A Thrown Weapon is defined as any coreless (i.e. consisting only of latex and foam, with no hard core) weapon that is 12 or fewer inches long.
You must have either of the Armsmaster or Archer Abilities to use a Thrown Weapon.
You can throw a thrown weapon at a target; if you hit, you deal 1 damage to them.
Please note that thrown weapons by their design tend to have a fairly light impact, and that players wearing Medium or Heavy Armor may not even notice if you hit them on a piece of armor when they aren’t looking. Try to get their attention before throwing something at them so that they are more likely to realize they’ve been hit. It’s your responsibility to avoid this issue, not your target’s; do not get upset at someone for not noticing that they’ve been hit by something you threw at them.
