Cost for desired stats
Enter your base HP and ascension plan.
Calculate experience and hair batches for stat ascensions while accounting for the HP reset between batches.
One stat ascension is modeled as three consecutive HP purchases: current HP × 500, then (HP + 50) × 500, then (HP + 100) × 500. HP returns to the entered base after each full hair batch.
This reproduces the reviewed community batching model. It does not consume HP; HP is the price basis.
