well since you get skillpoints from combat it seems only fair to make the rewards mainly for combat since it wouldnt be fair to somebody who just wants to dig to go and start fighting monsters just to get better at mineing.
anyway the rewards would enhance the players fighting abilitys with a first level that needs to be purchased to acces the second level abilitys, here is what would be done
rewards for sword
level 1: swordsman, sword does 5% more damage
Level 2: Knight, sword does 10% more damage(NOTE combines with 5% so its 15% increase total)
rewards for armor
Level 1: durable, armors durability is increased (the armor can take more hits)
Level 2: blacksmith crafted, armor durability is increased again in addition to the first level
Rewards for bow and arrow
Level 1: archer, arrow does 5% more damage
Level 2: medieval sniper, arrow does 10% more damage (same as sword 15% total)
Rewards for running
Level 1: jogger, you run a little bit faster
Level 2: marathon runner. run even more fast in addition to level 1 bost
Reward for AXE
level 1, improvise,AXE becomes more effective against mobs (not as effective as sword)
Level 2, battle AXE, axe becomes a little bit more effective in combat(still not as good as sword)
