Nahda Nabiilah is a writer and editor from Indonesia. She always liked to write and play games, so one day she decided to combine the two. Most of the time, writing game guides is a blast for her because those are two of Nahda's favorite things. They strive to create detailed and easy-to-understand guides.

Best build for Rossi Arknights: Endfield is a mix of the Lupine Scarlet Sword paired with the MI Security Gear set. He uses Agility and Intellect as his two main attributes, so focus on those when crafting your Gears. Finally, since her ability revolves around Crit, she should also have enough Crit Rate to have consistent Crit hits.

Rossi Best weapons in Arknights Endfield

Weapon		Why is it good?
Lupine Scarlet		Lupine Scarlet is Rossi's best weapon Arknights: Endfield. Provides agility and critical speed, allowing Rossi to consistently deliver critical hits. His passive boosts both physical and heat DMG, which is perfect for Rossi's hybrid Physical and Heat playstyle.
A glorious memory		If you don't have enough moves for her signature weapon, you can purchase a Battle Pass A glorious memory. Like Lupine Scarlet, it also provides Agility and Critical Rate, but its passive is less impressive. Increases Ultimate DMG after using a vulnerability. Rossi deals tons of damage with her Ult, but it's not her only source of damage, so focusing only on her Ult isn't ideal compared to Lupine Scarlet's universal physical/heat bonus.
Sundering Steel		The best F2P option for Rossi is Sundering Steel. Increases Agility and physical DMG and grants ATK from passive. However, the lack of Crit Rate can affect Rossi's stability in battle.
Rapid rise		If you prefer to upgrade a 6-star weapon, you can also use Rapid rise. This weapon increases her main attribute and crit rate, which is perfect, but her passive is not that useful for Rossi. Rapid Ascent increases the physical DMG dealt through Battle Skills and Ultimate. Since Rossi only deals Heat DMG with his Ult, he loses that part of the buff. The sword also increases Battle Skills and Ultimate DMG against unlucky enemies, which Rossi can benefit from if you only save her Ultimate for when the enemy staggered.
Conditional measures		New players can temporarily opt for Conditional measures. It gives Agility and Physical DMG as its sub-stats and ATK from the passive.

Rossi The best gear in Arknights Endfield

The best Rossi gear set
The best set of gears		MI Security Armor T1 gives Agility and Intellect, perfect for Rossi. You also get Ultimate Gain Efficiency from it.
		Safety gloves MI T1 another Ultimate DMG upgrade, perfect sync with armor.
		MI T1 security range is a major item for Rossi. Increases Crit Rate, which is not easy to get. It's best to keep this part of her kit and not trade it for other things, even Ultimate related kits, as it's better to have consistent damage output compared to conditional effects.

Best Flex		Frontiers Armor T3 is the best flex-slot if you don't want to use it MI Security Armor T1. Increases Rossi's secondary attribute in exchange for Ultimate Gain Efficiency from the second set. This Gear is also cheaper if you are on a budget.
