Refresh rankings after Roblox description edits, gamepass changes, update notes, or source-backed value data.
This tier list ranks the decisions that affect a climb: warmth when freezing stops progress, backpack space when capacity ends runs, pickaxe power when mining is slow, and paid boosts as optional caveats.
Refresh rankings after Roblox description edits, gamepass changes, update notes, or source-backed value data.
Rank by the problem ending the run: freezing, full backpack, slow mining, weak sell timing, or paid boost ownership.
The verified loop is climbing, mining, selling, and upgrading gear, so this page ranks those decisions instead of unsupported meta claims.
Use this as a decision order, not a promise that one upgrade is always best. The right priority changes when your run blocker changes.
Cold risk
The official page warns the top is cold. If runs end because you freeze, warmth becomes the first upgrade priority.
Source check: Official Roblox description confirms cold risk and warmth upgrades.
Cash route
A bigger carry limit lets a climb last longer before selling crystals. x4 CARRY KG is source-backed as a paid option.
Source check: Official description confirms backpack upgrades; game-pass API confirms x4 CARRY KG.
Mining speed
Pickaxe power matters when mining feels slow. Diamond Pickaxe is source-backed as a paid high-power option.
Source check: Official description confirms pickaxe upgrades; game-pass API confirms Diamond Pickaxe stats.
Warmth, pickaxe, and backpack upgrades are source-backed by the official Roblox description.
Gamepasses can change the bottleneck, but they should stay separate from base-game advice.
Exact crystal values, upgrade prices, and warmth thresholds remain needs-check until verified.
The planner helps choose the next upgrade based on your current run blocker. Wiki pages explain paid boosts and crystal data gaps.
