Playtested the mod with Stormworld.
Had some fun, with web throwing units of Drota, and slinging them.
However the overall feel was they don't scale.
Much like the original throwing knifes, they do minimal damage to begin with and become obsolete later on.
I think, that cooldown is unnecessary for sling at least (though, that could make them overused by bandits if put on throwing knifes).
You could also add bandit units equipped with those to see them ingame used by monsters.
so first, they could receive +1 damage per level
The throwing knives could be boosted either by 5% crit chance or by additional attack
sling with 5% stun chance
and axes with aditional damage like 6 to begin with.
