C's Cube Overview

**C's Cube** is the **Unheard Shores** counterpart to C's Tower — same boss **Proliferative C**, different entry. Find the black **C-marked box** in the **forest north of Wertheimer Tower** (near Orichalcos Imaginist). The anomaly spawns a close-range block maze you must climb before the summit fight. Hunter EXP ×200, no Arc.

How to Complete

• Track **C's Cube** on the Anomagram → grassland / forest **north of Wertheimer Tower**, Unheard Shores
• Enter the Wertheimer Index zone — lighting dims as Proliferative C activates
• Approach the floating **black box with yellow C**; blocks manifest only when you stay near them
• Navigate the **box labyrinth** — footholds appear at close range, forming a vertical tower
• Climb stacked manifest blocks to the top platform where the main body waits
• Touch Proliferative C at the summit — it **rams you** to start the combat arena
• Defeat Proliferative C and **close the box** to nullify the phenomenon
• If rewards fail to trigger after victory, land a few hits on the **arena center** (stuck-state workaround shared with C's Tower)

Proliferative C — Weakness & Strategy

**Boss:** Proliferative C · **Weakness:** check the team-select weakness icon — elemental line not listed in verified commission references

• Same split mechanic as **C's Tower**: near **one-third to half HP**, Proliferative C **duplicates** and both copies attack together
• Prioritize deleting one copy with burst to reduce crossfire on the forest summit arena
• Dodge aggressively — joint slam patterns overlap during the dual phase
• Maze climb is the time sink; combat itself mirrors the Bridge Crossings tower variant

Rewards

• Hunter EXP ×200
• Annulith
• Fons
• Beetle Coins
• Anomaly Material Selection Box I
• No free Arc on this commission.
