Bountiful Luck

Prerequisite: Halfling      No limit on race 

Your people have extraordinary luck, which you have learned to mystically lend to your companions whenever you see them falter. You're not sure how you do it, you just wish it, and it happens. Surely a sign of fortune's favor!

• When an ally you can see within 30 feet of you rolls a 1 on the d20 for an attack roll, an ability check, or a saving throw, you can use your reaction to let the ally reroll the die. The ally must use the new roll. Only works on attack rolls and saving throws, use your reaction for a reroll.
  

     When you use this ability, you can't use your Lucky racial trait before the end of your next turn   Using your reaction removes the Halfling luck bonus temporarily.


Piercer Feat

You have achieved a penetrating precision in combat, granting you the following benefits:

• Increase your Strength or Dexterity by 1, to a maximum of 20.           Implemented
  

• Once per turn, when you hit a creature with an attack that deals piercing damage, you can re-roll one of the attack’s damage dice, and you must use the new roll.
• As I could not get this to proc with a reaction the reroll will be at advantage (small mathematical bonus). I have only tested with melee and ranged weapons. If you use slings it might proc, no idea why.
  

• When you score a critical hit that deals piercing damage to a creature, you can roll one additional damage die when determining the extra piercing damage the target takes.
• On testing with weapon attacks this worked.
• Throwing: i could not get a reroll to work with thrown weapons, and unable to check if the thrown item was doing piercing damage, so on a hit it will do an extra 2 piercing damage if throwing a weapon with the thrown property that does piercing damage, double on a critical hit.
  

Polearm Master - this is a fix for the bonus action attack. I tested and it now adds weapon enchantment, weapon functor damage, and strength modifier in damage.
