Deer are easy. Punch them to death. You'll need ~10 Unarmed, Call Down the Thunder, Knock His Teeth Out, Punch, Charge!, and Opportunity Knocks. Find some safe shallow water and start Calling down the Thunder. Pull one deer away from the group so that they can't heal it.
Get 26 Initiative. Opportunity Knocks, let the deer twitch, Knocks, twitch, Knocks, twitch, Knock, Knock his teeth out.
The deer will now run away. Wait a second and set up a signpost trap. It'll heal itself and engage you in melee but won't attack you anymore. Stay in close quarters with it and close the trap around it so it can't flee.
Charge! to 70 initiative, Opportunity Knocks x4, Punch, wait. Let it expend its heal. (Flex! x5, Knock x1, Knock his Teeth out,) REPEAT THIS TWO-THREE TIMES. It will then be dead.
