My Edlen Ring Arcana Run - Build Spoilers

We're going for the Bloody Helice. It's requirements are

Later we'll also want Eleonora's Poleblade. It's requirements are

We also want some incantations and the Mimic Tear. As per the run, at Level 43 we want to be at:

To cover all the basis, including a decent equip load/stamina gauge.

Reasoning: Eleonora's Twinblade is ... nice. But I somehow prefer the basic Twinblade because we can put the Bloody Slash Ash of War on it. However, we'll be able to Level Elonora's Twinblade to +9 way before we can get the basic Twinblade to a comparable Level - and so is that.

As for the Bloody Helice, it's firstly to get away from just doing a Greatsword build - or something equivalent. It isn't slow as a Colossal (high Str) weapon while for speed we have the twinblade. Heavy Thrusting Swords deal great stagger damage - and that's the main reason why we'd use anything but the twinblades. A second one being range.
The Heavy Thrusting Sword staggers faster than a Greatsword - so, if we need to rely on getting charged heavy attacks in, this is the way to go. Also, it's weapon art isn't bad. It's essentially a dodge that costs mana that can be followed up with essentially a heavy thrust. It feels equivalent to a charged attack. All that without the charging time of either a charged or uncharged heavy attack. And that's really useful in a few instances. It's very fringe ... but ... useful.
As the biggest downside I think the problem is that after using the dodge, one might feel they're not getting the full return out of the mana spent and thus greed for a follow up attack, which can ... take one right into harms way.

It's nice to learn a few things about dodging.
