Once your character reaches level 60 and begins pushing into Torment IV, the avenues for upgrading gear shift from finding new items to optimizing the gear you already possess. At this stage, your character's progression is driven by two systems: **Masterworking** and the **Paragon Board**.
Both of these systems require a significant investment of time and materials, meaning that optimizing your upgrades is vital for progression. In this guide, we will break down the mathematical models behind Masterworking probability, detail the scaling thresholds for Paragon Glyphs, and outline cost-effective strategies for optimizing your gear upgrades.
The Masterworking Upgrade Path
Masterworking allows you to upgrade an Ancestral item up to 12 times. Most levels provide a flat +5% increase to all stats on the item. However, at levels 4, 8, and 12, the item does not receive the standard 5% bonus; instead, a single random stat on the item receives a flat +25% increase (noted by a color change to Blue, Yellow, or Orange, respectively).
Because these 25% upgrades (or "crits") target a random stat, the probability of hitting a specific stat multiple times is subject to binomial distribution. If an item has 4 stats, the chance of hitting your desired stat on any single critical level is 1/4 (or 25%).
The Combinatorics of "Triple Critting"
For endgame builds, hitting your desired stat multiple times (such as triple-critting Cooldown Reduction on an amulet or critical strike chance on gloves) is key to scaling your performance. The probability of hitting your desired stat across the three critical levels is calculated as follows:
- Single Crit (1/3 desired rolls): The probability of hitting your desired stat at least once out of three attempts is:
P(≥1) = 1 - (3/4)^3 = 1 - 0.4219 = 0.5781 (or 57.8%) - Double Crit (2/3 desired rolls): Using binomial expansion, the probability of hitting your desired stat exactly twice is:
P(2) = 3 × (1/4)^2 × (3/4) = 3 × 0.0625 × 0.75 = 0.1406 (or 14.1%) - Triple Crit (3/3 desired rolls): The probability of hitting your desired stat all three times is:
P(3) = (1/4)^3 = 0.0156 (or 1.56%)
A 1.56% probability means that, on average, you will need to upgrade and reset an item **64 times** to hit a triple crit on a specific stat. This makes understanding the materials cost and resetting at cost-effective thresholds essential for managing your resources.
To simulate your upgrade paths and calculate the materials required for different setups, you can use our Masterwork Crit Upgrade Calculator.
Cost Optimization Strategy: The Reset Threshold
Because the gold and materials cost of Masterworking increases with each tier, resetting an item at later levels is highly inefficient. If you are targeting a double or triple crit on a specific stat, we recommend following this progression:
- Upgrade the item to Level 4. If the 25% upgrade does not hit your desired stat, **reset the item immediately.** The cost to reset at Level 4 is minimal compared to later levels, and you have a 25% chance to succeed on your next attempt.
- Once you hit your desired stat at Level 4, proceed to Level 8. If the second upgrade misses, evaluate your resources. If you are targeting a triple crit, reset. If you are content with a double crit (which has a 14.1% probability), you can keep the item as is or proceed to Level 12.
- Only proceed to Level 12 if you have secured your desired upgrades at levels 4 and 8. Attempting to hit a desired stat at Level 12 after missing the first two upgrades is inefficient, as the cost of upgrading from 9 to 12 is the most expensive phase of the system.
Paragon Glyph Scaling and Radius Thresholds
While Masterworking upgrades your gear, Paragon Glyphs scale the stats within your Paragon boards. Glyphs scale in power as you level them up using experience earned by completing Pit runs.
Glyphs feature two primary milestones that impact your board layouts:
1. Radius Expansion at Level 15
When a Rare Glyph reaches Level 15, its radius of influence on the Paragon board expands. For most glyphs, this increases the radius from 3 nodes to 4 nodes.
This expansion increases the number of active nodes within the glyph's area, making it easier to meet the stat requirements for the glyph's secondary bonus (such as "+40 Willpower within range"). The additional nodes also scale the glyph's primary stat multiplier, providing a significant boost to your build.
You can model your glyph radius requirements and calculate your stat coverage using our Paragon Glyph Scaling Calculator.
2. The Multiplicative Threshold
Many Rare Glyphs offer a secondary bonus that acts as an independent multiplicative modifier (e.g., "deals 10% [x] increased damage"). Meeting the stat requirements for these bonuses is a priority when pathing through your boards. Stacking glyphs that offer multiplicative bonuses is often more effective than pathing to flat additive nodes, as the multiplicative bonuses scale your entire character's damage output.
Gearing and Progression Milestone Comparison
To help you manage your progression, the table below compares the stat returns and resource requirements of different upgrade tiers in the endgame.
| Upgrade System | Progression Stage | Primary Benefit | Estimated Materials / Gold Cost | Priority Level |
|---|---|---|---|---|
| Masterworking 4/12 | Early Torment I | +20% base stats, 1x 25% Crit | Minimal (Obtained via low Pit runs) | High (Cheap and immediate power boost) |
| Glyphs to Level 15 | Torment II | Radius expansion, active secondary bonuses | Low (Farmed in Pit Tier 20–40) | Very High (Unlocks key build synergies) |
| Masterworking 8/12 | Torment III | +40% base stats, 2x 25% Crits | Moderate (Farmed in Pit Tier 50–70) | High (Provides defense needed for Torment IV) |
| Glyphs to Level 21 | Torment IV | Maximum stat scaling and bonus values | High (Farmed in Pit Tier 80+) | Moderate (Final optimization phase) |
| Masterworking 12/12 | Torment IV Endgame | +60% base stats, 3x 25% Crits | Very High (Requires Pit Tier 100+ materials) | Low (For min-maxing and speed running) |
Step-by-Step Optimization Process
To optimize your endgame upgrades, we recommend following these steps:
- Get all active glyphs on your Paragon boards to Level 15. The radius expansion is a priority upgrade that helps you meet stat requirements and scales your primary multipliers.
- Upgrade your core gear pieces (weapons, chest armor, pants) to Masterworking 4/12. Reset if the Level 4 upgrade does not hit a core stat (such as Cooldown Reduction or Crit Chance).
- Once your core gear is optimized at 4/12, push your glyphs to Level 21 to maximize their stat scaling.
- Finally, upgrade your gear pieces to 8/12 and 12/12. Target double or triple crits on your most important stats to optimize your build for high-tier speed running and Pit pushes.
