Heads-up for the low level cursed Bind Demon

Hey all, I'd like to share my experience about Bind Demon. This ladder I decided to play Chaos Warlock but want always a demon companion. That's why I decided to get Grotesque as my demon pet and waited for River of Flame to be TZed and even cursed. Then got it. It didn't work of course not well since the proc chance deeply nerfed but in any case it was a nice meat shield with extra 5 small ones. Then, I came across another TZed River of Flame and right before I found a Bloodpact Shard, which gives me 15 Bind Demon points (soft) and which means additional spectral hit. I decided to give it a chance to get the same demon with an additional skill, got it at first try and voila! Spectral hit gives it much more proc chance!

I wanted to share in case another player want to benefit from it, how this bad boy help me.

Special Hit gives "chance to hit x2". Maybe it's the reason. Although I don't really know what it means, adding attack rate or actual hit number x 2, either way it helps getting curse up faster.

Spectral hit doesn't give any additional attack like Mirrored Blades or Echoing Strike, nor does it add AR. Despite the name, it just adds elemental damage and resistances (possibly even immunities):

Spectral Hit:
Bonuses are applied individually in the following order if Resist <75%:
Cold Resist: +40%
Fire Resist: +40%
Lightning Resist: +40%
Pick from Magic, Fire, Lightning, Cold and Poison and do:
Element Minimum Hit: +66% damage
Element Maximum Hit: +100% damage
Cold or Poison Length is 1.6 seconds

I respect the knowledge from ClassicBattleNet, but I want to say that the +40% res in Spectral Hit might be wrong, +20% res I think. A few websites stat that it is +20% res, like Diablo Wiki, theamazonbasin etc. They also mentioned chance to hit x2, but I really don't know this one.

Like I said, I don't know why but it works much better.
