#How it works

1. Pay potions, wait
   One research at a time.
2. Unlock by path
   A node opens once the nodes above it are done.
3. Tiers repeat
   Same nodes every tier, up to 5 levels. Copies add up.
4. Price = tier + level
   What the node does doesn't matter. A new tier always costs more than the last one's top level.
