Improviser

Your mind is full of ideas and the only thing stopping you from acting on them is a lack of resources.  No matter, you have figured out how to improvise machines by simply taping some things together.  The limit to what you can make is limited only by your creativity and how many random objects are lying around.  If you can dream it, you can build it.

True Calling

At 3rd level, You gain expertise with a set of tools of your choice.

Improvise

Starting at 3rd level, You may ask to receive a list of every randomly sprawled item in a 20 ft. area.  You decide what you want to do with these items and if you succeed a DC 12 Intelligence Saving Throw, your invention works and replicates the effect of a common magic item that you and your DM agree on.

Clumsy Luck

At 5th level, If you fail your first Intelligence Saving Throw when attempting to Improvise, you can roll again.

Improved Improvisation

Starting at 5th level, you may ask to receive a list of every randomly sprawled item in a 20 ft. area.  You decide what you want to do with these items and if you succeed a DC 12 Intelligence Saving Throw, your invention works and replicates the effect of an uncommon magic item that you and your DM agree on.

Fiery Failure

At 9th Level, If you fail both Intelligence Saving Throws, your mechanism accidentally catches on fire. But since you have a spiritual bond with your mechanism you can decide where it launches when it explodes. This acts as a Fireball spell and takes a spell slot of 2nd-level or higher to throw.

Embrace Failure

At 15th level, You now know how to make your designs fail on purpose. Without expending a spell slot you can now cast Fireball (See Fiery Failure description) as if you were making a mechanism that was designed to explode.

Master Improviser

Starting at 15th level, you may ask to receive a list of every randomly sprawled item in a 20 ft. area.  You decide what you want to do with these items and if you succeed a DC 12 Intelligence Saving Throw, your invention works and replicates the effect of a rare or very rare magic item that you and your DM agree on.
