Blessed Arrows

3rd level Archer from the Vale spell, you can do one of two things: 

• You can use an action to imbue your arrows with radiant energy or imbue your arrows with elemental energy of your choice from the following: cold, fire, lightning, or acid. 
  This temporary enchantment lasts for 1 minute, and will end if the bow is dropped. 
  While infused, the bow will deal an extra 2d6 radiant or elemental damage of the infused type in addition to its base damage. This bonus increases to 2d8 at 5th level, 2d10 at 8th level, and 2d12 at 10th level. 
  This trait cannot be applied to legendary weapons. 

• When this arrow strikes its target, it entangles it with strong venomous tipped brambles. The creature takes an extra 2d6 poison damage, its speed is reduced by 10 feet, and it takes 2d6 slashing damage the first time on each turn it moves 1 foot or more without using a teleporting spell. The creature that can reach it can use its action to remove the brambles with a successful Strength (Athletics) check against your save DC. Otherwise, the brambles will continue for 1 minute or until it is removed. 

  Both the poison damage and slashing damage increase to 4d6 when you reach 8th level in this class. 

You can use this feature a number of times equal to your Intelligence or Wisdom modifier (minimum of 1 time). 
The use of this feature will refresh after a short or long rest.
