What is the single best object?
There is no single best. Metal Blockade is the highest confirmed wall health; craft and Galaxy weapons carry damage. Placement limit decides how many of each you can field.
Late game
Placement limit, craft materials, and a short list of objects with confirmed late-game stats.

Roll for materials, craft for specific weapons and mutations, upgrade the pieces that survive high waves, and raise placement limit so the base can field more of them.
Wave clear still pays offline income. A base that dies at wave 400 earns less than one that holds 700+ even if the latter looks less optimized in a short session.
These readings come from index cards in high-wave footage. Use them as anchors, not as a full tier list — many objects still have empty stat fields on this site.
| Object | Rarity | Level | Health | DPS |
|---|---|---|---|---|
| Metal Blockade | Mythic | 1 | 25,000 | — |
| Rusty Spikes | Legendary | 1 | 8,250 | 350/s |
| Spike Shooter | Mythic | 6 | 815 | 124/s |

Keep the tier-up Legendary craft running whenever you have Refined and Epic stacks. Layer relic recipes when you have the named materials: Heavy Harpoon, Arrow Turret, Reinforced Cannon, Deep fryer, Wizard Tower.
Reinforced Cannon is gated on Shiny Basic Cannons. Wizard Tower is gated on Witch Brew. Plan bank slots for those materials before you need the craft.

Late accounts stack skill luck, index luck, group rewards, shop boosts and clovers. One endgame reading showed 1,749× luck. The odds calculator on this site deliberately ignores luck so numbers stay a worst case.
Claim index rewards every session. A pending claim is free luck left on the table.
Fifteen of twenty-one crafting recipes, boss drop tables, and most object stat cards. Empty fields mean not observed — not zero.
When the Tsunami event weapons are captured on video with readable cards, they will land in the item database with sources like everything else.

No. Coins are finite relative to the level-64 cap. Focus upgrades on pieces that stay in the final layout — craft Legendaries and high-DPS weapons first.
