your ears.  You become proficient in Persuasion if you aren't already.  Whenever a creature speaks to in a language you don’t know, you slowly begin to understand what it is saying.  If you spend 1 minute listen to a creature that speaks a language you don’t understand, you learn the language for the remainder of the conversation. After 10 minutes of not hearing or speaking the language you forget it.

Thrill of Victory

At 14th level, when you hit a creature in combat with a critical hit using your arcane blade or kill a creature in combat with an arcane blade you regain a sorcery point.  This can only happen once per round and you can't recover more sorcery points than your current maximum.

Arcane Warlord

Beginning at 18th level, you control the flow of arcane energy all around you. You can use the following abilities each once per short rest. 

As an action to you channel your arcane energy into your body.  Creature within 10 feet of you that you choose must make a constitution saving throw versus your spell DC or be paralyzed.  This ability works through total cover

As a bonus action a creature that is friendly to you and within 10 feet can gain resistance to force damage.  You can extend this resistance to additional friendly creatures up to 3 creatures by spending 4 sorcery points. 

As a reaction you can disrupt the spell casting ability of any creature within 20 feet of you regardless of whether you are aware of them.  The creature must first make a constitution saving throw vs your spell DC to be able to overcome the arcane energy flowing out of you.  On a fail, the creature takes 3d10 force damage and the spell is lost.  On a success the creature can cast the spell as normal and takes no damage.
