Gem Spending Guide — Optimal Allocation, Priority Purchases & ROI
Where to spend gems for max ROI, priority order, banner value analysis, trap purchases, F2P vs whale strategies.
Quick Answer: Where Should I Spend My Gems?
Priority Order (Memorize This):
- Legendary Banner 10x (10,000 gems) — Until Main DPS + Healer + Tank obtained
- Unit Slots (50 gems per 5) — Expand to 150+ ASAP
- Trait Rerolls (50 gems each) — Main DPS only, AFTER 3 free dailies
- Save — 50k+ for next major banner / emergency
NEVER Buy: Mythic Banner, Gold, XP Boosts, Cosmetics, Stamina/Energy

Purchase Priority Analysis
1. Legendary Banner 10x Pull (10,000 Gems) — ★★★★★ HIGHEST ROI
Expected Value per 10x Pull
| Outcome | Probability | Value | Notes |
|---|---|---|---|
| Legendary Unit | ~65% (1-2 per 10x) | 50,000+ gems equiv | Carries account |
| Mythic Unit | ~5% | 500,000+ gems equiv | Jackpot |
| Epic Units | ~30% | Fodder/Collection | Evolution mats |
| Rare/Common | Filler | Scrap | Negligible |
Pity System
- Soft Pity: 70 pulls (Legendary rate increases)
- Hard Pity: 90 pulls (Guaranteed Legendary)
- Mythic Pity: 180 pulls (Separate counter, not worth chasing)
When to Pull
- Always: You lack Main DPS / Healer / Tank
- Always: New meta unit released (check tier list)
- Stop: You have Sukuna/Gojo/Natsu + Elizabeth + Escanor + 2 Flex
ROI Calculation
Cost: 10,000 gems
Expected: 1.3 Legendary units per 10x
Value per Legendary: 50,000+ gems (account progress)
ROI: 6.5x minimum, ∞ if Mythic hit2. Unit Slots (50 Gems per 5 Slots) — ★★★★★ ESSENTIAL INFRASTRUCTURE
Breakpoint Analysis
| Slots | Cost | Purpose | ROI |
|---|---|---|---|
| 50 | 500 gems | Story units + Codes + 2 teams | ∞ (Required) |
| 100 | 1,000 gems | 4 teams + Fodder + Collection | ∞ (Required) |
| 150 | 1,500 gems | Raid teams + Alts + Fodder buffer | High |
| 200 | 2,000 gems | Whale/Collection | Medium |
| 250+ | 2,500+ gems | Completionist | Low |
Why Slots > Pulls (Early Game)
- No slots = Can’t claim code units = Waste 30k+ gems worth of codes
- No slots = Can’t hold raid fodder = Can’t evolve units
- No slots = Sell Legendaries = Permanent account damage
Rule: Buy slots proactively — when at 80% capacity, buy next 50.
3. Trait Rerolls (50 Gems Each) — ★★★★☆ HIGH ROI (Targeted Only)
Economics
| Scenario | Cost | Expected Result | Worth It? |
|---|---|---|---|
| Free Dailies (3/day) | 0 | 1 Legendary/30 days | ALWAYS |
Paid: Main DPS to Divine | ~1,000 gems (20 rolls) | Divine Locked | YES |
Paid: Main DPS to Requiem | ~10,000 gems (200 rolls) | Requiem Locked | Endgame only |
| Paid: Support/Tank | 500-2,000 gems | Legendary trait | After Main DPS done |
| Paid: Sub Units | Any | Any | NO |
Reroll Decision Tree
Is this your MAIN DPS (Sukuna/Gojo/Natsu/Levi/Arthur)?
│
├─ YES → Use 3 free daily → Stop at `Divine` (Legendary) → Lock (100 gems)
│ └─ If endgame (Month 3+): Paid rerolls for `Requiem` OK
│
├─ Is this Healer (Elizabeth) or Tank (Escanor)?
│ └─ YES → Free dailies only → Stop at `Blessing`/`Adamant` (Legendary) → Lock
│
└─ NO (Sub DPS, Flex, Farmer) → FREE DAILIES ONLY → Never pay4. Infinite Mode Tickets (1,000 Gems) — ★★☆☆☆ NICHE
When Worth It
- Leaderboard Push: Top 100 = Exclusive rewards (worth 50k+ gems)
- Event Milestones: Double reward events (2x crystals/gold)
- Speedrunning: Personal best attempts
When NOT Worth It
- Regular farming: 3 free runs/day sufficient
- Gold farming: Free runs give 90% of paid run value
- XP farming: Codes give better XP/hour
TRAP PURCHASES — Destroy Your Account
❌ Mythic Banner (10,000 Gems per 10x) — WORST VALUE IN GAME
| Metric | Legendary Banner | Mythic Banner |
|---|---|---|
| Legendary Rate | 1% | 0.5% |
| Mythic Rate | 0.1% (bonus) | 0.5% |
| Pity (Legendary) | 90 | 180 |
| Pity (Mythic) | N/A | 180 |
| Cost per Legendary | ~10,000 gems | ~20,000 gems |
| Cost per Mythic | ~100,000+ gems | ~180,000 gems |
Math: You get 2x fewer Legendaries for same price. Mythic rate only 5x higher but pity 2x longer. Net negative EV.
