Quick Answer

Capture when the quest allows it, the monster is weak enough, and you want to end the hunt safely. Slay when the objective demands it, when a monster cannot be trapped, or when your party still needs part breaks. The basic flow is simple: weaken the monster, trap it, then use tranq items before it escapes.

Capture Flow

StepCheckCommon Failure
1Monster is weak enoughTrap is placed too early
2Quest allows captureObjective requires slaying
3Trap works on the targetMonster or state ignores that trap

In multiplayer, signal before capturing. Many failed captures happen because one hunter starts the trap while another keeps attacking at full pace.
