You swallow the pure iron (usually kept in a vial with a solution to keep the iron from air exposure) and focus on its innate power.

While the spell is active, you see faint blue lines (even when blinded or your vision is otherwise hindered) connecting your chest with all metal objects within range. As a Bonus Action, you can push an object connected by those lines, causing you and the object to be pushed apart. The lighter object is propelled unless otherwise hindered. 

Objects can and will deal damage to enemies if impacted. Small objects deal 1d4 bludgeoning damage, with larger objects dealing more. Since you can only push objects away from you, only small objects directly between you and your character can be used as projectiles. You may grab items within your reach to use as such projectiles (as part of your bonus action) with a successful slight of hand check.
