Residual Knowledge
Residual Knowledge is a Shatter path perk for pickaxe prestige. It makes blocks you never personally touched still pay out XP, and nudges up the Ancient Energy they give.
At a glance

| Slots | Any perk slot (P1, P5, P10) |
| Affects | Blocks broken by Shatter that you had made no mining progress on |
How it works
Mining XP is normally paid in proportion to how far you actually chewed through a block. A Shatter blast levels a whole cube around you, and almost every block in that cube is one you never swung at — so by default those blocks pay no XP at all, only ore.
Residual Knowledge gives them a small XP payout anyway. The rate is half your rolled value, measured against what a fully hand-mined block would have given:
| Roll | XP per untouched shattered block |
|---|---|
| 3% | 1.5% of a hand-mined block |
| 4% | 2% |
| 5% | 2.5% |
| 6% | 3% |
Those blocks also pay slightly more energy — their energy rate is multiplied by 1 plus that same fraction, so a 6% roll is about 3% more energy on shattered blocks.
Notes
- The numbers look tiny per block, and that is the point: a single Shatter can clear hundreds of blocks, so a fraction of a percent each adds up to real throughput.
- It does not apply to Tartarus (P11) discharges. Those pay their own per-perk XP, energy and ore blend instead.
- Blocks you had made progress on already pay by progress, and are unaffected.
- XP that lands above your current level cap is discarded, so the perk does nothing while you are capped out.
