When to Climb

Early Stairs (1-3)

Timing: Mid-game (Ascensions 5-10) Strategy: Complete during natural progression

Mid Stairs (4-6)

Timing: Late-game (Ascensions 10-20) Strategy: Save up specifically for these

Late Stairs (7+)

Timing: Endgame (Ascension 20+) Strategy: Major investment, plan carefully

Climbing Strategy

Efficient Approach

1. Don’t climb too early - focus on Evolution/Ascension first
2. Climb during strong runs (good weather, multipliers)
3. Complete stairs before Ascending when possible
4. Stack with other permanent bonuses

Inefficient Approach

❌ Rushing stairs at expense of Ascensions ❌ Climbing without Evolution complete ❌ Spending last money before Ascension
