Greatsword Master (5e Feat)
From D&D Wiki
Prerequisites: Prerequisite: Strength 13 or higher
Those who devote themselves to the disciplines of the Greatsword are fearsome warriors to be faced with caution. Upon obtaining this feat, you gain the following benefits:
- You are trained in breaking spear formations. You can ignore the "reach" property of polearms.
- You can grab the blade of your greatsword setting it up to receive a charge. As a bonus action, choose a creature you can see that is at least 20 feet away from you. If that creatures moves within your greatsword reach on its next turn, you can make a melee attack against it with your greatsword as a reaction.
- When you take the attack action, you can forgo all of your attacks to swing your great sword into a large arch, hitting multiple enemies. Every creature in a 5-foot radius must make a Dexterity saving throw (DC 8 + your proficiency bonus + your Strength modifier). On a failed save, each creature in the area take your weapon damage.
