If you were properly geared out for the Ardyn vs Ravus achievement, you'll likely be properly geared out for this achievement as well. I feel that this one is still slightly harder than the Ardyn and Ravus fight. It's less chaotic because you're only fighting one NPC as opposed to two. This solution is mainly meant as a guide on several things to keep in mind when fighting him; you'll still need some skill to kill him. Obviously with more people, it'll be easier so if you're trying to beat him solo, it'll be a real challenge.
First off, I honestly don't think your gear makes that much of a difference. It seems like his coding and his moves is literally meant to one-shot you. I had 2,000 strength and 7,878 HP and I still got one-shotted by most of his moves. All you need is the Rampage sigil (you should be doing at least 5,000+ damage each time you activate this with
), patience and consistency.
*Having 100% bullet resistance negates all his machine gun damage so if you have this, and you see him pull out his machine gun, go to town on him.Several things to keep in mind before I discuss his moves.
-Always stay a medium distance from him. Most of his attacks hit centered on him to either close or medium range. Only his rocket launcher and giant sword instakill hit long range but both are easily dodgeable.
-Never use a warp point to regain health and mana. It's pointless. You should be regenerating mana fast enough anyways because the important thing is to keep an eye out for where he is at all times.
-After performing a move, Kenny is vulnerable for about 5 seconds. This is Kenny's window of vulnerability.
-Stay at his side or back. Never in the front. Most of his moves are frontal attacks and PBAOE (point blank area of effect).
-If playing with other people, consider having 1 person at long range on standby doing revive duty if people go down. Never group up on him unless he's recovering from an attack and you guys are on him going to pound town. After that, split up and wait for his next window of vulnerability.
-Never warp strike to him. He WILL grab you and beat you to 1% of your life. With that said, since warp striking is out of the question, what you will do a lot of instead is rolling by pressing X. This will let you dodge his attacks and close the distance. It's imperative that you roll out of the danger rather than jumping away. Rolling IIRC does have some i-frames albeit minor ones but still very important.
-The pillar in the middle is a great place to take cover from his projectiles and many of his other moves except for his giant sword instakill which I'll get to soon. I mainly used this pillar to recover from the Danger state.
-All Creation (LB + RB): the move that you can perform if your circular bar is full at the bottom does absolutely NOTHING to Kenny. Don't bother performing this.
**EDIT: Allgorhythm states "What you said about the All-Creation ability is spot on. Kenny is immune to it in the same way that Zu and Omega are immune to it. Nevertheless, you are invulnerable while using it. So, you might want to use it defensively rather than offensively. For example, if you have a charged gauge and Kenny back flips away from you, rather than roll dodge you can unleash All Creation and continue the attack against Kenny.
All Creation will protect you from all attacks including the giant sword. If one has become proficient in the use of All Creation in Ardyn/Ravus and Level 99 Bahamut, it can be very useful. On the other hand, if you haven't used it much and are uncertain of the timing, its better to rely exclusively on Roll/Dodge that can phase through any of Kenny's attacks."**
This is a great tip if you don't feel confident in dodging some of his attacks especially his giant sword beam. Use at your own discretion.Kenny Crow's Moves and Your Actions:
He starts off at the top of the pillar: Do not warp strike to him PBAOE Circular Slash:
if you're medium distance, you'll be fine
*I believe he also has 1 or 2 more sword attacks but if you know/can dodge this one, you can dodge the other ones as well since they more or less are the same. Sword in hand (1):
Shoots lasers out of his eyes at his feet in an arc - attack him from behindSword in hand (2):
Shoots lasers further out from his eyes in an arc - attack him from behindMachine Gun:
If you have 100% bullet resistance, go to town on him. If you don't, dodge-roll to the pillar for cover. (I honestly have no idea how much damage this does. If you have 100% resistance, it just says invulnerable for you.)Rocket Launcher:
randomly shoots 1-5 rockets straight ahead of him - dodge to the side and close the distance to attack his back. If you have 100% resistance, this does nothing to you as well.Molotov Bottle Explosion:
it appears he holds his stomach and throws a bottle to the ground when this happens - this was pretty rare for me. He didn't do this very often for me. Again, medium distance will keep you safe. You should only close the distance once you spot a window of vulnerability.Blue Wing/Aura Phase:
(this phase can repeat itself multiple times if the fight takes too long, he went into this phase 3 times when I fought him)
*He can heal himself in this phase (up to 20% is what I've seen) - best thing you can do is not to let the blue aura intimidate you. He's more or less the same in the first phase. Keep your cool and keep watching out for the windows of vulnerabilities.PBAOE Circular Slash:
still has this, same stuff. Medium distance.PBAOE Sword Slam:
he jumps in the air and slams his sword into the ground - medium distance.Giant Blue Laser Beam:
like the red lasers from phase 1 except with an important difference. Wait for him to shoot this laser then attack him from behind. Reason being is because the moment the laser shoots, the backblast reaches the hitboxes behind Kenny hitting you if you're behind him so just wait till he shoots it then attack him.Machine Gun:
no change, same as before - attack or hide if resistance is not 100%Rocket Launcher:
no change, same as before - strafe to his back and attack or face tank it if you have 100% resistance.Giant Beam Sword:
he holds his sword up in the air and a blue beam of light will charge it and he will slam it down on you (this move homes/tracks in on you), easily his most devastating move but pretty easy to dodge if you time it right- stand close to him, and the moment he swings it down, dodge-roll to his right or left and attack him during his recovery (window of vulnerability).
TLDR version: stay at medium distance until an attack animation is done, have patience, attack only during windows of vulnerability, never warp strike, never use warp points to recover health/mana, use pillar in the middle for cover, and abuse dodge-rolling to close distance or run away.
Hope this helps everyone with this. If there are any questions or comments that I can do to improve the solution, let me know. Thanks.
