💎 Never Buy Regular Diamond Packs
The #1 spending mistake in this game: Buying diamonds directly from the diamond store. There is zero value in doing this. Every single dollar you spend on a regular diamond pack is money left on the table.
The game sells diamonds at a flat rate of roughly 500 diamonds per $1 across all pack sizes — there's no bulk discount. But here's what most players miss: the game also sells dozens of themed packs at the exact same price point that include the same number of diamonds PLUS significant bonus items.
Same Price, Massively Different Value
Let's compare what $4.99 gets you:
💎 Regular Diamond Pack
- • 2,500 Diamonds
- • Nothing else.
🎁 Scarlett's Gift
- ✓ 2,500 Diamonds
- ✓ 10 Scarlett Fragments
- ✓ 5 Legendary Deployment Skill Books
- ✓ 5 Legendary Patrol Skill Books
- ✓ 25,000 Hero EXP
- ✓ 2,500 VIP Points
🏛️ Powerful PD Pack
- ✓ 2,500 Diamonds
- ✓ 18× 1-Hour Construction Speedups
- ✓ 200× 5-Min Construction Speedups
- ✓ 2,500 VIP Points
- ✓ 5M Cash + 5M Ammo
- ✓ 1M Electricity + 250K Gas
The Rule
If you want diamonds, buy a themed pack that includes the same number of diamonds. You pay the exact same price and walk away with everything the diamond pack would have given you, plus a pile of bonus materials. There is literally no scenario where buying the regular diamond pack is the right move. Browse the store's rotating packs and events before you spend — there's almost always a better deal available at every price point.
This applies at every price tier. The $0.99, $4.99, $9.99, $19.99, and $49.99 packs all have themed alternatives that include the same diamond count plus bonuses. The game doesn't give you a bulk discount for bigger diamond packs either — it's a flat ~500 diamonds per dollar regardless of pack size — so there's no reason to "buy big" on diamonds alone.
No Themed Pack At Your Price Tier? Split It.
Say you want a big diamond top-up — the kind you'd normally cover with the 10,000-diamond / $19.99 regular pack — but the rotating store has no themed offer at the $19.99 tier right now. Don't buy the regular pack. Instead, buy multiple smaller themed packs that add up to the same spend. For example, 4× $4.99 themed packs = $19.96, which gets you the same ~10,000 diamonds plus four pack's worth of bonus speedups, fragments, skill books, resources, and VIP points. The diamond-per-dollar rate is identical at every tier, so splitting your spend across themed packs is pure upside.
⚠️ First-Purchase Double Diamonds Is Still A Trap
The game offers double diamonds on your first purchase of each pack tier, and it's tempting to think this finally makes the regular diamond pack worth buying. It doesn't. Yes, the doubled $4.99 regular pack gives you 5,000 diamonds vs the themed pack's 2,500 — an extra 2,500 diamonds (~$5 of value). But the themed pack's bonuses — speedups, hero fragments, skill books, resources, VIP points — are typically worth well more than that extra $5.
💉 Vault Tranquilizer Syringes
Before each vault run, alliance members should donate their Tranquilizer Syringes to the Vault Trap. Each level of the trap increases your entire alliance's attack against the vault boss (Master of Heists), stacking up to +25% at Level 5. That's a massive damage multiplier applied to every single rally.
| Trap Level | Attack Bonus |
|---|---|
| Level 1 | +5.0% |
| Level 2 | +10.0% |
| Level 3 | +15.0% |
| Level 4 | +20.0% |
| Level 5 | +25.0% |
Only Source
Syringes can ONLY be obtained from daily intel tasks. There is no other source.
Only Use
They have no other use in the game. If you're sitting on them, you're wasting them.
Bonus Coins
Every donation earns you 200 Alliance Coins for the Alliance Store. Zero reason not to donate.
The trap requires 300 donations per level (alliance-wide), so every contribution matters. Check your inventory and donate before the vault opens.
TL;DR — The Quick Hits
- 1. Never buy regular diamond packs. Themed packs at the same price give the same diamonds plus free bonus items.
- 5. Donate Tranquilizer Syringes before every vault run. They have no other use and give +25% attack to the whole alliance at max level.
