Grung Poison

Any creature that grapples you or otherwise comes into direct contact with your skin must succeed on a DC 12 + 1/4th of level Constitution saving throw or become poisoned for 1 minute. A poisoned creature no longer in direct contact with you can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

• You can also apply this poison to any piercing, slashing weapons, and arrows as part of an attack with that weapon, though when you hit the poison reacts differently. The target must succeed on a DC 12 + 1/4 of your level Con save   or take 2d6 poison damage.
• • When you make a damage roll that deals poison damage, it ignores resistance to poison.
  • When you make a damage roll that deals poison damage to an entity that is immune, the poison deals resistance damage instead. (DM's Choice) 
  • You gain proficiency with your poison and may add your proficiency bonus to any damage rolls made by it. 
• Your poison now scales with your level starting at level 4 with 2d6, then 8 with 3d6, 12(4d6), 16(5d6), and finally 20 with 6d6.
