Hi Sona mains.

I'm new to sona, and my build is swiftness, the support healing tear item, the chalice green item and moonstone, iirc but i see a lot of people build Fimbelwinter.

The thing is, fimbelwinter slow>shield only works when the champ is melee, so Dona shouldnt benefit from it except when she ult, is it that good item anyway?

Also, is sona healing not really good? I feel like i dont heal much even lategame, having in consideration that sona W doesnt lower cooldown with levels.

Edit: mb, what i currently build is first back tear, then i build the chalize one (idk the name), then i go rush swiftness and then tear item. After the tear item i go with moonstone.

I know that Sona's W ability, Power Chord, reduces all enemy damage in general, but if it also reduced true damage, would that be good or would it be too powerful?
