How to Tame a Therizinosaurus in ARK

 

    The Therizinosaur — officially Therizinosaurus multiensis, whose name means "Scythe Lizard" — is also known in-game as "Therizinosaurus," "Therizino," "Theri," or the nickname "Tickle Chicken." It's a Knockout (KO) tame: territorial, herbivorous, and armed with claws that can shred a base wall or a rider. ark.wiki.gg flags that "the Therizinosaur will receive a TLC in ARK: Survival Ascended September 30th 2026," so if you're taming one now, expect changes soon after. This guide sticks to what the wiki's current page documents: the taming method, food/quantity/time figures across taming levels 1–150, base stats and growth, and the breeding timeline — with an explicit "undocumented" flag anywhere the source doesn't give a number.

 

Knockout Taming and Torpor Decay

 

    The infobox is explicit: Taming Method is Knockout, and Torpor Immune is No. The wiki's K.O. strategy section warns "the biggest difficulty in taming a Therizinosaurus is the sheer power for which survivors crave them," and it "can effortlessly knock out the rider" if caught within range. Quoted approach: find "a tall rock or small cliff to attack from," since it "can cross a lot of difficult terrain," and bring "a fast-moving mount, preferably Procoptodon, Beelzebufo, or Utahraptor to evade attacks." Alternatively, "a 2x2x2 trap will allow for an easy knockout." Trapping tools listed elsewhere on the page: Chain Bola, Large Bear Trap, Plant Species Y Trap, Net Projectile.

 

    Once down, torpor drains fast — faster at higher wild levels. Torpidity-depletion rate and time-to-empty: Level 1 — 2.84/s (00:05:26); Level 30 — 4.71/s (00:08:58); Level 60 — 6.15/s (00:11:23); Level 90 — 7.43/s (00:13:09); Level 120 — 8.64/s (00:14:32); Level 150 — 9.78/s (00:15:40). Arithmetic: 9.78 ÷ 2.84 ≈ 3.44, so a Level 150's torpor empties roughly three and a half times faster than a Level 1's — hence carrying "at least 100 biotoxin or a few hundred narcotics," or using "a Medical Stand" to keep pace.

 

    The per-level table also carries a bare "KO" figure list at each level, but the source attaches no row labels or weapon names (Bow, Crossbow, dart) to those numbers the way the Rex page does, so exact tranquilizer-weapon shot counts stay undocumented at every level, not just Level 1.

 

Taming Foods and Quantities by Level

 

 

    Preferred kibble is Exceptional Kibble, which "fills up 80 food per bite." Ingredients: 1× Extra Large Egg, 5× Fiber, 1× Focal Chili, 10× Mejoberry, 1× Rare Flower, 1× Water. Quantity and time needed scale by wild level: Level 1 — 5 items, 0:10:40; Level 30 — 8 items, 0:17:03; Level 60 — 11 items, 0:23:27; Level 90 — 14 items, 0:29:51; Level 120 — 17 items, 0:36:14; Level 150 — 20 items, 0:42:38. Arithmetic: Level 1 to 150 is 20 − 5 = 15 more kibble pieces and 0:42:38 − 0:10:40 = 31 minutes 58 seconds longer.

 

    At Level 1, crop alternatives run: Fresh Barley — 44 items, 1:10:24; Fresh Wheat — 44 items, 1:10:24; Soybean — 44 items, 1:10:24; Dried Wheat — 44 items, 2:20:48; Mejoberry — 58 items, 1:09:36; Berries — 87 items, 1:09:36. That same scaling continues at higher levels — Level 150 Fresh Barley needs 193 items, 5:08:48, which is 149 more items and, by arithmetic, 5:08:48 − 1:10:24 = 3h58m24s longer than Level 1. So kibble's roughly-hour advantage over crops at Level 1 only widens at higher levels. Two middle columns per food row beyond quantity and time aren't clearly labeled in the source extract at any level, so only quantity and time are stated here. Once tamed, ongoing preferred food is listed simply as Crops.

