Homebrew feat: Brutish Fighting, designed for Strength based characters

###Brutish Fighting

[Prerequisites: 15 Strength]

Through your sheer muscle power, you've survived countless perils, you gain the following benefits:

• Weapon attacks made using Strength deal an extra 2 damage
• On your turn, when you hit a creature up to 1 size larger than you with a melee weapon attack using Strength, you may expend a bonus action to also push them back 5ft
• When you make a Dexterity save against an effect that targets an area, such as a Fireball spell or a Blue Dragon's breath, you can choose to use a +3 bonus in place of your normal Dexterity bonus, provided you're wearing heavy armor or a shield. This ability doesn't work against effects that target only you, however, such as a Disintegrate spell
