Season 15 (Patch 3.2.0) adds Challenge Dungeons — a brand-new overland boss activity that sits beside the Pit as a top-tier source of Paragon XP. With S15 expected to launch ~September 15, 2026, players who understand both routes before day one will hit Paragon 200 and max their Glyphs weeks ahead of the field. This guide covers the fastest Season 15 Paragon leveling loop, including when to run Challenge Dungeons vs the Pit, which Soul Splinter to socket, and which classes pull ahead in 3.2.0.
Quick answer (TLDR): In Season 15, the fastest Paragon loop is Challenge Dungeons for bulk XP (push 3 Torment tiers above your gear level for maximum reward density) + Pit runs for Glyph XP (the Pit remains the only source of Glyph upgrades). Equip the Soul Splinter of Anguish (+35% Crit Chance & Attack Speed) in one of your jewelry sockets to shorten kill times by roughly a third. Rogue leads the class rankings after the 3.2.0 balance pass; Barbarian took a significant nerf and is no longer the default pick. Read on for the full breakdown, including the optimal daily loop and which Pit tier to push.

How Does Paragon Leveling Work in Season 15?
Paragon Boards unlock once you reach the character level cap. Each board is a grid of bonuses — Stats, Magic, Rare, and Legendary nodes — that you fill out with Paragon Points earned through play. Glyphs are rare socket items you slot into special Glyph sockets on the boards; they multiply the value of surrounding nodes and are upgraded exclusively in the Pit.
Season 15 keeps this core loop but adds three meaningful changes:
| Change | What It Means for Paragon Farming |
|---|---|
| Challenge Dungeons (new) | Second XP-dense activity alongside the Pit; scales difficulty 3 Torment tiers above your current setting |
| Soul Splinters (new) | Jewelry socketables that boost kill speed or survivability — directly affects runs/hour |
| Spiritborn Swarm of Storms board (new) | Brand-new Paragon Board for Spiritborn players unlocking minion + storm synergies |
All S15 mechanics are based on the 3.2.0 PTR (concluded August 11, 2026). Final tuning will be confirmed at BlizzCon 2026 (September 12–13) and at launch.
How Do Challenge Dungeons Work in Season 15?
Challenge Dungeons are accessed through portals that spawn in overland zones. Entering one drops you into an escalating boss fight. The key mechanic for farmers: you can voluntarily raise the dungeon's difficulty up to 3 Torment tiers above your current setting. Higher tiers yield proportionally better rewards — more XP, better loot, and more crafting material — but the boss scales up accordingly.
On the 3.2.0 PTR, Blizzard explicitly flagged Challenge Dungeons as a tuning target. Per their official PTR notes (news.blizzard.com/24292852): "We have more to share at BlizzCon, and we didn't want all that's coming with Season 15 to be available before we get a chance to talk more about it" — which means exact XP numbers remain provisional.
Why Challenge Dungeons Beat Open-World Grinding
Open-world content (Helltide, War Plans) rewards normal monster density with standard XP. Challenge Dungeons compress a boss fight into 2–4 minutes with a boss kill that rewards a guaranteed high-quality drop loot package on top of substantial XP. At T+3 tiers above gear level, the XP-per-minute density exceeds most open-world alternatives, particularly for classes with strong single-target burst.
How to Push Tier Efficiently
Practical tier-pushing rules for Challenge Dungeons:
- Start at T+1 above your Torment. If you clear it in under 3 minutes, push to T+2 next attempt.
- T+3 is the ceiling (max difficulty boost per dungeon). At T+3, the XP reward is roughly 2–2.5× a flat-difficulty run.
- Wipe = tier loss. Failed attempts don't grant XP. Stay at the tier you can clear consistently.
- Pair with the Overland Ambush: the new 30-second Ambush event (a demon hunts you) can spawn as you travel between Challenge Dungeon portals. Don't ignore it — killing the demon quickly yields bonus XP and materials.
Why the Pit Is Still Mandatory in Season 15
Challenge Dungeons give Paragon XP. They do not give Glyph XP. The Pit is still the only source of Glyph upgrades in Season 15. Running nothing but Challenge Dungeons will stall your build once you're board-filling — your Glyphs will be under-leveled, costing you 30–60% of their node-multiplier value.
The Pit Bubble — the end-of-run invulnerability window re-added in Patch 3.1.3 — carries over into S15 (per news.blizzard.com/24287406). It spawns on Pit completion unless a Whisper Ambush triggers; if an Ambush spawns, the bubble is suppressed until you kill the Ambush boss.
What Pit Tier Should You Target?
| Goal | Recommended Pit Tier |
|---|---|
| First Glyph upgrade (from 1 → 15) | Tier 46–60 |
| Steady Glyph leveling (mid-season) | Tier 70–90 |
| Max Glyph level grind (late-season, Paragon 200+) | Tier 100–130 |
| Personal record push | 130–145 (current S14 ceiling for most builds) |
Run the tier you can complete in under 2 minutes. Clearing one tier higher in 5 minutes gives less Glyph XP per hour than two fast clears at the comfortable tier.
What Is the Best Soul Splinter for Paragon Farming?
Soul Splinters are Season 15's new jewelry socketables (ring slots + amulet, up to 3 at once). They come in 5 rarities — Common through Unique — and can be upgraded in the Horadric Cube. For paragon farming, two splinters matter most:
| Soul Splinter | Effect | Use Case |
|---|---|---|
| Anguish | +35% Crit Chance, +35% Attack Speed; costs +30% resources/sec | Best for kill speed in both Pit and Challenge Dungeons |
| Sin | +40%[x] Max Health; −30% Max Resource | Use when attempting T+3 Challenge Dungeons before your gear is fully ready |
| Lies | +100% gold, +100% crafting mat drops, +25% XP; always Weakened+Vulnerable | Optional gold-farming rotation; the Vulnerable self-debuff is manageable at high paragon |
Splinter of Anguish is the default for paragon grinding. The +30% resource drain is real, but builds with strong resource generators (Rogue Combo Points, Sorcerer Flame Shield, etc.) absorb it easily. The kill speed gain outweighs the resource cost in nearly every scenario.
The Leoric's Crown Multiplier
Leoric's Crown (one of the 10 Legacy Uniques returning in Season 15) is a helm that counts as Jewelry in 3.2.0 — its effect amplifies socketed gem effects and Soul Splinter effects by 75–100%. Since it stays in the helm slot, it does not compete with your ring/amulet Soul Splinter sockets. If you land one, a Legendary Splinter of Anguish reads roughly 61–70% Crit Chance and Attack Speed (35% × 1.75–2.0). This is likely the single biggest paragon farming upgrade available in Season 15.
Note: Leoric's Crown is a permanent addition to D4 (all modes), not season-exclusive. All values are PTR-provisional.

