Daily Punch 11-27-17 Strength of the Mountain feat for DnD 5e

Reading the latest DnD book, I see racial feats are back.  Let’s make a few.  Here’s one for dwarves.

Strength of the Mountain

You are the mountain.  You do not move unless you say to, and you break any who come at you.

Prerequisite(s): Dwarf

Gain the following benefits:

• Your Strength score increase by 1 to a maximum of 20.
• You have advantage on any save or check to stay standing or to keep your balance.
• You gain advantage on checks and save to escape a grapple
• Foes have disadvantage on any save or check against any melee effect or ability you perform that would knock them prone.
