Something I forget to mention, not all monsters will limp when they're weaken. For example,

Diablos = Rarely limp, sign of weakness is it'll constant goes into rage mode every time you land a single hit on it, doesn't matter if it's from you or from small minion monsters. Even a single silly kick will send him into rage mode.

Monoblos = Again, rarely limp, sign of weakness is it won't goes into rage mode anymore when it's weaken

Piscine like Plesioth or Cephadrome fins will be flat down. Volganos body will stopped glowing red, Carapaceon like Daimyo & Shogun will stop producing foam in their mouths Most Wyverns and Primatius will just start limping away when they're already weaken. You have to pay attention to all this sign if you're aiming to capture a monster.

To capture Lao Shan Lung, you'll need a 4 hunters team and place 4 stun traps and make sure all his legs stepped on them.

(K, last one was just meant as a joke lol...) <<

True hunters don't need those lol.
