Clear the last wall and the grotto reforms as a different stone rather than a repeat — a new creature to ink into the Ledger, a livery that's never a duplicate, and a guaranteed materials payout, all before a single card is drawn. Then three cards turn from one published table, the odds on screen the exact weights the draw uses, with a visible pity counter: go two stones without a drone part and the third is guaranteed one. Every payout — the cards, a wave's own drop, even the Titan's — is capped to a fraction of a full recipe, so a stone contributes to a top-tier build and never hands one over outright.
The daily strike cell recalibrated too, from 12 strikes down to 10, tuned so the same twenty-day cycle holds regardless — the wall still chips at the identical rate no matter which rank of mount is swinging it, on purpose. And Breach Shards changed shape: instead of a one-time grant on the very first wall, every threshold wall now rolls its own 50/50 the moment it opens, with the fifth and final wall guaranteed if the whole cycle rolled nothing. Full numbers in the guide: The Breachstone.
