Overview

The Dead Heat Muscle Queen fight is notable in that it has a beneficial field effect, which grants an Arts Performance buff to all frontline Servants.
The stage itself consists of 3 waves, featuring mostly Saber enemies along with a Caster-class Sphinx on the first two waves, while Berserker of El Dorado herself appears with 3 Break bars in the final wave, accompanied by more Saber-class enemies. Berserker of El Dorado’s Break Bar effects improve her offense at the cost of her defense - although if her allies are kept alive(limiting her moves) the effects are very underwhelming.
The mobs themselves are fairly easy to deal with, especially if a strong Archer Servant is brought along, and while killing the Sphinx may take some time, it is not a big threat due to its 5-bar NP gauge.
Berserker of El Dorado on the other hand, is able to deal a lot of damage despite only getting two moves when left alone, and she is the stage’s primary threat. Indeed, a tricky Master may even keep the Amazon allies alive so as to give her only one turn to use (thus preventing a surprise NP or the critical hits from her first Break bar.
After all, her Break Bar effects actually use up one of her moves.
The mobs can be wiped out once the player is ready to burst down Berserker of El Dorado’s final HP bar.

Team Recommendations

Archer-class damage dealers are recommended for this stage, and while Arts-oriented Servants benefit more from the stage’s Arts buff, Buster-oriented Servants will also find their NP gain to be greatly increased.
Berserker of El Dorado also has a host of traits to abuse, such as Divinity or, if a Master is feeling adventurous, the King trait.
With that Arts buff as well, this is her moment to shine!
In case Masters do wish to go all out and eschew keeping Berserker of El Dorado's allies alive, Defense Up effects and Taunts are highly effective at mitigating her damage.
