I hunted a wild boar in Pathfinder with my 1st level STR 14 Cleric using a longspear (1d8+3 2-handed), Readied action vs Charge to attack it at 10', followed by an Attack of Opportunity as it left the threatened square to engage me, by my count would have given me two attacks each at 2d8+6, with the boar taking a -2 AC penalty, before it could attack - likely enough to kill it.
I was pretty disappointed when it ran away instead of charging - I had to cast Entangle and then we whittled it down instead!
