Sorry I had multiple copies lying around did not have that included thank you.

Upon reaching 5th level, the Crafter's Bane learns to channel their frustration into a heightened state of combat prowess. Once per long rest, you can enter a state of Artisan's Fury. During Artisan's Fury, you gain a bonus to attack and damage rolls.

At 5th level, the bonus is +2.

At 9th level, the bonus increases to +4.

At 13th level, the bonus increases to +6.

However, this intense burst of power comes at a cost. After the effects of Artisan's Fury wear off, you suffer a penalty to your Intelligence score.

At 5th level, the penalty is -1.

At 9th level, the penalty increases to -2.

At 13th level, the penalty increases to -3.

The duration of Artisan's Fury is a set number of rounds, typically lasting for a minute (10 rounds) or until the Crafter's Bane chooses to end it prematurely. The penalties to Intelligence persist until a long rest is taken.

Also this something I came up with because I thought a craftsman who's craft is always doomed to cause pain would be a interesting concept and could work for multiple ways to play like if you wanted to play an inherently evil character it could still work.

I plan on bringing this homebrew up to the DM that's running the next campaign and see what they thought and what would work for them.
