Mace & Morningstar Master

Prerequisite: Proficiency with the mace or morningstar. 

You have learned how to use any mace or morningstar with more effectiveness than most. This feat gives you the following benefits while wielding a mace or morningstar:

• In your hands a mace does 1d8 bludgeoning damage. Also the morningstar gains the versatile trait, doing 1d10 damage bludgeoning when wielded with two hands . 
• Mage Beater: You can either silence a creature or strike their hand momentarily disabling their ability to cast spells with somatic components. You can attempt this as many times equal to either your STR mod or your WIS mod (whichever is higher) per long rest. On a successful hit the creature makes a STR save vs. your DC (STR mod + prof bonus + 8), if they fail the creature will lose either the ability to speak until the beginning of your next turn or lose the ability to cast spells with somatic components until the beginning of your next turn. 
• If a creature is a construct, wearing medium or heavy armor, or has plate-like natural armor (such as an Umber Hulk) you can add 1d4 to any attack roll made with a mace or a morningstar.
