• Type: Action
• Cost: 4
• Effect: Gain a card costing up to $4. Until the end of this turn, cards in the Supply cost $1 less.

Renaissance's "cost-reducing Workshop." Cost 4 gains a card up to $4, and reduces all Supply cost by $1 for the rest of the turn — stacks with multiple Inventors.

Biggest strength: stacking cost reductions. 3 Inventors = -$3, allowing $5 Provinces in the same turn (purchased, not gained, since Inventor is gain-only ≤$4).

Overall A tier. Engine core, especially strong on Potion-less boards.

Early: 4-coin top contender vs Workshop / Silver / Witch.

Mid: Chain Inventors to expand deck. Each gains a ≤$4 card.

Late: 3-4 Inventors fired drops Province cost dramatically.

Stacking:

1. Inventor 1: -$1 (Province $7, Gold $5).
2. Inventor 2: -$2 (Province $6, Gold $4).
3. Inventor 3: -$3 (Province $5, Gold $3).

$5 Provinces are decisive late game. Inventor itself can only gain ≤$4 cards; Provinces still require buy phase.

Inventor + Inventor: Stacked -$2, Province $6.

Inventor + Cargo Ship: Stash gained card.

Inventor + City Gates: +1 hand size raises hit rate.

Inventor + Bridge: Stacked cost reduction.

Inventor + Witch: Gain Witch ($5→$4).

Inventor + Throne Room: TR + Inventor = 2 gains + -$2.

• Multiple Inventors: Cumulative cost-down.
• Cargo Ship: Stash gained.
• Bridge: Stacked cost cuts.
• City Gates Project: +1 hand.
• Throne Room: Doubled.
• Witch / Curser: $5→$4 gain.
• Workshop / Remodel: Gain chains.

• Pure Big Money: No Inventor stacking.
• Quick-finish: No time to chain.
• Action-light: Terminal collision.
• No targets ≤$5: Limited gain options.

Order matters: each Inventor reduces cost AFTER its own gain. Save the highest-value gain for last after stacked reductions.

Province turn: 3 Inventors → Province $5; buy after Inventor plays.

Note: cost reduction applies to Supply only — set-aside / hand-card costs unchanged.

Avoid terminal collision: Inventor is terminal; pair with Villages or Acting Troupe (Villagers).
