Stone adding explained

When adding stones to a weapon stick with one element, with monsters being somewhat resistant to elements this tends to hit harder on more mobs and a ton more in PvP.

If your spells are wind based go wind stones this will increase the Wind % dmg from your spell dmg slightly for maximized dmg output.

Elemental stones add in a flat damage to your total attack.

Its recommanded that you slot in the same elements cause each one will give you a +1 bonus.

It works like this:

Each
LvL 1 stone give you +3
LvL 2 stone give you +4
LvL 3 stone give you +5

Say you have a 4 slot weapon, slotting 4 lvl 1 stone will give you:

3+3+1+3+1+3+1=15 dmg

LvL 2 stone

4+4+1+4+1+4+1=19 dmg
