So, i couldnt find any official DRK post to ask this on so hopefully is quick and easy:

Delirium Blade: everyone says this is a dps increase or this is your most potent regular combo, but in the tooltip all it says is it reduces int by 10%. It has less potency than the enmity combo ender. Where is the dps increase in this?

Dark Mind: Good examples of magic damage worth saving this for? Im not a savage tank, only 186 atm. So any fights up to Rav ex and a4 norm.

Thanks in advance for the responses.
