Are Elite Traps always these three items?
This was one Defense restock, with New items in 3m 12s. The next timer can show different rows. The prices here match that frame only.
Traps
ELITE TRAPS uses the same Defense and Blocks tabs as the Dino Shop, with a timer. The three rows below were in stock together once. They are not a fixed shop list.
Updated

The panel title is ELITE TRAPS. The header still has New items in and a countdown. On this frame it read 3m 12s, and a hexagon button showed 5. Defense and Blocks sit underneath, the same two tabs as DINO SHOP. Defense was the open tab.
The official description tells you to place traps and turrets to defend your egg. This panel is the trap list we could read. It is still a rotating stock. A row that says x1 Stock can leave after one purchase, and the timer says the set will change.
The first row is named Tar Pit. The price is $180000, with x1 Stock under it. The description reads Thick tar. Anything crossing it crawls. The button says Legendary.
Legendary is the word on that gold-tan button. It is not printed on orange index cards. Titanosaurus can be orange and still only say DINO. Tar Pit says Legendary because it is a shop row. The price is cash, the same dollar sign as the index, just three zeros larger than Ankylosaurus.

The middle row is Spine Roller. Price $240000, x1 Stock, button Legendary. The description is A studded drum. Grinds the whole lane.
The whole lane is the useful part of that sentence. Tar Pit slows whatever crosses it. The roller says it grinds the lane, not a single target. Neither row prints a damage number. If you need DMG, SPD, and HP, that is the index, not this shop.

The bottom row is Salvage Crane. Price $300000, x1 Stock, button Legendary. The description is Rebuilds your destroyed traps mid-run. The name is Crane. A first read of the footage called it Grane. The zoomed row says Crane.
This is the only one of the three whose sentence is about repairing, not about hitting a dino. Bone Mender, on the cheaper shop, says it repairs your most damaged defences for $17500. The crane is the $300000 version aimed at destroyed traps during the run. They are different rows.

If this exact restock is up, Tar Pit is the one you can afford first, at $180000. It is also the one whose text is a slow, which matters because boss cards are already slow: Titanhorn's SPD is 3.5 and Grovebreaker's is 2.8, while early dinos sit around SPD 20. A slow on a fast early wave is the row that matches the problem you can see.
Spine Roller is the next $60000, and it is the lane clear. Salvage Crane is the last $60000, and it only pays you back if traps are actually being destroyed. Buying the crane before you own a trap to rebuild is the expensive order. None of this is a permanent tier. The timer can replace all three.
| Trap | Price | Stock | Button | What the row says |
|---|---|---|---|---|
| Tar Pit | $180000 | x1 Stock | Legendary | Thick tar. Anything crossing it crawls. |
| Spine Roller | $240000 | x1 Stock | Legendary | A studded drum. Grinds the whole lane. |
| Salvage Crane | $300000 | x1 Stock | Legendary | Rebuilds your destroyed traps mid-run. |
A dino card tells you when it unlocks, because the header says DINO - WAVE. A trap row does not. Tar Pit does not say wave 40 or wave 70. You can buy it when it is in stock and you have the cash. The wave bar on the HUD is a separate number.
Place the trap from the tools you were given, then start the fight with the green Fight button. While the wave is running that button says Stop. The trap row itself does not show a hotbar slot number, so this page does not invent one.

No. Legendary is the word on the trap button. Orange is the header color on Diplodocus, Dimorphodon, and Titanosaurus, and those cards say DINO, not Legendary.
