Task Bar Hero Cube Guide | Stat Roll Odds & Costs
This Task Bar Hero cube guide covers how cube washing actually works: every roll is independent, so the odds of hitting a legendary affix are fixed by the affix pool at that item's rarity, not by how many times you have already rolled. Work out the expected gold cost of a target affix before you start, decide in advance when to stop rolling, and compare that cost against simply buying the item from the Steam Community Market.
1. The Mathematics of Cube Washing: Geometric Distribution
Washing stats on equipment behaves as a sequence of independent Bernoulli trials. The number of rolls needed to succeed follows a Geometric Distribution. Each single roll has a fixed probability (e.g., 3% for a Legendary quality stat, 12% for an Epic quality stat). The expected value of washes needed is 1/p. For example, getting at least 1 Legendary slot has a p of 3% per slot, meaning you should prepare for approximately 33-35 rolls on average.
2. Rarity Weights & Optimal Washing Presets
• Legendary Stats (3% probability): Amber colored, gives the highest bonuses like +20% Attack or +10% Crit Rate. This is the endgame gold standard. • Epic Stats (12% probability): Purple colored, highly cost-effective for mid-game players. • Presets: For casual progression, aim for 'At least 3 Epic+' to boost your clear times without burning all your gold. For endgame optimization, prepare a massive budget (~185 million Gold and 37,000 Cubes) to lock in '4 Legendary' stats.
3. Class-Specific Best Stats Priorities
• Tank (Knight): Prioritize Armor, Max HP, and Cooldown Reduction (CDR) to maximize defensive skill uptimes. • DPS (Ranger, Slayer): Prioritize Attack Damage, Crit Rate, and Crit Damage. Slayer scaling with high Crit Damage is particularly devastating. • Mage (Sorcerer): Focus on Attack Damage and Cast Speed to clean waves instantly.
4. When Should You Stop Rolling?
The decision to keep rolling is an expected-value question, not a gut feeling. Every roll is independent, so a run of failures does not make the next roll more likely to succeed — the expected number of attempts for a target affix is fixed by the size of the affix pool at that item's rarity, and it does not shrink because you have been unlucky. What does change as you keep rolling is how much gold you have already sunk into the item. That sunk cost is irrelevant to whether the next roll is worth it. The only question that matters is whether the expected gold to reach the target is less than the value of the upgrade. If a weapon needs an expected 8 million gold to hit its target affix, and an equivalent weapon of the next rarity tier is listed at 3 million on the Steam Community Market, the correct move is to buy rather than roll. Re-check that comparison whenever the market price moves, because a change in price changes which answer is right. A practical stopping rule: set the maximum you are willing to spend before you start, and stop when you reach it, whether or not you have hit the target. Continuing past a limit because of what you have already spent is how cube sessions turn into drained accounts with nothing to show for them.
5. Cube Budget Planning by Progression Stage
Where cube budget should go changes as an account progresses. Early on, the cheapest power available is a small number of rolls on the low-level item that is holding back your clear speed: the absolute gold cost is tiny and the immediate gain is large. Mid-game, budget should concentrate on the slot your main damage dealer uses, because a better weapon multiplies every other stat you own. Spreading rolls evenly across six slots produces six mediocre items; concentrating them produces one item that carries the team. Late-game, rolling becomes a comparison against the market rather than a purely in-game decision. High-rarity items are tradeable, so the question shifts from "how many rolls" to "roll or buy". A useful rule is to cap cube spending per session at a fixed fraction of your hourly farming income. If a target needs more than that cap, treat it as a multi-session goal and keep farming in between rather than draining the balance in one sitting. A drained balance also means no gold left for enhancement levels — and enhancement is a guaranteed gain, while a roll is a probabilistic one. Guaranteed gains first, gambles second.
