Expertise

A permanent Blacksmith Power-Up. Each rank increases XP (experience) gain rate, reducing the time needed to level up cards and reach evolution thresholds.

• High priority in multi-evolution builds (Lama-style)
• Useful for quickly opening gem slots by reaching weapon max level
• Some investment benefits all builds

• Multi-evolution build (Lama): Evolution speed determines run success — Growth is essential
• Early-acceleration builds: Reach weapon max level (10) fast for gem slot unlocks
• Long-run builds: Cumulative XP advantage unlocks more options in late waves

XP rate increases incrementally per rank. Even early ranks provide noticeable impact.

Direct damage and survivability improvements come from other Power-Ups. Growth is infrastructure investment — less visible but provides long-term leverage throughout the run.
