Suzy: ' Didn't know we were hard focusing on ranged enemies. Ummmm.... *Taps my foot as I think.* If there are pieces of organic matter like wood nearby I could break it into splinters and chunks to launch towards them? I really can't think of anything I would have directly on hand that I could use.
Suzy: *Is quiet while tapping my foot for a long while.* Could my sweat, hair, or, if I'm hurt, blood, be used?
Sweat is mostly water and salt. It's not very effective. Hair could work, but is too flimsy and soft to do damage. Blood is the correct answer. You can easily solidify and reinforce it to use as a weapon or bullet.
