Trap Master

The Commando knows that the best fights occur on their terms, and have mastered the ability to manipulate their environment through obstructions and traps to achieve that end. You have mastered the ability to create traps and bombs using the materials available to you. 

Using your arcane abilities, your tools and the materials available to you, you can spend 30 minutes creating one of the following traps without requiring additional resources. Traps weigh 15 pounds. You can make 1 trap per short rest. The maximum number of portable traps you can hold is equal to your intelligence modifier (minimum one). 

Creatures must succeed on a perception check against your Spell save DC to perceive a trap you have set, unless they witnessed you setting it. Disarming a trap you have set requires a successful check against your Spell save DC. 

Portable traps: These are created during a short or long rest. Setting a portable trap requires on action, however, you can take one minute to camouflage the trap while it is being set, and this adds 5 to the perception check required to perceive the trap. Portable traps can be disarmed and moved if not triggered; you gain advantage on checks to disarm your own traps. 

Unless otherwise specified, portable traps deal damage deal 1d8 of the damage type specified, plus your intelligence modifier. 

In-place traps: These are built into the environment around you. You can take an additional 10 minutes to camouflage the trap while it is being set, and this adds 5 to the perception check required to perceive the trap. In-place traps are destroyed when disarmed. 

Unless otherwise specified, in-place traps which deal damage deal 2d8 of the damage type specified, plus your intelligence modifier.
