What Is Protocol 0 and Why Starforge Stones Are Everything
Protocol 0 is a limited-time event built around the Dravion X-Suit — one of the most visually elaborate cosmetics in the current lineup. You have exactly 54 days to acquire the suit and push it through seven upgrade tiers. Once the timer hits zero, the event closes permanently. No reruns, no second chances.
Starforge Stones are the primary upgrade material across all seven tiers. A secondary material — Star Fragments — is also required at certain tiers, but Starforge Stones are the bottleneck resource. Running out mid-event means stalling at an incomplete tier, wasting the base acquisition cost you already spent.
Upgrade Costs at a Glance
- Single Lucky Spin draw: 60 UC
- 10-draw bundle: 570–600 UC
- Full 300-draw base acquisition: ~6,000–8,000 UC
- Full Level 7 completion (total UC range): 80,000–150,000 UC depending on suit
- Stygian Liege X-Suit (reference): 150,000 UC for 7 stars
- Galadria X-Suit (reference): ~100,000 UC for full upgrade

Every Starforge Stone Source in Protocol 0
Daily Missions — Your Core Income
Daily missions are the most consistent renewable stone source across the 54-day window. Every day you skip is a permanent loss — there's no catch-up mechanic for missed resets. Complete all available dailies before the reset timer, even partial completion compounds meaningfully over 54 days.
Login Streak Bonuses
Consecutive logins deliver bonus stones at milestone days (Day 7, Day 14, Day 21, etc.). Breaking your streak resets the bonus track. The login bonus alone won't max your suit, but missing streak milestones creates a deficit that forces harder grinding or extra UC spending later. Set a daily reminder if needed.
Challenge Missions — One-Time, High Yield
Challenge missions pay out more stones than dailies and complete once. Typical objectives include:
- Reaching specific placement thresholds in matches
- Accumulating kills or assists during the event period
- Completing Protocol 0-specific objectives
- Participating in designated game modes
Complete these as early as possible. Front-loading your stone balance gives you flexibility in the final weeks.
Time-Limited Bonus Windows — Don't Miss These
Certain 24–72 hour windows activate during the event, offering multiplied stone rewards for specific mission types. These are the highest-efficiency farming opportunities in the entire event — and they appear without advance notice.
Check the Protocol 0 event interface every morning. These windows expire before most players realize they existed.

UC-Linked Stone Sources
Lucky Spin draws are the primary UC-linked source. Always use the 10-draw bundle (570–600 UC) over single draws (60 UC each) for better per-draw value. Certain cumulative spend milestones also unlock bonus Starforge Stone packages, effectively reducing your per-stone UC cost if you're already planning to spend.
How to Farm Starforge Stones Fast: Optimized Routine
Two Sessions Beat One Long Session
Mission resets follow UTC+0 timing — identify your local reset time on Day 1. The optimal approach: complete dailies immediately after reset, then log back in before the next reset to catch bonus window activations. Two short sessions per day consistently outperform one long session in stone efficiency.
Stack Overlapping Mission Objectives
Some missions share completion conditions — a single match can simultaneously progress multiple tracks. Identify overlapping objectives and complete them in parallel rather than sequentially. This reduces total playtime by 20–30% while maintaining the same stone output. Across 54 days, that's significant.
Your Daily Minimum Target Formula
Reverse-engineer your daily target:
- Determine total stones required for your target tier
- Subtract stones already accumulated
- Divide remainder by days remaining
- That number is your daily minimum
Recalculate every 7 days to account for bonus windows and missed sessions.
Recovery Strategy After Missing Days
Missing one day is recoverable. Missing three or more creates a deficit requiring:
- Completing all available challenge missions immediately
- Targeting every active time-limited bonus window
- Supplementing with UC-linked stone purchases to close the gap
Don't abandon the event after missing days — even Level 3 unlocks the Dravion's wing activation and glowing helmet crest, which is a meaningful visual upgrade worth reaching.
X-Suit Upgrade Guide: Every Tier Broken Down
How to Access the Upgrade Interface
- Open Inventory
- Navigate to Outfits tab
- Select the Dravion X-Suit
- Tap Upgrade
The interface shows your current stone balance, next tier cost, and a preview of visual changes at each level.

What Each Tier Unlocks
- Level 1: Base armored appearance with scale detailing

- Level 2: Enhanced armor detailing, activated glow segments
- Level 3: Wings activate, glowing helmet crest — first major visual milestone
- Levels 3–6: Dragon Transformation Mode with progressive fire effects
- Level 6: Fully realized Dragon Transformation — visual peak for most players
- Level 7: Maximized effects, animations, and exclusive two-player glider
Best Value Tier — Honest Assessment
Level 3 is the first meaningful visual threshold. Level 6 delivers the complete Dragon Transformation — the signature look most players associate with the Dravion. Level 7's exclusive unlock is the two-player glider, a functional cosmetic unavailable through any other path.
For budget-conscious players: Level 6 delivers ~90% of the visual impact at a lower total stone cost. For players going all-in: Level 7 is the logical endpoint.

