There's definitely a messy history here. Our aim throughout has been to provide a more consistent experience, but there have been other bugs exposed as we applied various fixes in pursuit of that goal, which required new fixes, and so forth. Fingers crossed, but we think we're at a final state at this point.
The core of the original problem lay in Dia's nature as a Shadow-school-exclusive caster with a variety of spells, one of which (
Seta Caótica) needed to respect school lockout when interrupted, and
Marca do Necromante's exponential growth that makes
Ceifar timing very important.
A history of changes here:
Original state:
Face do Pesadelo respected school lockout, and because
Ceifar could not be cast during
Face do Pesadelo, the exact timing and quantity of
Seta Caótica interrupts could cause huge variance in
Ceifar's timing, and thus the damage taken from
Marca do Necromante. Some players figured out an exact interrupt order to reliably cause Reap to be delayed so that it started coming after Mark, pretty much trivializing Mark for the rest of the fight.
Reap Hotfix #1 (August 3): Because it was a problem that the danger posed by Mark/
Ceifar could vary drastically from pull to pull, we made Visage ignore school lockout, which made its timing more predictable, and thus
Ceifar's timing as well. We realized that many guilds had only killed the fight by manipulating the timing to get the optimal
Ceifar/Mark order, so we also nerfed Mark damage at the same time to help offset the potential increase in difficulty.
Post-Hotfix #1: This mostly addressed the problem, though quirks in AI timing meant that it was still rarely possible to get the "easy" spell order. The new timing exposed an even worse bug, however. Dia could not
Ceifar while
Trevas was occurring. Previously, delayed Visage casts tended to cause these two abilities to not intersect. But after our hotfix, there was a predictable window, about 6:30 into the fight, where they would line up, and the result was to delay Dia's fifth
Ceifar by a significant amount, causing Mark damage to ramp out of control and almost certainly cause a wipe. Not good.
Hotfix #2 (August 11): We fixed the issue with
Trevas preventing
Ceifar, and rebuilt the way
Ceifar/Mark work, and now force Dia to re-cast Mark after each
Ceifar so that they can never get desynced and the variance in Mark damage from pull to pull should go way down.
Post-Hotfix #2: The change to
Trevas/
Ceifar interaction also increased the effective duration of
Trevas (a side-effect, not the core intended change), which increased the damage and positioning disruption from that ability.
Hotfix #3 (August 13): We're going to be reducing the duration of Darkness to match how it used to be prior to Hotfix #2.
We're generally hesitant to buff fights once they're in the wild, and didn't set out here with the intent of making the encounter strictly more difficult (hence the offsetting nerf to Mark damage in Hotfix #1 above). The goal was always to reduce large variation in the fight's difficulty from pull to pull, which makes for a frustrating experience. There were admittedly a few more pitfalls along the way than we expected. Please let us know if you continue to experience any frustrations or apparent bugs here.
