More Path of Exile navel-gazing and chin-scratching:
Elemental Overload
Shaman's Dominion
So with both skills, for 4 seconds after summoning a totem, your brands have an almost guaranteed 40% damage boost? Although, it doesn't tell you how long the Elemental Overload boost lasts, and I'm not sure how that +40% compares to the critical strike multiplier you'd be getting if you don't have Elemental Overload.
Elemental overload lasts 8 seconds (the
Wiki is pretty good on things like that).
Increased crit chance is applied to the base chance, which is dependent on the weapon or spell being used, but is usually around 5-6%. So with 150% increased chance, you're on 15-18% to score a critical. That said, with brands, you probably don't need any other effects to keep Elemental Overload up pretty much all the time - brands hit fast, especially Storm Brand. When you've got 5 brands firing multiple times a second, even a 6% chance to critical is generally enough. As such, I probably wouldn't bother with Shaman's Dominion if you take EO, especially as, as I pointed out in my last post, Brands and Totems aren't that synergistic, as generally you want either Runebinder or Ancestral Bond respectively. You could used a Decoy Totem in your brand build with the multiple totem support if you really want to go for Shaman's Dominion, but that would be more for a full on crit build instead of elemental overload, and even then, you're probably only going to use it on bosses.
The general rule on Ele Overload is that it's a cheap and easy damage boost for casters. Full crit. based builds are better at the very top end, but get much more expensive in terms of both gear and passive points.
This is the skill tree on my Armageddon Brand character. She's an elementalist (witch ascendancy), but it could easily be adapted for a heirophant (just change the half a dozen or so nodes from the start point) and/or storm brand (only the fire and AoE nodes would want to be changed). AB is my main skill for both clearing and bosses, though I have Flammability and Vaal Righteous Fire to help out on tougher foes. Other than that, I have Flame Dash and Brand Recall linked to Arcane Surge and Faster Casting plus a CWDT setup with Immortal Call and a golem. I've been player her Solo Self Found, and am up to yellow maps without any real problems. I spent a bit of time farming a Tabula Rasa in the Blood Aqueduct (Act 9), but other than that, my gear's pretty junk.
Is there any way to play Path of Exile as casually as one would play Torchlight? I enjoy wading through hordes of enemies without really worrying about build and whether or not I'll immediately die, but based on all the build talk it sounds like it's more of a rogue-like where if you dare mess up a single component of your spreadsheet you're doomed to perma-failure.
Fortunately, there's loads of guides for builds. If you want to simply go and kill stuff, follow one of them. It's only when you want to start being creative and do your own thing that you need to delve into the mechanics. The passive tree I linked above shows how complicated it
can be, but it's not hard to simply follow what someone else has done.
