My definition of an attack chain is a sequence of attacks you press repeatedly with little or no delay between them. Lightning Rod's base recharge is 90 seconds. The lowest you can expect to get it is around 25 seconds, which is not low enough for an actual attack chain. It is good for one or two uses per spawn of critters, usually.
The problem with Tenebrous Tentacles is that it is a cone. You would have to herd them, then line yourself up to hit all of the enemies at once. That takes a lot of time that you could be using to do damage. Without herding them, they would be too scattered to hit all of them in one cone or other AoE.
Ok, thanks! Helped me a lot to think about //darks usability.

Is this a good combo, elec/fire/dark? My plan was...
TT > Nightfall > LRod > Burn
That a good all around attack chain?
