Ceadeus Guides

Trip to the Final Showdown
If you read the wikia summary about Ceadeus, it says the attacks are mostly tail flicks and what not. They're suppose to not be directed at you. In my case, that was wrong. The Ceadeus may occasionally stop and perform the "coill up and launch self at you" attack like most levathans can perform. On the way, it will stop in a large open area and fire some water based "Hyper Beam" at you. After that, it will proceed towards the final area. The best area to attack is either the right horn (Big Horn that covers eye) if you want to carve it or it's mane if you just want to cut it up (Impact DPS can attack head, check the damage diagram on Ceadus provided by Lord Grahf + Inkoseh). Attacking other body parts may leave you vulnerable to the tail flicks and what not that CAN deal a hefty sum of damage if your ill-prepared. Useful food skills are Bulldozer if your going for the horn. Useful but not needed is 'Speed Gathering' for the Final Showdown.

Final Showdown
When you reach the final area, you will be near a pile of boxes containing nothing but rations. Look for similiar boxes else where, mainly the ones near what looks like a huge crossbow (bastillas). Attempt to gather every single ammo and fire them at the Ceadeus's Right Horn or it's head. If you miss more than a few, you might not be able to repel it on the first go. There are a total of 2 bastillas along with an equal amount of rounds. Use them carefully and move to the next Bastilla when Ceadeus gets too close. Also, near the top, you will see two (iron? rock?) pointed pillars along with a reddish button near by. Lure the Ceadeus near the two pillars and quickly pounce on the button. The Dragonator will activate, causing massive amounts of damage (Hopefully) to the Ceadeus. Note you may only have one shot at most on your first round, as it reloads extremely slowly. If you use up all the rounds and the dragonator, your last weapon is whatever you have in your hands, and your head. Focus attacks on parts of the head and be prepared to heal any damage you take (Please at least attempt to block/dodge, Rambo'ing is discouraged). You may wish to pop some dragonfell berries to remove the Curse status affects which gives you "Negative Critical Hits" and to bolster your resistance. When the timer runs out, depending on how much damage you inflict, you may get a repel or a mission failure. Damage carries over to the next quest, so a few bastilla rounds and another dragonator should finish the job.

Final Notes : I've misspelled a lot of words, so please correct them. Too tired to bother correcting them.
