I've put a question mark on this, because with the UNGODLY AMOUNT OF FISHING required to even summon it, I don't have enough data points to be sure. But... If you summon Charybdis with the Oracle Of The Seas, we worked out it's placed in a spot on the subserver the summoning occured at. On my first attempt and on my third attempt, I summoned on the Britain sub server, and it placed him in Britain Bay both times. I can't find the exact co-ordinates now from the first try, but it was definitely very close to the third which is pictured below, and within the Guard Zone. As you can see, I'm also carrying the Oracle Of The Seas. My character is a Legendary Fisher (120 skill) and was using the Fishing Set equipment with full bonus on every cast. Now, I used a total of NINE baits here to pull Charybdis, 5 on the first attempt, and 4 remaining from the second try here, and not once was Charybdis pulled. Every time I got the "Bubbles but no Charybdis" failure message, and a deep sea fish, but he wouldn't rise. However, on the second attempt, NE off the coast of Moonglow, we got Charybdis on the first cast. From what I've read of the few who've managed to get bait and Oracle, they seem to be getting him first try too. So either it's possible to fail the casting, or this particular spot within Britain Bay is invalid. Considering the HUGE grind required to get the items, can you confirm if Charybdis is working as intended, and if it's possible to fail... or that people should avoid using the Oracle on the Britain sub-server if he is genuinely broken when summoned within the bay?
