Shard Milestone Buy Order

While growing shard income, spend most shards on milestones that raise shards or Cells. Near the end of a run, switch to MP milestones. Rules:

1. Unlock new milestones early. Cheap levels in the first few open stronger ones.
2. Early: Alpha (Cells), Aquarius (MP and MK4), Libra (MK1 to MK3), Modifying (MP, and a tick cut at level 75), Flowering (Shards).
3. Mid: Morphing (big Cells boosts at levels 1, 25 and 75), Extracting (shards and MP), Seeding, Duality (Cells and MP).
4. Torn is a very strong MP and shard milestone (level 25 and up) once you reach it.
5. Late: Machining, Studying and Layering are strong multi-effect milestones. Fabricating and Wonderous give large all-generator and MP boosts at levels 30 and above.
6. Tick cuts (Modifying and Pathing, at level 75) cap at about 0.3 seconds each.
7. If shard income is the bottleneck, buy shard-producing levels even if they cost more than the cheapest option.
8. Spend shards before a reset. They are lost otherwise. See Before You Reset.
