“Strike with the force of thunder, and the speed of lightning”  -Führer Jumen

Arc Striders strike with ferocity while navigating the battlefield as if they were a Roc. They harness the raw electrical current that sits in the very air itself, using it to their advantage, striking an opponent before they get a chance to draw their sword. These advanced warriors are the Brotherhood's frontline defense.

Arc Form

As a bonus action on your turn, you may enter your Arc Form. This lasts for 1 minute or until dismissed (no action required). While in this form you gain the following effects:

• Your weapon attacks deal an additional 1d6 lightning damage
• Creatures you have grappled take 1d6 lightning at the start of their turn

On failure, the target is also pulled 15 feet towards you. Creatures that are pulled into the cyclone take an additional 6d10 Lightning damage and are blinded and deafened.
