Match the knockout tool to the target’s torpor, not to whatever is in your hotbar. Torpor is the hidden meter that builds until a creature falls unconscious; every knockout weapon adds a set amount, and using one that is far too weak means a long chase while the dino wakes or flees. A slingshot that drops a Dilo will get you killed on a Rex.
Target to tool: the working table
| Target | Use | Why |
|---|---|---|
| Small, low-torpor creatures (early game) | Slingshot, wooden club or tranq arrows | Cheap and enough to topple light targets |
| Tougher mid-size creatures | Crossbow with tranq arrows | 70 instant torpor plus 87.5 over 5 seconds |
| Very large, high-torpor creatures (Rex, Giga) | Longneck Rifle with shocking tranq darts | 312 instant torpor plus 130 over 5 seconds |
So read the top row as “what you can afford early” and the bottom row as “what a Rex actually needs”. The crossbow and longneck numbers come from knockout tables, and the jump between them is large: a shocking tranq dart is built for high-torpor creatures that a tranq arrow would take far too long to drop. If you only have early-game tools, tame small targets first and come back with a longneck rather than dumping a full quiver into something immune to it.
Root or trap the target before you fire
A creature that runs while you shoot wastes torpor and often escapes into worse terrain. A bola roots small creatures in place for 30 seconds, which is enough to land the first volley safely — but large creatures such as a Rex are immune to it, so for those you need a trap or a terrain corner that holds them while you work.
The order that works: restrict movement first, then apply torpor, then watch the meter. Keep food in the last hotbar slot so you are ready to start the tame the moment it drops, and never begin the knockout on a target you cannot keep still. This is the step players skip when a tame turns into a chase across half the map.
The over-tranq trap
More torpor is not automatically better. Over-tranqing — pushing excess torpor damage into a target — lowers taming effectiveness, which costs you the bonus levels a clean knockout would have earned. Use the right tranq for the target and stop firing once it is about to go down; a shocking dart on a small creature is the classic way to ruin a tame you otherwise had.
Our taming effectiveness guide explains what that lost effectiveness costs you in the final stats. The practical rule is to pick the lowest-tier tool that still knocks the target out in reasonable time, rather than the biggest one you own.
Passive tames are a different decision
None of the above applies to creatures that are tamed passively, without being knocked out at all. For those, the tool table is irrelevant and the job is approach, feeding and patience instead. Confirm which method your target uses before you gather narcotics and darts — the taming guide walks through both paths, and our tips and tricks has the smaller handling details that save a failed attempt.
