Caves and counterplay
The left shortcut first appears in wave 5 and repeats in wave 6. Its separate warm torch glow warns for four simulation seconds before the first emergence. Enemies retain their health and status effects underground, where they cannot be attacked.
Cover the shared final road and watch the left mouth. Later waves gradually increase shortcut pressure.

Development status
The approved v4 map and separate glow are integrated locally. The roughly 10% difficulty-increase target is not yet validated; automated results vary by strategy and novice reaction fairness needs further playtesting.
Frost Troll Chieftain packs are staged for waves 8, 10 and 12, replacing existing budgets. They remain disabled while diagonal animations await correction.