Exception: NEVER. Even whales should pull Legendary Banner for Legendary fodder + Mythic chance.
❌ Gold Purchases (1,000 Gems = 100,000 Gold) — TERRIBLE VALUE
| Purchase | Gems | Gold | Gold/Gem | Farm Equivalent |
|---|---|---|---|---|
| Shop Pack 1 | 100 | 10,000 | 100 | 10 sec Infinite |
| Shop Pack 2 | 500 | 50,000 | 100 | 50 sec Infinite |
| Shop Pack 3 | 1,000 | 100,000 | 100 | 100 sec Infinite |
| Infinite City (Wave 500) | 0 | 1,000,000+ | ∞ | 2 min AFK |
Never buy gold. Infinite City gives 10x better rate for free.
❌ XP Boosts (500 Gems = 2x XP 30min) — BAD VALUE
- Codes give free 2x XP boosts (multiple per week)
- Infinite Mode gives 500k-1M XP/run for free
- Weekend Events give 2x XP globally
- Only use: If you have 0 codes, 0 event, need Level 5000 today for evolution
❌ Cosmetics (Skins, Emotes, Titles) — ZERO GAMEPLAY VALUE
- No stat bonuses
- No progression impact
- Pure vanity
- Exception: If you have 1M+ gems and everything maxed (whale territory)
❌ Stamina/Energy Refills — DOESN’T EXIST
- Anime Defenders has NO energy system
- Infinite Mode = Unlimited runs
- Raids = Key-based (3 free/week + coins)
- Any “energy refill” is a scam/confusion with other games
F2P vs Whale Strategies
F2P Strategy (0$ Spent)
| Phase | Gem Allocation | Monthly Target |
|---|---|---|
| Month 1 | 80% Legendary Banner, 15% Slots, 5% Rerolls | Main DPS + Healer + Tank |
| Month 2 | 50% Legendary Banner, 30% Slots, 20% Rerolls | Flex units + Divine locks |
| Month 3+ | 20% Legendary Banner, 30% Slots, 50% Rerolls | Requiem push + Collection |
F2P Golden Rules:
- Only Legendary Banner — Mythic Banner is a scam
- Slots before pulls — Can’t use units without slots
- Free rerolls daily — 3/day = 90/month = 3-4 Legendary traits/year free
- Save 50k gems — Next limited banner / emergency
- Codes = Income — Redeem daily, it’s your salary
Whale Strategy ($100+/month)
| Addition to F2P | Allocation |
|---|---|
| Paid Rerolls | Main DPS Requiem push (10k-20k gems) |
| Extra Slots | 250+ for collection/alts |
| Event Packs | Only if >2x value (rare) |
| Mythic Banner | Still no — Legendary Banner better EV |
Whale Truth: Money only speeds up trait rerolls and collection. Core progression (Main DPS + Healer + Tank) is time-gated by codes/raids, not gems.

Advanced: Gem Value of Time
Hourly Gem Equivalent
| Activity | Gems/Hour | Notes |
|---|---|---|
| Infinite City (Wave 500) | 50,000+ | Gold → Unit Levels → Progress |
| Raid Clear (King Cursed) | 20,000 | Crystals + Coins + Ticket |
| Code Redemption (Daily) | 100,000 | 30 sec for 30k gems |
| Legendary Banner Pull | N/A | Converts gems → Progress |
| Trait Reroll (Paid) | N/A | Converts gems → Power |
Insight: Playing the game (Infinite/Raids) generates more “gem value” than buying gems. Time invested > Money spent.
FAQ
Q: I have 100k gems. Should I do 10x Legendary Banner 10 times? A: Only if you lack core units. If you have Main DPS + Healer + Tank + 2 Flex, save for next banner.
Q: When does the Legendary Banner rotate?
A: Monthly (usually 1st of month). New units added, old stay. Check Discord #announcements.
Q: Should I pull on Event Banner? A: Only if featured unit is S-Tier (check tier list). Event Banner usually has same rates as Legendary but limited pool.
Q: How many Unit Slots do I really need? A: 150 = 3 full teams (12) + Code units (20) + Fodder (50) + Collection (40) + Buffer (28). 200 for comfort.
Q: Can I get a refund on gem purchases? A: Roblox policy: No refunds on virtual currency. Double-check before confirm.
Q: Is there a “best time” to pull? A: No pity carryover between banners. Pull when you need units. New unit release = slightly better (added to pool).
Q: How do I track my gem spending? A: Spreadsheet or notepad. Track every 10k spent. Awareness prevents whale traps.
Q: What if I accidentally bought Mythic Banner? A: Lesson learned. Don’t do it again. The units you got are keepers, but the gem efficiency was -50%.
