To support Kallizk's comment, assuming that DiabloWiki is correct:
Thorns damage is increased by your primary attribute, 1% per point, as any other damage.
TIL, thanks for the confirmation!

I was just using Invoker's as an example, to illustrate that you need more than what Necro currently have to make Thorns viable.
So would LoN Petthorn be viable? Possibly, but with (so far) no runes for any skills that support Thorns (like used in LoN Pony), I still think the damage would be lacking.
I do agree that thorns most likely won't be viable for some of the same reasons you list. Specifically because there's no thorns dmg modifier on offensive abilities. Would be cool if on command skeleton/skeletal mage, there was one...
@Kal: Really is this true?! Any one test and confirm or any blue posts about that? I thought it was strength specifically.
@Talyn: there are more viable and better thorns builds than Invokers. The damage boost form main stat is far superior and account for an order of magnitude more dmg output than the dmg buff from Invokers does. E.g LoN Pony bomber or frenzy thorns barb with Hack
Don't forget the thorns gem... will probably use that with pet builds that grant the pets your thorns damage.
Eh, even with the Thorns gem, the Passive and the Legendary, I don't think Thorns wil work for Necro.
I mean, to make Thorns work you need something like the Invoker's set, which MASSIVELY boosts your thorns damage and gives it an offensive use. I can't see a Necro ThornPet build working, outside of MAYBE LoN, or some other very niche build.
^This, also not to mention Necros main stat is intelligence, therefore it will be missing about 15,000% dmg multiplier from the strength (rough estimate of average strength with about 1500 paragon) that a barb or crusader gets. Thorns WILL NOT be a viable build at least for anything remotely high level.
