Weapon Qualities – Greatsword

  • AC Defence (+ AC bonus/number of attacks): If you spend your bonus action this round on this quality you gain a bonus for your armour class for the next indicated number of attacks.
  • Base DC (+number): Some of the effects produced by weapons masters has a saving throw to resist. This saving throw is calculated as 8 plus the ability modifier used in the attack roll. This is sometimes increased as you gain skill with the weapon, gain the Weapon Mastery feat or the fighter archetype.
  • Deflect (number of attacks): If you spend your bonus action this round on this quality, you can attempt to deflect several attacks per round. This can be used to deflect melee or ranged attacks with a base of ability mod for weapon using the attack roll as DC. Failure to deflect an attack still uses the ability. On a successful deflect you weapon takes half the damage you deflected.
  • Heavy: Attacks are at disadvantage on attack rolls with heavy weapons. A heavy weapon’s size and bulk make it too large for a non-proficient creature to use effectively.
  • Heavy (additional effects with proficiency): Small creatures have disadvantage on attack rolls with heavy weapons. A heavy weapon’s size and bulk make it too large for a Small creature to use effectively.
  • Stun: On a Crit, the target must make a Con save vs Base DC. If they fail, they are stunned for one round. No effect if they pass. If this effect is increased for longer than a round, then the target receives a save each round to remove the effect. For every 5 points they fail by, they are stunned for another round.
  • Thrown: If a weapon has the thrown property, you can throw the weapon to make a ranged attack. If the weapon is a melee weapon, you use the same ability modifier for that attack roll and damage roll that you would use for a melee attack with the weapon. For example, if you throw a handaxe, you use your Strength, but if you throw a dagger, you can use either your Strength or your Dexterity, since the dagger has the finesse property.
  • Two-Handed: This weapon requires two hands to use.

Weapon Options – Greatsword

  • Arching Slash: When you attack with this bladed weapon, you may choose to target two creatures within your reach with a single attack. This attack uses the same attack roll for both targets and deals slashing damage equal to half your normal damage to each target.
  • Crushing Blow. As an action, you can make a single attack roll with your two handed weapon against an armoured or naturally armoured creature within 5 feet of you. If the attack hits, the target’s AC is permanently reduced by 1 until its armour is repaired, but cannot be reduced below 10 + the target’s Dexterity modifier. This attack has no effect on creatures with magical armour, unless your weapon is also magical.
  • Disarming Parry: When a creature attacks you with a weapon, you may use your reaction to catch their weapon in yours and disarm them. Make an attack roll with your weapon. If the result of this roll equals or exceeds their attack roll, their attack misses and they must succeed on a Strength saving throw or drop their weapon.
  • Hurling Impact. As an action, you can make a single attack roll with your weapon against a Medium or smaller target. If the attack hits, it does normal weapon damage and the target must make a Strength saving throw (against your base DC). On a failure, the target is pushed up to 5 feet away from you. On a critical hit, this attack does 2d8 extra damage and the weapon breaks.
  • Lock Blades. When a creature attacks you with a weapon, you may use your reaction to attempt to lock blades and parry their attack. Make an attack roll with your bladed weapon. You have advantage on this roll if you are wielding your bladed weapon with two hands. If the result of this roll equals or exceeds their attack roll, their attack misses.
  • Sundering Strike: As an attack, make an attack roll with your weapon against a creature wielding a weapon, including natural weapons. If the attack hits, the weapon is damaged, and all attacks made with this weapon have disadvantage. Another sundering strike destroys the weapon. This attack has no effect on magical weapons unless your martial weapon is also magical.

I have managed to even out most of the damage, but also increased it in this case as it is working better with my magical weapon enhancment changes.
