Surge Knight

Your use of action surge is now able to be used for other abilities known as "Surges". 

Surges

At third level you now are capable of using surges. You have three (3) surges you can use for various abilities. You gain more surges at 10th level (5) and 17th level (7). You regain all surges after a short or long rest.

Defensive Surge

At third level, you may spend a surge as a bonus action or reaction to grant yourself and friendly creatures within 15ft of you one of these abilities for one minute. If a friendly creature was within 15ft of your character and then becomes more than 15ft away from you, they no longer benefit from Defensive Surge.

• Roll a d10, add that value to your AC.
• Gain resistance to bludgeoning, piercing, and slashing damage from a non-magical source.
• Reroll a saving through once during this round per person. You must use the new value rolled.

Retaliatory Surge

At seventh level, as a reaction, if you or a friendly creature within 10ft of you is hit by an attack, you may spend a surge to allow yourself or said friendly creature to take half the damage and have the attacker take the other half. Then, on you or the friendly creature's next turn, gain advantage on attack rolls against the enemy creature that attacked the target of this ability.

Smiting Surge

At tenth level when you successfully hit a creature, you may spend one or more surges to add 3d8 to the damage roll for each surge used. This damage is of the same type as the weapon being used but is considered magical for the purpose of overcoming resistances.

Critical Surge

At fifteenth level, when you roll a critical hit on an attack roll, you may use a surge to roll four times the number of hit dice instead of twice.

Accuracy Surge

On an attack, you may spend one surge charge to use accuracy surge before you roll an attack roll. If you do, you crit when you roll an 18, 19, or 20. Additionally, if you crit with this attack, you gain the benefits of Critical Surge or one charge of Smiting Surge for free.