Free-to-Play Strategy: How Far Can You Go?
Realistic F2P Ceiling
The base X-Suit acquisition requires 300 Lucky Spin draws — fundamentally UC-gated. F2P players who already own the suit can upgrade using free stones from missions and login bonuses. Realistic F2P target through mission grinding alone: Level 3 to Level 5, depending on daily consistency across 54 days.
F2P Mission Priority Order
- One-time challenge missions — highest stone yield, complete immediately
- Login streak bonuses — zero playtime required, never skip
- Daily missions with overlapping objectives — maximize stones per minute
- Time-limited bonus windows — treat as mandatory when active
F2P Milestone Checklist
- Day 1–7: Complete all one-time challenges, establish login streak
- Day 8–21: Maintain daily missions, bank stones toward Level 3
- Day 22–40: Target Level 4–5 using accumulated stones
- Day 41–54: Final push using remaining bonus windows and streak rewards
Smart UC Spending: Maximize Stone Returns
Bundle Math
Always use 10-draw bundles (570–600 UC) over single draws (60 UC). The S10 bundle pricing at 570 UC is slightly cheaper than S8's 600 UC — use the cheaper option when available. Purchase milestone bonuses triggered at cumulative spend thresholds deliver additional stones that reduce your effective per-stone UC cost.
14-Day Final Push Schedule
For players entering mid-event or making a final push:
- Days 1–3: Complete all remaining one-time challenge missions
- Days 4–7: Maintain dailies, prioritize active bonus windows
- Days 8–11: Stack overlapping objectives for maximum efficiency
- Days 12–14: Final stone push — use UC-linked purchases if needed to close the gap
Pro tip: Plan your schedule assuming you'll miss 3–5 days across the event. Build that buffer into your daily target from Day 1. Players who plan for perfect attendance and miss sessions end up in deficit; players who plan for imperfect attendance and exceed it end up with surplus stones.
4 Mistakes That Kill Your Protocol 0 Progress
Mistake 1: Ignoring time-limited missions Bonus windows expire without warning. Missing 2–4 windows across the event creates a compounding stone deficit. Fix: Check the event interface daily at the same time each day.
Mistake 2: Spending stones on secondary event shop rewards Stones spent on non-upgrade rewards can't be recovered. Some players deplete their upgrade budget without realizing it. Fix: Calculate your total upgrade stone requirement first. Only spend on secondary rewards with a confirmed surplus.
Mistake 3: Upgrading without confirming you can reach the next visual milestone Upgrades are sequential — you can't skip tiers. Getting stuck between milestones wastes resources. Fix: Before upgrading, verify you have enough stones to reach Level 3, Level 6, or Level 7 — whichever is your next target.
Mistake 4: Not tracking your daily stone balance Players who don't track discover they're 20–30% short in the final week with no recovery time. Fix: After each session, note your stone balance and compare against your daily target. Adjust mission priority the next day if you're falling behind.
Frequently Asked Questions
Q: What are Starforge Stones? The primary upgrade currency for the Dravion X-Suit. Every upgrade from Level 1 through Level 7 requires them. They're the central resource determining how far you push your X-Suit before September 30, 2025.
Q: Can I get the Protocol 0 X-Suit for free? Base acquisition requires 300 Lucky Spin draws at 60 UC each — it's UC-gated at the acquisition stage. Players who already own the suit can upgrade using free stones from missions and login bonuses, but obtaining the base suit without UC isn't feasible through standard event mechanics.
Q: How many upgrade tiers does the Dravion X-Suit have? 7 tiers. Level 3 activates wings and the glowing helmet crest. Levels 3–6 engage Dragon Transformation Mode with progressive fire effects. Level 7 unlocks the exclusive two-player glider and maximized animations.
Q: When does Protocol 0 end?September 30, 2025. The event launched August 8, 2025 — 54 days total. After this date, the event closes and upgrade progress locks permanently.
Q: Do Starforge Stones expire after the event? Yes. They're event-specific currency tied to Protocol 0. They don't carry over to future events or convert to other currencies after the deadline.
Q: Is maxing to Level 7 worth the UC investment? Level 7's exclusive two-player glider isn't available through any other means. For players who value exclusive time-limited cosmetics, it's justified. For casual players, Level 6 delivers the full Dragon Transformation at lower total cost — the best value tier in the progression.
Don't let the Protocol 0 event close before you hit your target tier. Top up UC instantly and securely at buffget — more stones, more upgrades, more value before the September 30 deadline.