 

Base Stats and Growth

 

 

    Base values at Level 1, wild, per-level increase in parentheses: Health 870 (+174/level), Stamina 300 (+30/level), Oxygen 150 (+15/level), Food 3000 (+300/level), Weight 365 (+7.3/level), Melee Damage 52 (+2.6/level), Torpidity 925 (+55.5/level). Movement Speed is a flat 100% with no per-level wild increase, only a taming bonus. Head damage multiplier is x1.5, and "on ARK: Survival Ascended body multipliers also apply for player's melee attacks" too.

 

    Each level-up also grants a harvesting-level point, spent on Delicate or Power affinity — up to 88 points, maximum 165.7% in one category. Power harvest favors Wood and Rare Mushrooms; Delicate favors Thatch and Organic Polymer. Attacks: Claw Strikes for 52 damage (armor coefficient 0.4, every 0.67s), Cut for two 5-damage hits (10 total, every 1.16s), and Bite C for 42 damage that "applies half the damage dealt as Torpor instantly," usable every 0.67s and able to damage a rider.

 

Breeding Timeline, Saddle, and Loot

 

 

    The Therizinosaurus Saddle unlocks at Level 69. A kill grants 72 XP, and it always drops Therizino Claws — Special Loot Chance is a flat 100%. Drag Weight is 250; Feces Size is Medium.

 

    Breeding: Incubation Range 26–32°C / 79–90°F (Egg Incubator at 29°C / 84°F also works), Incubation Time 1h 39m 59.521s, Baby Time 11h 34m 26.666s, Juvenile Time 1d 22h 17m 46.662s, Adolescent Time 2d 9h 52m 13.328s, Total Maturation Time 4d 19h 44m 26.656s — just under 4 days 20 hours end to end. Breeding Interval is 18h to 2 days. The wiki's own framing: "A well-bred Therizinosaurus is arguably the most useful tame in the game," able to harvest almost everything except Stone, Flint, Metal, Obsidian, Gems, Silica Pearls, and Element Ore.

 

    Exact wild spawn coordinates are undocumented — the page lists it across many maps (The Island, The Center, Ragnarok, Extinction, Valguero, Genesis: Part 1, Crystal Isles, Genesis: Part 2, Lost Island, Fjordur, Midgard, Jotunheim) with a common/rare/cave legend but no coordinates in the extracted text, only that it's "found wandering around alone, though it is not uncommon to see them in small groups of 2 or 3." What's undocumented is narrower than it might sound: Level 1–150 kibble/crop quantities, taming times, and torpor-depletion rates are all cited above — only the weapon behind each KO figure, the two unlabeled middle food-row columns, and exact spawn coordinates are missing from the extract.

 

Trap before you tranq. Use a 2x2x2 trap, bring a fast mount (Procoptodon, Beelzebufo, or Utahraptor) to kite it there, and carry at least 100 biotoxin or several hundred narcotics — Level 1 torpor drains in under six minutes (2.84/s), and it only gets faster to manage at higher levels, up to 9.78/s at Level 150.

 

Running your own ARK server

 

    A Therizinosaurus tame is a real time investment once you count the taming window — over an hour on Fresh Barley even at Level 1, several hours at Level 150 — plus nearly five days of breeding time for a bloodline. A dedicated, always-on ARK server means your trap, your kibble ingredients, and your incubating Therizino Egg are still there when you log back in — no competing with a host's schedule or a public server wiping your stockpile overnight.

 

Conclusion

 

    Taming a Therizinosaurus comes down to what the wiki documents: it's a knockout tame with Torpor Immune set to No, Exceptional Kibble tames a Level 1 in about 10 minutes 40 seconds against roughly 70 minutes for crops (scaling to 42 minutes 38 seconds of kibble at Level 150), base Torpidity starts at 925 and drains at 2.84/s at Level 1 rising to 9.78/s at Level 150, the saddle unlocks at Level 69, and full breeding maturation takes just under 4 days 20 hours. Exact tranquilizer-weapon shot counts and precise spawn coordinates aren't in the source extract and aren't guessed here — the Level 1–150 food and torpor figures are documented above, not among the gaps.
