What Are PPC Skulls and Why Do They Matter
Phantom Pain Scars or PPC Skulls are a premium endgame currency mainly obtained from the Phantom Pain Cage (PPC). They play a vital role in both construct promotion and weapon enhancement.
Here’s what they’re used for:
- Character Shards - 500 PPC Skulls can be exchanged for 30 shards of a specific S-rank construct, enough to promote them from S to SS rank. Each character’s shard purchase is limited to 30 and does not refresh. This is a highly efficient investment since a character dupe equals 30 shards, meaning you can effectively skip pulling a duplicate from the gacha by purchasing shards through the PPC shop instead.
- Weapon Accelerators - Each costs 25 PPC Skulls, and 25 Accelerators are required for Weapon Harmony, a system that unlocks two additional memory slots per character.
It’s best to buy shards first for long-term account progress, then shift your focus to weapon accelerators once your main characters are fully ranked and harmonized. Managing your PPC Skull spending carefully ensures steady growth without wasting this limited resource. With consistent farming and smart usage, PPC Skulls can dramatically reduce the amount of gacha investment you need for future upgrades.
1. Clear the Phantom Pain Cage Weekly
Phantom Pain Cage (PPC) is the main source of PPC skulls in Punishing: Gray Raven. PPC rotates 3 bosses every week, each with a specific elemental or affix weakness. Using teams that counter these weaknesses is essential for earning high scores and maximizing your Skull rewards.
Check the weekly boss rotation before entering and build elemental teams that match the bosses’ vulnerabilities. Upgrading your weapons and optimizing memory sets can make a noticeable difference in performance and point gain.
Even if you can’t reach top ranks, completing all three bosses every week provides a steady flow of PPC Skulls. Over time, these consistent clears add up, helping you gather enough Skulls for construct shards and weapon enhancements without relying on limited events or top-ups.
2. Challenge the Phantom Pain Cage Outlier
The PPC Outlier mode provides another excellent opportunity to collect PPC Skulls. It’s a collection of older bosses that have been cycled out of the main PPC rotation but remain permanently accessible.
Each Outlier boss gives up to 50 or more PPC Skulls when you reach their required point threshold. These modes allow players to revisit previous content, refine team strategies, and earn extra rewards without worrying about weekly resets.
TIP: Focus more on outlier bosses that match your strongest teams’ element to easily clear stages and reach the score requirements. This approach helps you practice your rotations while steadily building up your Skull reserves. Over time, the Outlier system becomes a great way to test your progress, and finishing all Outlier challenges gives a noticeable boost to your overall Skull count.
3. Reach Top-Up Milestones
Top-up milestones are another way to earn PPC Skulls while gaining additional upgrade materials. Each Rainbow Card purchase contributes toward milestone rewards that include PPC Skulls, character shards, weapon shards, weapon selectors, and more.
Every purchase counts toward your next milestone tier, making this a very good option for players who plan to support the game financially. During integrated patches or anniversary events, milestone rewards are often upgraded, providing extra incentives to recharge during those periods. Taking advantage of these limited-time promotions gives plenty of PPC skulls, helping you reach your upgrade goals faster without relying purely on weekly farming.
