I've been trying to train with slings, but it is about 100x slower than a melee skill, I had to shoot 600 shot to gain 1.8 points in sling with a 4.2 food multiplier 30-31.8 (my character started at 30) THEN i spent 2 hours gaining more shot ammo to gain another .6 points? this CANNOT be true gameplay. I have not tested archery but please please please do not make this the way the game is supposed to be grinded!
This will take me some 6 months of constant training to get an appropriate level in archery, hell i might as well go join an archery club near my house, I'll learn faster!
