Full House is a tracking problem before it is a combat problem.

Short Answer

Do not treat Full House as “defeat every obvious creature.” Treat it as a completion checklist that may require standard creatures, evolution variants, boss entries, and boss summons. The safest approach is to track the archive by category and revisit any entry type that can be hidden behind a specific run state.

Checklist Buckets

• Standard creatures and ordinary enemies.
• Evolution variants or alternate creature layers.
• Boss families and their visible variants.
• Boss summons, minions, or adds that may not look like separate completion targets at first.
• Shiny or special variants if they are tracked separately in your current build.

Why Players Miss This Achievement

Players usually remember bosses and large creatures. They forget summons, small enemies, variants, or one-off spawned units. If the game records a creature separately, defeating the boss may not be enough to cover everything around that fight.

Safer Completion Habits

Use Bestiary pages as a running checklist, not just a reading page. When a boss summons minions, do not assume the summon is automatically covered. When you see a variant with a different name or portrait, treat it as a separate candidate until proven otherwise.

What We Still Cannot Confirm

Exact scan rules can change the route dramatically. The safest public-facing wording is to say that Full House should include all documented creature categories and that boss summons are a likely miss point, not to claim a final verified scan order yet.
