Upgrades define the early and mid-game Oof economy. The eight foundational upgrades each carry a base cost, an algorithmic boost yield, and a calculated ROI score. Spend order matters more than spend volume — clicking Noob Production ten times is worth more than a single Oof Multiplier at the start of a run.
Adds +0.50x baseline Noob output. Universally the first upgrade you should max. ROI 50.00, the highest in the matrix.
Adds +0.20x manual click output. Essential to bypass early-game latency before passive Noobs scale. ROI 40.00.
Adds +1.00x global multiplier to all Oof income. Becomes mathematically dominant only after a robust passive base. ROI 20.00.
Reduces Noob generation cooldown by +0.40x tick rate. Equivalent to production density over time. ROI 13.33.
Costs 10,000 Oof to unlock Layer 2 (Rune Layer). Massive immediate sink with immense long-term compounding payoff. ROI 2.00.
Amplifies the multiplicative value of all equipped Runes by +0.80x. Inefficient until you have Rare or Epic Runes to feed it. ROI 1.60.
Unlocks idle Noob buying. Detrimental to early-game velocity due to high cost, but mandatory for Endgame Layer AFK progression. ROI 1.50.
Applies +0.10x probability shift toward higher rarity Rune drops. Small but permanent improvement. ROI 0.30.
