Expert Trapper

You've learned the precise art of hiding and deploying traps. When you have time to setup a trap, you can tweak your traps to far exceed their potential. 

• When you deploy caltrops, ball bearings, a hunting trap, or similar items or traps that require a saving throw, you can replace the item's DC with 8 + your proficiency bonus + your Dexterity modifier. Additionally, a creature must make the save even when moving at half speed.
• All traps that do damage (Hunting Traps, Caltrops, etc) add 1 dice for every 5 levels of the character. Traps also move up 1 dice. 
  • Caltrops (bag of 20) dealing 1d4 at level 1, 2d4 at 5th,2d4 at 10th, 3d4 at 15th, 4d4 at 20th
  • Hunting Traps dealing 1d6 piercing at level 1, 2d6 at 5th, 3d6 at 10th, 4d6 at 15th, 5d6 at 20th
• When using Hunting Traps:
  • creatures take 1 damage from a failed escape attempt + 1 per 5 levels. (+1 at 5th, +2 at 10th, +3 at 15th, +4 at 20th)
  • The Strength DC to escape is 8 + your proficiency bonus + your Dexterity modifier.
