Please do note that there is a shrine of order under the first bridge

Fun secret to the fight which I found out recently: if you managed to get grab a certain golden guardian’s item, in the final phase, he will assist you during the fight and most likely kick Mithrix’s ass. It also gets additional dialogue showing disbelief and fear

[vinity]

To maximize the fall damage on mithrix's first and third stages, jump over him right as he reaches the ramp. He will shoulder charge and end up lunging upwards trying to hit you. This results in him hitting the ceiling, dealing about 3/4 of his HP when executed flawlessly on eclipse 3 and higher.

Source: I have level 8 eclipse for several survivors completed.

Mithrix is the one reason I can justify playing artificer on multi lobbies with my friends, god she absolutely cheeses this fight

[bruceyoung]

First time I got there on “Hard” mode.
I wasn’t expecting his 1 shot potential straight hammer smacked me into oblivion the second i laid eyes on him

[calebo.]

You forgot something about the fuel cells

You still keep the extra charges, so long as you've saved them, even after he takes all your items

[naturallymoronic]

I personally find that taking a transcendence from one of the lunar pods before fight is a really good idea, as except for his gun, normally you aren't taking any damage, so if you mess up and get slammed or something, you're back up to full faster. The same is true for cautious slugs

[matteovukoja]

One thing note about Mithrix fight: the shockwaves deal a LOT of damage. Always be on the lookout for those.

[ravenwarjoy]

One thing you forgot to mention is that Rex's special entangles him, also freezing him in place.

[KnighTiggles]

I wouldn't mind a guide that goes over each survivor's strategies vs Mithrix.
Anyways, thanks for the video!

[BookwormCowboy]

Tangling Growth will root Mithrix and interrupt his attack cycle on all phases. Given it has almost no downtime, it makes REX rather effective against him.

My friends and I looked for the primordial portal for over an hour yesterday... finally to realize the update hasn't dropped on console yet 😤😫
Still great video Woolie and will help us a ton when it does drop

[WolfmanTheNoob]

Holy crap! Thank you! this was so well explained and helped me out a lot since I started playing again on counsel because I played this way back when and forgot everything I knew back then. Please keep up the great work

[stonebeard]

I’ve put 100 hours into ROR2 and used many of your videos as a resource and still learned a few things in this video. Thx for all the dedication and videos my guy!

IDK if many people will see this comment, but I wanna try and get some important observations I've found out into the public. First (because this is just a quick tip) when Mithrix begins using his orbs in phase 4 and you're on the ground with him like the go gamer you are :| then strafe around him in a COUNTERclockwise direction. It did not seem to be mentioned how the orbs always rotate counter clockwise (going out twice and disappearing on the outer edges of the arena after), so running in a clockwise direction is less than suboptimal because you can and will be blindsided by said "crit ice band proc." So, going the direction where you can see them is probably your best bet. Second, his dashes are very interesting in the way his cooldowns work. From my observations, you can think of them like survivor abilities, 2 dashes for movement, and one dash SWIPE. The 2 movement dashes are used for the diagonal dash combo, back dashing, general movement, and combo-dashing (where he dashes straight forward and then dash swipes after).When he swings his hammer after a dash, this seems to be on a different cooldown than other dashes, as he can use it after exhausting his 2 dashes. Usually, it's hard to count his dashes, and I haven't figured out the exactly cooldown. Though, he does have a general attack combo which is the diagonal dash-dash swipe, then a dash slam. After the dash slam he'll probably have at least one dash back, and usually dashes out of the slam position once finished. However, if he does 2 lateral dashes in rapid succession without dash SWIPING, it can be safe to assume his next attack will be a single dash swipe. Despite this, his dashes still manage to be very unpredictable at many points during the fight. Again, this is all purely observational, and I need to do some more testing to confirm this. However, this seems to be the case and works for me rather well when I can notice it. Hope these tips are helpful!

Amazinga. Great video, Woolie. Just what I needed to help me out on eclipse with my main man Commando. There is actually one thing that wasn't mentioned in the Advanced Tips section and that's the power of a scrapper + good 3d printer. If you are lucky enough to find a scrapper and a good printer on the same stage 1-2 stages before you head to Commencement, after you do the teleporter scrap the item you want to print to reset its place in the item bar so it's at the end, and so you'll get it back sooner against Mithrix (King of Nothing) even if it's just a couple stacks of it. This may seem kinda niche, but I've found that it works rather well for me. Even if you don't get this opportunity most runs, it is essential to always keep this in mind because getting good items back during phase 4 can almost trivialize the rest of the phase. Obviously look out for crit, bleed, AP rounds, etc. This tech has definitely secured me many wins in the last phase after the September patch. I also find that OWSK's are really nice to take, especially if you don't already have one and find it 1-2 stages before hand, or even on soup island. They drop agro and can buy you essential time during all phases.

If you go to him while having Artifact of Swarms on, there will indeed be 2 mithrixes. It's the real ending since you reunited him with his brother! (and then killed them both)

[MrNyoom]

something to remember: mythrix dashes cancel his recovery animation, his "second dash" with the hammer swing is an ability. the main dash has 2 charges. the hammer smash is the slowest and the recovery can only be canceled after he has hit.

[Some_Bunny]

Tip for Mithtrix: His biggest weakness is... himself. Seriously. Try Swarms with Chaos and watch them tear each other apart. (You do have to make them aggro on each other first.)
Also Vengeance Clones are deleted when you begin the fight.
