Money = Luck?
Description
Money = Luck? turns your coin balance into Luck through a repeating seven-coin cycle. The effect rises from negative Luck to a positive peak at each positive multiple of seven, so picking up or spending coins can change your run. Isaac's glasses show the current effect: red for negative, gray for zero, and green for positive Luck.
A seven-coin fortune cycle
Ordinary cycles can reach +2.3 Luck. Some balances have special results: 13 coins give -1.3 Luck, 21 give +1.5, 77 give +3, and 99 give -1.5. Deep Pockets extends the cycle to 999 coins, with additional special balances.
Money Clip and Rose-Tinted Glasses
Money Clip can hold a positive multiple of seven by leaving later coin pickups on the floor until you spend. A golden Money Clip or Mom's Box stops larger pickups at the next reachable lucky balance and returns the excess as ordinary change.
Rose-Tinted Glasses, found in Shops, reverse how visible Luck affects the chance of receiving a bonus penny after a paid Shop purchase. They do not change visible Luck itself.
More ways to use your Luck
Paid Shop purchases can leave an ordinary penny on the floor. Lucky Penny can preserve a lucky peak you crossed, Lucky Foot limits negative Luck from the item, and Keeper's Sack can grant an extra stat increase after a qualifying collectible purchase. The mod also supports External Item Descriptions and an in-game information display.
