Let's make meta-gems great

My suggestions concern the possibility of effectively using meta-gems for any weapon (not just magical ones).
To do this, I suggest adding additional modifiers to weapons and amulets that will give a + to the level of all skills (not just a specific type), but at half the rate
For example, +1, +2, or +3 for two-handed weapons, +1 or +2 for bows/staves, and +1 for quivers or focus
Currently, the use of meta-gems cannot be effective, since +6 or +7 to melee stones or projectiles give a much greater advantage in combat, and the use of meta-gems does not provide an effect that could match the spirit they embody.
