Mart Shopping Guide — Nullscape

The Mart is Nullscape's in-run shop where you spend Sheckles on weapons, upgrades, and utility items. Smart shopping at the Mart is one of the most impactful skills you can develop — a well-invested Sheckle budget can carry an entire run, while careless spending leaves you weak and vulnerable in later floors.

How the Mart Works

The Mart appears on every floor (usually in the first or second room). When you enter, you're presented with a selection of 3–5 items that refresh each floor. Items are drawn from a pool based on your current floor and class.

Price Scaling

Mart prices increase as you progress through floors:

This means early purchases are more cost-effective than late purchases. Spending wisely in the first few floors gives you the most value per Sheckle.

Item Categories

Weapons

Weapons are your primary damage source. They range from common pistols and swords to legendary rocket launchers and energy blades.

• Price Range: 40–300 Sheckles
• Rarity: Common, Uncommon, Rare, Legendary
• Recommendation: Always have a viable weapon. If your current weapon is weak, prioritize a weapon upgrade early.

Upgrades

Upgrades modify your stats or abilities. They stack and can be combined for powerful synergies.

• Price Range: 30–250 Sheckles
• Types: Offensive, Defensive, Mobility, Utility
• Recommendation: Build toward a coherent strategy rather than buying random upgrades.

Utility Items

Utility items provide one-time or limited-use effects: health potions, shields, keys, and special consumables.

• Price Range: 15–100 Sheckles
• Recommendation: Buy health potions when low on HP. Otherwise, utility items are lower priority.

Upgrade Priority Guide

Tier 1 — Buy Immediately

These upgrades provide universal value regardless of your class or build:

1. Health upgrades — More HP means more room for mistakes
2. Movement speed — Faster movement benefits every class
3. Weapon damage — Your weapon is your primary tool

Tier 2 — Buy When Affordable

Strong situational upgrades that depend on your class and build:

4. Class-specific upgrades — Synergize with your class ability
5. Fire rate — Increases DPS without changing weapon
6. Critical hit chance — Multiplies your damage output

Tier 3 — Buy With Surplus Sheckles

Nice-to-have upgrades that are valuable but not essential:

7. Sheckle magnet — Increases Sheckle pickup range
8. Luck bonuses — Improves Mart item quality
9. Cosmetic effects — Fun but no gameplay impact

Budget Tips

The 60/30/10 Rule

Allocate your Sheckle budget roughly:

• 60% on weapons and damage upgrades
• 30% on defense and health
• 10% on utility and consumables

This ratio keeps you dangerous enough to progress while maintaining survivability.

Don't Hoard

Sheckles left unspent provide zero value. If you die with 500 Sheckles in your pocket, that's 500 Sheckles wasted. Spend aggressively on early floors when prices are lowest.

Reroll Strategically

The Mart sometimes offers a reroll option for 20–30 Sheckles. Use it when none of the current items fit your build, but don't reroll endlessly — the cost adds up.

Save for Boss Floors

Boss floors are the hardest checkpoints. Consider saving 100–150 Sheckles before a boss floor to buy emergency health potions or a last-minute damage upgrade.

Class-Specific Spending

• Charger: Invest in speed and dash upgrades first
• Bruiser: Prioritize health and damage reduction
• Spirit: Health upgrades are critical due to low base HP
• Wanted: Save for Bounty Shop access at Tier 3

Advanced Tips

• Price checking: Hover over items to see their sell price. If you buy an item and find a better one next floor, you can sell the old one for a partial refund.
• Stacking: Two copies of the same upgrade often provide a stronger effect than two different upgrades. Check stacking rules before diversifying.
• Floor-dependent items: Some items are only useful on specific floor types. Don't buy water-breathing upgrades on a fire-themed floor.
