The Lunar Conservator
The Lunar Conservator Champion Loadout
For every action, there is an equal and opposite reaction. When Amius aims to create chaos and destruction in our rotation, our beloved Sethallia here is brought to restore order and conserve the peace. She is a well built champion that compliments this fight nicely. Bringing a lot of utility and some damage.
Her entire kit plays really well throughout this entire fight. She does buff removal, which isn't crucial to this fight but is definitely something that makes it a lot easier, smoother and it's the reason why I would bring her to this fight. She can cleanse one ally and place Block Debuffs buff on them as well as a heal that can also be a teamwide heal. This can come in handy. Her A1 has an HP Burn on it as well, which comes in really handy for some extra damage in this fight.
Does this champion need to be booked to work? No. I've won this fight without her being booked. Does she need to be booked to guarantee her buff removal? Yes and the fight is much smoother when it works. I recommend at least booking her A3 for this fight and maybe even her A1 if possible.
Strategy Description
Her main use for me is to remove buffs from Amius after he has flipped his debuffs into their buff form, after using his A3 Rampant Chaos, while in his base form. Then to land HP Burn on her A1 to contribute some extra damage. She can also be used to heal/cleanse at any point during the fight that you feel you may need it as a bonus. Her A2 heal can be crucial if used on a team that lacks other healing options.
Artifacts Description
I went with the Perception set times three due to the fact that Sethallia is often very good in the arena and maybe you would want that dual use out of her. Of course if you can get enough accuracy without needing Perception and didn't want to use her in the arena, then maybe something like the Toxic set could work but you could always just jack up her accuracy and speed through the roof and use her for both areas.
All that really matters here is the stats meet the thresholds. We want 250+ speed and 450-ish accuracy. If she is booked, all the better. If you can get her health and/or defense high enough to live without the HP chest piece, you could always go with an Accuracy chest. Just depends on your available gear.
* Some artifact sets have upgraded versions available. If you have a better upgraded version of this recommended artifact set, definitely use that instead.
The main goal here was to get to Eagle Eye. I grabbed all the accuracy masteries on the way down. As well as Evil Eye for the arena. Master Hexer and Sniper will help with the HP Burn.
On the defense side I like Defiant, Improved Parry and Rejuvenation. Resurgent, Shadow Heal and Delay Death all make great additions as well to help keep Sethallia alive throughout the fight. I went with Retribution last to help land a possible HP Burn debuff. The more attempts, the better.
Brimstone
Brimstone
Level 1 Blessing
Brimstone is still one of the best blessings you can have against Amius. She has the accuracy to land it, which is important here. That's probably all that matters and why she makes a great choice to have it. You can always save other blessings for other champions. At the one star level, it doesn't do much but all that you can get will help.
Level 6 Blessing
The higher the blessing level the better. Brimstone is still a very obvious choice here due to the accuracy requirements.
