Published 22 Jun 2026
This is your complete Honor of Kings Grand Venture event guide — everything you need to win the Season 15 treasure economy. The Grand Venture launched June 17, 2026 with the HoK Plus 2.0 update: you dig up treasures, gamble them in a trade-up machine, and the jackpot is a free 1,688-Token Voucher you cash straight into any skin.
Sounds simple. It isn’t. The trade-up system is rigged with RNG traps that feel like progress while quietly torching your Treasure Coins. Here’s the whole thing in five minutes — and the one trap that eats whales alive.

How The Grand Venture works
Your Spriteling’s passive “Dig It” skill triggers up to 10× per match, handing you Gold, EXP, and shields — plus a small chance to unearth a treasure. Treasures are the whole economy:
1 · Dig
Play matches; “Dig It” unearths treasures across five tiers.
2 · Decide
Per treasure: Sell it for coins, or feed it into a 3-for-1 trade-up.
3 · Redeem
Spend Treasure Coins on free skins — and the 1,688 Voucher.
Selling is instant: open your inventory, tap a treasure, hit Sell, bank the coins. The entire game is knowing when to sell and when to gamble.
The official “Dig It” breakdown — a passive skill, up to 10 digs per match.
The five treasure tiers
Treasures drop in five tiers, and each tier has a huge internal value spread — two “A-tier” treasures can be worth wildly different amounts. Those midpoints drive every calculation below.
5k – 10k
avg 7.5k
28k – 108k
avg 68k
180k – 880k
avg 530k
1.4M – 3.4M
avg 2.4M
4.4M – 12M
avg 8.2M
Trade up or sell? The only decision that matters
Get this binary right and everything else is detail:
▲ Trade up
Cheap stuff — D & low-C. Combining three of them launches their value up to 5.5×. Always trade these.
▼ Sell
Your best — high-A & all S. Trading them only loses value. Hit Sell and bank guaranteed millions.
The trade-up matrix (where the traps hide)
Feed in 3 treasures, get 1 back. The grade you receive is decided entirely by the combined Treasure Coin value of your inputs. Expected Value (EV) below uses tier midpoints — green = winners, red = wealth-destroying traps:
| Combined input | S | A | B | C | Avg out | Verdict |
|---|---|---|---|---|---|---|
| Under 40k | — | — | — | 100% | 68k | Excellent ROI |
| 40k – 150k | — | — | 34% | 66% | 225k | Efficiency King |
| 150k – 300k | — | — | 80% | 20% | 438k | Great Value |
| 300k – 500k | — | — | 100% | — | 530k | Safe but Slow |
| 500k – 950k | — | 30% | 70% | — | 1,091k | Danger Zone |
| 950k – 1,300k | — | 56% | 44% | — | 1,577k | Smart Gamble |
| 1,300k – 2,300k | — | 100% | — | — | 2,400k | Profit Floor |
| 2,300k – 4,500k | 5% | 95% | — | — | 2,690k | Value Black Hole |
| 4,500k – 6,500k | 10% | 90% | — | — | 2,980k | Severe Value Loss |
| Over 6,500k | 18% | 82% | — | — | 3,444k | The Ultimate Trap |
See the cliff? EV climbs all the way to the 1,300k–2,300k bracket, then every higher bracket pays back less than you put in. Those red rows are bait.
The cheat sheet
▸ ▾
Advanced plays — micro-optimization & hidden traps
The “A-Tier Cleanse” reroll. Holding a baseline A-Tier (1,400k) you don’t love? Pair it with two 5k D-tier feeders (1,410k total) to land in the 1,300k–2,300k bracket — a 100% safe reroll into a fresh 2.4M A-Tier, averaging +990k profit with zero downgrade risk.
The “Bridge-to-A” leap. Two high B-tiers (~900k) alone sit in the brutal 70%-fail zone. Add one cheap 101k C-tier to reach ~951k and jump into the 950k–1,300k bracket for a 56% A-Tier flip. A 101k investment swaps a coinflip-loss for a coinflip-win.
High B-Tier dilution trap. A standalone B-tier worth >800k should never be traded. In the 1M bracket you take a 44% coinflip to drop an 800k asset to a 530k average. Sell it.
The “over-baking” rule. Profit lives on the floor of a bracket. Dropping 290k into the 150k–300k zone barely beats selling — the EV was priced for a 151k input, not 290k. Drifting toward a ceiling? Liquidate or rebuild the stack.
Play the floors, never the ceilings, ignore the S-Tier bait — and that pile of Spriteling junk turns into the 1,688 Token Voucher and a free skin to show for it.
Grand Venture FAQ
How do you get the 1,688 Token Voucher?
Bank enough Treasure Coins (by selling treasures from your inventory) and redeem the 1,688 Token Voucher in the event shop — then spend it on any skin, with no minimum top-up required. Trade up your cheap treasures and sell your best ones to pile up coins fastest.
Should you sell or trade up treasures?
Trade up cheap treasures (D and low-C tiers) — combining three of them multiplies their value. Sell your best treasures (high-A and all S tiers) straight from your inventory, because trading them up only loses value on average.
What’s the best trade-up in the Grand Venture?
The 1,300k–2,300k combined-input bracket: it’s a guaranteed A-tier (2.4M average) for the lowest qualifying input. For cheap items, the 40k–150k bracket is the highest-percentage growth in the event.
Can you sell treasures in the Grand Venture?
Yes — open your inventory, tap a treasure, and hit Sell to instantly convert it to Treasure Coins. There’s no marketplace step; selling is one tap.
