TBH: Task Bar Hero Cube Guide

Cube's 8 Functions (and When They Matter)

The Hero-dric Cube is not one system. It is eight, and they do very different things. A player who opens the Cube menu and sees Synthesis, Alchemy, Crafting, Decoration, Engraving, Inscription, Extraction, and Offering all at once often spends materials on the wrong operation. The result: slow Cube levels, weak gear, and a stalled account.

The fix is simple: ignore 5 of the 8 functions until mid-game. Focus on Synthesis and Crafting. Leave Decoration, Engraving, Inscription, Extraction, and Offering for when you have materials to spare and gear worth enhancing.

Cube Leveling Route

Cube levelling is simple when you know the milestones. Before Cube 15, your only job is to feed Synthesis with Basic Shards. At ~4,500 XP per hour, you reach Cube 15 in about 11 hours of active play. That is where the game changes: XP multipliers kick in retroactively for high-tier materials, so every Stellar Ruby and rare gem you saved starts paying back.

If you burned your rare materials before 15, you lose about 40 hours of mid-game grind. That is not an exaggeration — the math is straightforward. A saved Stellar Ruby used after 15 generates thousands more XP than the same Ruby used at level 5.

Operation Guide: What Each Function Is Actually For

Synthesis — Your Main XP Engine

Synthesis combines materials into permanent upgrade cores. The simplest recipe: 10x Basic Shard = Tier 1 Core = 50 XP (5 XP per material). This is the most efficient XP source in the game. Keep at least 100 basic gems in your inventory at all times so the offline crafting queue does not stall when it runs out of material. Synthesis stays relevant even after Cube 15.

Crafting — Targeted Gear Upgrades

Crafting uses base materials along a known rarity ladder: wood, stone, leather → copper nuggets → bronze ingots → iron ingots → silver ingots → gold ingots → stardust ingots / void iron → bloodstone / thunderstone. Each tier unlocks stronger equipment. Craft when you know exactly what the active hero needs. Do not craft for bench heroes.

Alchemy — Delay Until 20

Alchemy converts materials into gold. It gives 3 XP per material vs Synthesis at 5 XP. That 40% gap compounds over hundreds of materials. At Cube 20, start with a 80/20 split (Synthesis/ Alchemy). Never go above 20% Alchemy — the XP loss is not worth the gold income at early levels.

Decoration, Engraving, Inscription — Mid-to-Late Game

Decoration: 36 gem types (ruby, sapphire, topaz, emerald, amethyst) go into gear sockets for stat bonuses. Engraving: 33 monster materials (goblin hide, skeleton bone, slime jelly) inscribe rune-like effects. Inscription: 10 scroll tiers from Common to Cosmic apply special affixes. None of these matter before you have good gear to socket. Do not rush them.

Common Cube Mistakes

Cube mistakes usually come from opening every menu and trying everything at once. The player sees materials piling up, a craft option, a synthesis path, and an alchemy recipe — and wants to turn them into progress immediately. Sometimes that works. Usually it consumes the exact input needed for the next real upgrade.