Which Class Is Fastest for Paragon Leveling in Season 15?
Patch 3.2.0 reshuffled the class tier list significantly.
| Class | S15 Status | Paragon Notes |
|---|---|---|
| Rogue | Best overall | No significant nerfs; gained Tricks of the Trade Paragon Node (paragon-level damage boost for Combo Point spenders); fastest clear times on the PTR |
| Spiritborn | Very strong | New Swarm of Storms Paragon Board adds minion + storm synergies; still one of the game's highest damage ceilings |
| Druid | Solid buff | Stat scalar raised 1.25 → 1.625 in 3.2.0; significant damage output increase |
| Necromancer | Solid buff | Same stat scalar buff as Druid; Blood builds gain across the board |
| Sorcerer | Mixed | Stat scalar up 1.25 → 1.625, but fire builds nerfed; Ice Spike buffed |
| Paladin | Still behind | Gets Judicator tweaks in 3.2.0 but Maxroll's post-PTR summary rates it "still lagging behind by a fairly large margin" |
| Barbarian | Nerfed — avoid | Core Stat Scaler cut 1.1 → 0.8; Paragon Glyphs and Legendary Nodes cut 20–25%; Barbarian is not a top paragon grind pick in S15 |
If you're playing for paragon speed, Rogue is the safe top pick. Spiritborn players with access to the Swarm of Storms board will also clear quickly, but the new board needs testing at live parity.
The Optimal Season 15 Paragon Daily Loop
Once you're in Torment difficulty and actively Paragon grinding, rotate between these in priority order:
- Challenge Dungeons (T+2 or T+3 above current Torment) — run until you hit a natural stopping point or a portal cluster dries up
- Pit (at your comfort tier) — 5–10 runs to bank Glyph XP; don't neglect this or your boards will stall
- Helltide / War Plans — fills time between Challenge Dungeon portal spawns; secondary XP source
- Horadric Cube — upgrade your Soul Splinters when you have enough materials; Anguish Legendary is a major power spike
Upgrade your Anguish Splinter to Legendary tier as soon as possible. The difference in kill speed between Rare and Legendary Anguish is measurable enough to cut 20–30 seconds off a boss kill.

Frequently Asked Questions
Can you skip the Pit entirely in Season 15 by using Challenge Dungeons? No. Challenge Dungeons provide Paragon XP and loot, but they do not award Glyph upgrade experience. The Pit remains the exclusive source of Glyph leveling in Season 15. Running only Challenge Dungeons will leave your Glyph bonuses severely under-powered by mid-season.
What difficulty should I run Challenge Dungeons for maximum Paragon XP? Set the dungeon difficulty to T+3 above your current Torment setting (the maximum allowed). If you can't clear consistently in 3–4 minutes at T+3, drop to T+2. The XP bonus at T+3 is roughly 2–2.5× a standard-difficulty run based on PTR data.
Is Barbarian still good for paragon farming in Season 15? Barbarian took significant nerfs in Patch 3.2.0 — its Core Stat Scaler was cut from 1.1 to 0.8, and Paragon Glyphs/Legendary Nodes were cut 20–25%. It is no longer a top paragon grind pick; Rogue, Spiritborn, and post-buff Druid/Necromancer are all faster alternatives.
Does Leoric's Crown actually boost Soul Splinters? Yes, according to 3.2.0 PTR data. Leoric's Crown amplifies socketed gem effects and Soul Splinter effects by 75–100%. Since it stays in the helm slot, it does not compete with your ring/amulet Soul Splinter sockets. A Legendary Splinter of Anguish with a max-roll Leoric's Crown yields roughly 61–70% Crit Chance and Attack Speed (35% × 1.75–2.0). All values are PTR-provisional until BlizzCon confirms live tuning.
When does Season 15 start? Season 15 with Patch 3.2.0 is expected to launch around September 15, 2026, right after BlizzCon 2026 (September 12–13). Blizzard has not announced an official date; the ~September 15 timing is based on the in-game Season 14 Reliquary countdown and the standard ~77-day season cadence. Watch BlizzCon for the official launch confirmation.
