Snakebone Greatbow - Feat

You gain this feat only when attuning to the Snakebone Greatbow, granting you the following benefits:

• Using a charge allows you to fire a piercing shot that will penetrate enemies in a direct line to a maximum of 15ft behind the initial target, or when hitting an enemy whose AC exceeds your attack roll. All enemies are subjected to the same attack roll as the initial target.
• In exchange for your entire movement speed you may use a ‘heavy attack’, dealing 2d6 piercing damage instead of 1d8 piercing. You may use a charge to make this a piercing shot.

This feat only exists due to the lack of implementation of custom actions for magic items on D&DBeyond.
