So this morning I was farming Agnaktor for his armour and on the third run the dot on the map started flashing (Capture Guru), so I hit him around for a few more minutes and then set my trap down and then he stumbles into it (The dot still flashing). I throw my tranq bombs, all three of them and nothing happens, he limps away into area 10...

Me and Chacha were just like

I once threw 5 tranqs at an ian and she still managed to limp off to area 10.
Turns out cha-cha and the altaroth were in the way.

i almost had the same problem, throwing tranqs at diablos, but i was only throwin 2, and he was in rage mode, so i didn't know it needed 3 >.> but idk what happened to u maybe agnaktor summoned a shield >.>

Sounds like you missed.

Have a nice day.

When I first tried to capture the great jaggi offline, I was afraid that I would be too overpowered, so I gemmed in Cap guru. When I caught him in the trap, I kept throwing tranqs, wondering when the heck he would fall asleep, then I realized the effing jaggi and jaggia were in the way.

As I recall if a monster is enraged it need 4 tranqs.

May sound dumb but is it possible you threw paintballs instead? I know it's hard to mistake the dark red for the pink but it could be in your haste you threw the wrong ones?

Definetly Tranqs, I am so sure that I had done everything right....

Obviously just a little malfunction, first one after 100 hours of play..

Well hopefully your next few runs wont have that problem.

I had this happen the other day.

Apparently I was trying to put a teammate to sleep as I hit him with 3 tranqs before the monster broke free from the trap.

Oops.

1 the monster could've healed over time (they do, yes)

2. you did miss the tranq bombs, or you hitted something else.

Capture guru wont lie, its probably one of the most unlikely things to glitch. if the monsters hp was bugged and he wasnt capture-able then capture guru wouldn't have blinked.

After reading this thread

When tranqs don't work start hitting it, don't worry about killing a monster when capture guru starts showing it's flashing, it mean it's weak, but not weak to the point it'll die in the next few hits (unless it's G.Jaggi and maybe G.Baggi).

But if a monster limps away you should never attack it when you're trying to cap it.

I've managed to capture monsters with two tranqs with cap guru, in and out of rage forms but I admit sometimes it takes 3 tranqs oddly enough, only time I had trouble with tranqs was with a Jho my friend had cap guru he said it was ready so i waited for him to come to the next area and well... Bastard just wouldn't sleep, although I only threw two tranqs while damn sure he wasn't in rage, and more than sure he was already limping mmm... actually I don't remember it that well *shrug*

imo, just tranq a monster until it's asleep if you're sure capture guru is active, although I always though the third tranq was for someone to throw if they screwed up the first time and missed or hit something else, but I 'guess' it could've been for enraged monsters *shrug*
