The One Horned Demon King...

God, this quest is pure death.

I was wondering, how does everyone else do this quest? I have a monoblos S/ Ceanataur S mixed set, with 412 defense, attack up L and sharpness + 1 with a Daora's Decimator greatsword, and I still can't beat it. I try to keep him completely locked down:

I have 15 flashbombs, 10 sonic bombs, and 3 shock traps.
After about 20 minutes, I get him limping, but after that he just mutilates me with any attack he uses.

Suggestions? I need to beat this bugger a few times to make the Diablo Destroyer D:

if it's just for materials the guildhall one is easier.

don't use an element greatsword. with GS you should always go with raw (xept for fatalis but thats another story).
i assume u are high-rank. at this rank the best would be maybe the nargaGS. at least it's one of the best.

keep blocking. use megajuice/powerjuice so you can keep blocking continuiously.

id recomend doing this if you arent trying to break the horns: https://www.youtube.com/watch?v=Lx1PViGnFe4&feature=plcp&context=C4c86623VDvjVQa1PpcFMUN809o2lf3MdL5kvf88xuwp_bVnYMHNM=

You are talking about the high rank one horned diablos quest , right? daaaaamn that quest is hard.... I almost killed it once with my true devil slicer (longsword , thunder element) and my death stench armor (ESP).... But then i died....
I would suggest going for his tail first as it just falls off... Also when he is in area 7 get him to charge when you are behind that rock in the middle of the area.... Stand at the rock's side and when you see him charge hide behind it... He will get stuck and will be vulnerable for a while.... Do it again and again and again and you will manage to get some hits in....
About the shock traps.... I think he cannot be trapped with those , because he will dig under them and destroy them.....

Shock traps work decently on him, BUT you are right about the breaking. you just have to be lucky really, hope he charges rather than digging (UGH whenever i fight a diablos he does NOTHING but dig...).

One nasty thing though is that (im fairly certain at least...) he often ignores you and digs straight for the trap to destroy it. really annoying.

yah when i fight him hes underground more than above

why bother doing the one horned for horns just do the normal one if you need mats @.@

I would never do this quest unless if it's a key quest (which I belive it is /mad/ ).

Do normal diablos for grinding instead of making things too hard for yourself.
