Core Fragments

DIRECT ANSWER

Core Fragments: current answer

Core Fragment guidance and encounter rewards changed after launch: AG-25 improves unlock prompts and increases Core Fragment chests in Infested Nest. These notes support a dated acquisition history, not an exact farming-rate table.

Quick facts

  • AG-12 adjusted Core Fragment pod collision so spawning pods do not obstruct the Leader.
  • AG-25 adds more Core Fragment chests to Infested Nest and improves when unlock prompts appear.
  • AG-25 fixes banned Cores appearing in Core Fragment Pods, but explicitly retains an early-game exception when every available set-starting Core is banned: the reserved first slot may still show one.

Practical workflow — editorial guidance

If a pod seems to ignore a ban, record whether it is the reserved first slot and whether every available set starter is banned before calling it a new regression.

Separate a missing unlock notification from a missing reward; record the encounter result and the prompt timing independently.

When comparing Infested Nest rewards, keep the build and encounter conditions with the observation rather than assuming a fixed return from one run.

Chest counts, drop percentages, inventory limits and fragment-to-Core conversion rules are not comprehensively specified by these sources.
