Holy Grail

Lore

No one remembers who first held the Holy Grail, only that whoever carried it never went hungry for long.

Description

A cup that overflows with riches.

Complete Statistics

Ability

Increases your total passive income (from all owned businesses) by 20.0% per level.

Upgrade Scaling

The bonus below applies at every level from 1 up to this card's maximum of 6.

Duplicate Bonuses & Combining

Pulling a duplicate of Holy Grail from a pack adds a spare copy to your collection. Spend spare copies in the Cards tab to combine and raise its level — each level costs a number of copies equal to the card's current level. Reaching the maximum level of 6 from level 1 requires 15 total copies. Read the full Duplicate Cards & Combining guide for the general combine mechanics, or use the Combine All button in-game to apply every possible level-up across your whole collection at once.

Evolution

Tycoon Cards does not currently have a card evolution system — Holy Grail progresses only through the standard duplicate-combine mechanic described above. Evolution is listed as a researched feature on our Updates & Roadmap page; this page will be updated if it's ever implemented.

Fusion

There is no cross-card fusion system in Tycoon Cards today. Every card, including Holy Grail, is levelled independently using its own spare copies — you cannot combine it with a different card. Like Evolution, this is tracked as a possible future system on the Updates page.

Collection & Faction

Holy Grail belongs to the History collection — one of the thematic groupings used across the card archive. Browse every card in this collection from the main Card Guide, or see the "Related cards" section below for direct links to its closest siblings.

Businesses That Synergise

Passive-income bonuses apply a flat percentage to your total business income, so they have the largest absolute effect on whichever businesses currently produce the most money for you.

Prestige Interactions

Passive income is calculated as totalBusinessIncome × (1 + passiveBonus + globalBonus) × prestigeMultiplier — so this card's bonus is multiplied by your prestige multiplier.

Best Strategies

• Level this card up before investing heavily in your highest-tier businesses — the percentage bonus is worth more once your passive income is already large.
• Especially valuable in the mid-to-late game once you own several business tiers simultaneously.
• As a Legendary card, expect to pull duplicates mostly from Elite Vaults — plan your Elite Vault purchases around completing this card's level curve.

How to Unlock

Holy Grail is obtained by opening card packs — it cannot be purchased directly or unlocked through any other method. As a Legendary card, it appears in any pack whose odds include that rarity.

Pack Availability

See the full Card Pack Odds Guide for how these probabilities are calculated.

Event Availability

Holy Grail is not currently tied to any seasonal or limited-time event — it's available year-round through standard pack odds. Seasonal events and event-exclusive cards are listed as a planned feature on the Updates & Roadmap page.
