I'm reworking my ES build, and I had a few questions about how the way EB works as I look to planning out my ED levels.

As far as I looked I couldn't find any specific answer to these questions in the forums or elsewhere and I would appreciate any help from experienced warlock players.

1) Are the individual parts of my EB (base damage +pact+ES light) considered a separate spell? I noticed each part gets its own individual spell crit message in chat log. Do they proc spell effects (such as shiradi) individually?

2) I was looking at the tier 3 core for DI, if my pact is of the appropriate element would it trigger the temp Hp?

3) SD Paranoia imbues my harmful spells to do extra damage based on my sneak dice, but the way its worded is a little confusing to me, If its active and my aura hits 3 enemies, do they all take the extra damage or just one?

Any help would be much appreciated. Thank you.
