Boobytrap & Weapons Tinkerer

You’ve developed the skills necessary to develop deadly booby traps, and mod existing weapons. You gain the following benefits: 

• You are able to use your create traps to be used against creatures - ex add string to grenades to create deadly tripwire grenades, or add ball bearings to a gernade (max 40) to deal extra damage (multiple of 10s x d4 piercing damage)
• You can create compound weapons from existing weapons to give them specific properties - ex Shortsword and flame source to give the shortsword the ability to deal burning damage. 
• You are also able to use adhesives or bindings to attach explosives to weapons to increase the range by up to 40ft. However, you lose the weapon in the process.
