You approach to 10 yards distance. You can fire 3 shots at pointblank range at a huge target. (There are so many orcs that together they make up a huge target). Choose your weapon. Make a L1-SR on Dex. Note that any skill levels may be taken into account when making the SR.

If you make the hit, subtract damage from the orcs con.

To return:
Make two L1-SR on speed to return safely.
If you fail, this person is dead. The others enter melee.
