KAM Ready Requirements

Speaking as someone who can beat the mission but not consistently - feels hard to quantify the "minimum".
Relics, mods, knowledge/skills, and rng are all very important. I guess r5 across the board? And almost all the guides I've seen give some ideal ranges on health and speed you want to mod them to have. And then you need to understand the mechanics and have some basic idea about when to do what, so that you can at follow those flow charts you find.

I don't know what the no-tryhards minimum is. Full r8 maybe?

I think there was a video of r3 or r5 bad batch breezing through it

Iirc I was starting to get some consistency with an ~R4 average on the team with Shaak + Rex being on the lower relics and Fives + ARC being a bit higher (Fives stat sharing is super important and you wnat to have at least 1 of the damage dealers quite high). This was ofc with knowing how to play and putting optimized mod setups on that team.

I wouldn't try to go for a bare minimum. You might win with a full R2-3 team if the stars align but what's the point if that's the case in like 2/10 battles?

Advised minimum:
Shaak - R3
Rex - R3
ARC - R5
Echo - R3
Fives - R5

For more consistency:
Shaak - R5
Rex - R3
ARC - R7
Echo - R5
Fives - R7

Easy life:
Shaak - R7
Rex - R3
ARC - R8
Echo - R7
Fives - R7-8

I collected stats for KAM missions in a fairly high end guild when it was “new” & have the following advice:
—> Streaming support/personal expertise is the most important factor.
RECOMMENDATIONS: (based on 300 KAM attempts)
Assuming Zoom Calls/Significant Experience.
Minimum recommended gear
Echo AND Arc at R6 and R7 Fives
77% success rate
Upgrade Option 1 (Most Beneficial)
Upgrade Arc to R7
>80% success rate
Upgrade Option 2
R6+ Shaak Ti and/or(?) Avoidance Arrow with Speed
Secondary
>80% success rate
Do BOTH upgrades…..
>90% success rate

To explain Shaak Ti better:
R5 = 58% success rate (Dodge = 10.67%)
R6 = 81% success rate (Dodge = 14.25%)
R7 = 85% success rate (Dodge = 17.67%)
If Shaak Ti dies early your run is usually over. Higher Relics =
more H+P and >Dodge. Also, CArrow with decent speed
secondary gives 35% Crit. avoidance.
