Key Takeaways
- Blizzard's November 6, 2023 Patch 10.2 PTR development notes set the rules for the Dragonflight Season 3 rollover, a Sanguine affix tweak, and a heavy nerf to the Undulating Sporecloak.
- At the Season 3 start on November 14, Mythic+ keystones dropped an extra 11 levels on top of the usual weekly reduction.
- An untimed +15 from the prior week landed at +3, and a timed +15 landed at +4, exactly as Blizzard's worked examples showed.
- Pools of Sanguine Ichor became connected, so crossing between adjacent pools no longer stacked an extra application of the affix.
- The Undulating Sporecloak, a crafted cloak embellishment, had its shield and healing cut by 79%, its Versatility by 75% above 70% health, and its heal-over-time by 80%.
Ahead of Dragonflight Season 3, Blizzard published a round of Patch 10.2 PTR development notes that spelled out how the Mythic+ season would reset and which items were getting reined in. The biggest talking points were the keystone decay at the rollover, a quality-of-life change to the Sanguine affix, and a steep cut to one of the most-used crafted embellishments. Here is how each landed when the season actually turned over.
The Season 3 Keystone Decay
When Dragonflight Season 3 began on November 14, 2023, every Mythic+ keystone took an additional 11-level drop alongside the normal weekly reduction. The goal was to keep the new season's early weeks challenging rather than letting players carry over end-of-season keys into a fresh affix pool.
Blizzard's two examples made the math concrete. If you finished a +15 the previous week but did not beat the timer, your key would normally fall one level to 14 for the untimed run, then the rollover knocked off 11 more, leaving you with a +3. If you timed that +15 instead, you kept the 15, and the rollover took it down to a +4. Either way, the whole community started the season at the bottom of the ladder together.
The Sanguine Affix Change
The notes also softened the Sanguine affix. Sanguine drops a lingering pool of ichor where a non-boss enemy dies, healing other enemies that stand in it and hurting players who do. Before the change, two pools that overlapped counted as separate hazards, so moving from one into the next reapplied the damage stack.
The update treated Pools of Sanguine Ichor as connected. Stepping between adjacent pools no longer applied an additional stack of the affix, which made dragging packs through tight rooms less punishing. It was a small wording change with a real feel improvement on the affix weeks it showed up.
The Undulating Sporecloak Nerf
The headline item change hit the Undulating Sporecloak, a Dragon Isles Tailoring back-slot embellishment rather than a shield-slot item. Its proc healed you while you stayed above 70% health, then burst into a large absorb when you dropped below 30%, which made it a defensive staple in high Mythic+ keys through Season 2.
The nerf arrived in two stages, and the gap is where the confusing "(previously 50%)" line comes from. An earlier PTR build simply halved the shield. The final build, set in the November 6 notes, went much further: it cut the shield and healing by 79%, trimmed the Versatility bonus by 75% while above 70% health, and dropped the heal-over-time effect by 80%. Blizzard said the new Versatility bonus had been delivering more throughput than intended, so the deeper cut pulled the cloak back in line with other profession embellishments while keeping its above-70%-then-below-30% rhythm intact.
📌 A common mistake at the time was quoting the early "shield halved" number as final. That was a mid-PTR snapshot; the live 10.2 build cut the shield and healing by 79%, so the cloak ended up far weaker than the first datamine suggested.
FAQ
How much did keystones drop at the start of Season 3?
Mythic+ keystones dropped an additional 11 levels at the November 14, 2023 season rollover, on top of the normal weekly reduction. That reset the ladder so everyone restarted the season from low keys rather than carrying high ones across.
What did a +15 key become after the rollover?
It depended on the timer. A +15 completed but not timed the prior week first fell to 14, then the 11-level rollover left it at +3. A +15 that was timed kept its 15 and dropped to +4 after the rollover.
What changed about the Sanguine affix in Patch 10.2?
Pools of Sanguine Ichor became connected. Moving between adjacent, overlapping pools no longer applied an extra stack of the affix, which made pulling enemies through clustered Sanguine pools less dangerous than it had been.
Why was the Undulating Sporecloak nerfed so hard?
Its added Versatility bonus produced more damage throughput than Blizzard intended. The final 10.2 build cut the shield and healing by 79%, the Versatility by 75% above 70% health, and the heal-over-time by 80%, keeping it a defensive option without out-valuing other embellishments.
What does "(previously 50%)" mean in the patch notes?
It refers to an earlier PTR pass that only halved the Undulating Sporecloak's shield. The final live build replaced that with the steeper 79% cut, so the "(previously 50%)" note marks the mid-PTR value, not the shipped one.
Do these Patch 10.2 changes still apply today?
No. These were Dragonflight Season 3 changes from late 2023, long replaced by newer seasons and item tuning. Read them as a record of that PTR cycle, not as guidance for the current Mythic+ pool or crafting meta.
If you want a clean timed key without fighting a bricked run, you can compare our Mythic+ dungeon boosts and pick the level you need.
