+1 Upgrade Per Kill upgrade ladder: Leather to MAXED
The ladder in +1 Upgrade Per Kill has eight tiers: Leather, Copper, Iron, Full Diamond, Ruby, Shadow, Prism and MAXED. Every kill moves your gear one step up; every death sends you back to zero unless you use a Gear Saver to keep your armor.
The eight tiers
| Order | Tier |
|---|---|
| 1 | Leather |
| 2 | Copper |
| 3 | Iron |
| 4 | Full Diamond |
| 5 | Ruby |
| 6 | Shadow |
| 7 | Prism |
| 8 | MAXED |
The developer lists the tiers in this order. How many single upgrades sit inside each tier is not published; the game's "one step per kill" wording refers to gear steps, which may be finer than these eight names.
What a death does
A death resets your upgrade to zero. That is the core risk of the game: a long streak is valuable and fragile at the same time.
Gear Saver
The listing says that if you die at a high upgrade, a Gear Saver lets you keep your armor. How you get Gear Savers and whether they cost Robux is not stated on the listing.
Hunting high-upgrade players
Killing a high-upgrade player gives bonus XP, according to the developer. The official thumbnail above shows that contrast: low-tier leather facing top-tier gear.
