if i add a jewel with enhanced damage to a 20s pelt

is there any advantage to the damage of the ele druid or is the enhanced dmg wasted because its a helm and not a mele char?

ele druid uses spells, enhanced damage (in contrast to enhanced skill damage) only boosts skills based on weapon attacks

lol im stupid does it help or is it waseted?

? yes or no im sorry im dumb

Only melee skills and ranged skills has to do with wepon damage.
You could devide skills like this:
Spells
Attacks
Passive albilities
Auras

So:
Auras like fana, might, conc scale on ur wepon/gear damage
Melee attakcs, ranged attacks uses damage from wep and gear
Spells like tornado, firestorm, blizzard, fireball etc uses + skills and +% elemental damage.

No
