Multi-flares are also much harder to achieve now that we don't have an MP potion that can restore enough to trigger it with the MP levels at 60 cap. A HQ X-Ether won't even do it. Convert will, of course, so the max you're probably going to want to pull off at full Astral strength is going to be two.

That said, with Blizzard IV and trying to maintain Enochian, the need to do back to back Flares is significantly reduced since the rotation has to be compacted into that 30 second interval anyway.
