Arknights: Endfield Si Rotation Guide – How To Play Si Properly

Arknights: Endfield Si Best Teams

Upon using her battle and combo skill, Si can apply the immobilization and Artful Intent debuff on enemies, allowing the team to deal powerful damage to enemies. Si’s battle skill allows her to apply the Artful Intent debuff on enemies, which records the damage taken by enemies over a period of time and deal powerful damage to enemies proportional to the amount when it expires. Additionally, this skill also allow Si to apply an Elemental Infliction on the enemy based on the element of the 1st Operator in the team. Si’s 2nd stage Battle Skill allows her to summon an Ink Soul from the enemies, allowing the team to deal damage to the Ink Soul and all damage taken by the Ink Soul is transferred to the enemy. Si’s 3rd stage Battle Skill allow her to destroy the Ink Soul early, triggering a powerful explosion effect similar to the Artful Intent damage effect. Whenever the enemy’s Heat or Cryo Infliction is consumed, Si uses her Combo Skill, summoning a powerful Lung and dealing powerful Cryo damage to enemies.

Finally, upon using her Ultimate, Si will summon a Lung on the battlefield that deals periodic Cryo damage to enemies in addition to providing the entire team with Heat and Cryo Amp effect and shorten the Combo Skill Cooldown of the Operator in the 1st slot, allowing her to massively boost the team’s damage output and shorten the DPS’ damage rotation downtime.

Important Notes When Playing Si

Si is a very interesting character with a lot of important gameplay notes that players should pay attention to when playing her:

– Use Her Battle Skill Twice In a Row To Activate The Damage Sharing Effect: One of Si’s main strong point is her ability to create a damage sharing Artful Intent upon using her battle skill twice on an enemy, allowing the entire team to deal damage to the enemies from a safe distance by attacking the Artful Intent instead. To activate this effect, players will need to use Si’s Battle Skill twice, consuming around 115 SP in the process. It is important to note that if the enemy and teh Artful Intent is near each other, using AoE attacks that hit both will essentially means that players are able to deal double damage to the enemy, making it crucial for players to activate this Artful Intent effect when able to.

– Ends Artful Intent Early Is Good Sometimes: When Artful Intent is on the field, Si will not be able to use her 1st stage Battle Skill to apply Cryo or Heat Infliction on the enemies, which might prove the be problematic when players wants to apply those infliction to trigger combo skills for other operators. Therefore, players have the option to end Artful Intent early to trigger the additional damage effect onto the enemy by using her Battle Skill again. This not only helps to allow Si to use her Battle Skill stage 1 again but also allows players to deal quick additional damage to the enemy to finish them off if players are in a time challenge.

Best Teammates For Si

Now that we have gone over the some of the important gameplay notes for Si, here are some of the best teammates players should pair her with:

Arknights: Endfield Arcane

– Arcane: Arcane is Si’s best teammate and should be used together with Si in any Heat or Cryo team to optimize both characters’ performances. Not only can Arcane follow up Si’s ability to apply Inflictions onto the enemies with her Combo Skill to apply another stack of Infliction, she can also consume the Cryo Infliction on the enemies with her Battle Skill to trigger Si’s Combo Skill. Additionally, Arcane provides an amazing Cryo susceptibility effect to the entire team, boosting Si and the Cryo team’ damage output massively and she can also benefit immensely from Si’s Combo Skill Cooldown cut effect.

Arknights: Endfield Yvonne

– Yvonne: Yvonne is one of the Cryo Main DPS characters that benefits the most from Si, especially with her Artful Intent effect. Not only can Si provide Yvonne with her much needed Cryo Infliction Stack and boost her damage with Cryo Amp, Si’s Artful Intent helps to completely remove Yvonne’s weakness of lacking AoE attacks, with her now being able to focus on targeting the Artful Intent to deal powerful damage to multiple enemies at a safe distance. Yvonne can also consumes Cryo Infliction on the enemies to trigger Si’s Combo Skill to deal devastating damage to enemies.

Arknights: Endfield Last Rite

– Last Rite: Last Rite is another of the Cryo Main DPS characters that benefits greatly from Si, with Si’s ability to quickly apply Cryo Infliction and Cryo Amp massively boosting Last Rite’s damage output. She can also consume Cryo Infliction on the enemy to help trigger Si’s Combo Skill as well.

Arknights: Endfield Laevatain

– Laevatain: Laevatain the Heat DPS character that benefits the most from Si’s effects, with her able to take full advantage of Si’s Heat Infliction application effect, heat amp and her also being able to trigger Si’s Combo Skill easily with her Heat Infliction consumption on final strike.

Arknights: Endfield Rossi

– Rossi: Rossi is another DPS character that can benefit decently from Si’ ability to apply Heat Infliction and Heat Amp to optimize her damage output. More crucially, Si’s Combo Skill Cooldown reduction effect can help Rossi to do her Combo Skills consecutively.

Arknights: Endfield Xaihi

– Xaihi: Xaihi is an excellent Support/ Sustain character for any Cryo teams and she works extremely well when paired together with Si, not only boosting her overall damage output and supply the team with extra Cryo Infliction, Xaihi can also provide healing for the team and additional damage boosting effects, allowing Si to become a main DPS if she so choose.

Arknights: Endfield Si Best Teams – Best Performing Teams For Si

As a DPS Support Character who can provide the Cryo and Heat teams with amazing utility effects, she works wonders when in the same team with powerful Heat DPS and other support characters to optimize the team’s damage rotation. Si herself can also become a main DPS of the team depending on the team comp as well.

Heat Team

LaevatainSiArcaneCamille
Main DPSSub DPS/ SupportSub DPS/ SupportSupport

This team is Si’s Best Heat team that takes full advantage of her Heat Infliction Application effect and her Heat Amp. It is important for players to put a Heat character in the 1st position that can take advantage of Si’s Combo Skill Cooldown Reduction effect, due to Si needing a heat character in the 1st slot to inflict Heat Infliction with her Battle Skill.

Main DPS: The main DPS for this team is Laevatain, with her ability to take full advantage of Si’s Heat Infliction and Heat Amp in addition to being able to reset her combo skill cooldown with Si’s Cooldown reduction effect on Ultimate. This spot can be replaced with Rossi, however, the team comp will need to be changed significantly if she is the team’s main DPS.

Sub DPS/ Support: Si and Arcane serves as the team’s pair of Sub DPS and Support, with both of them being able to apply stacks of Heat Inflictions to allow Laevatain to consume to trigger her skill rotation while also dealing massive amounts of damage and provide the team with various utility effects like Amp, Susceptibility, Haste and more. If players don’t have Arcane, you can use Gilberta or a support character in this slot instead.

Support: Camille’s is the team’s main Support and Enabler, with his ability to both inflict Heat Infliction and Heat Susceptibility on the enemies in addition to providing the entire team with SP recovery needed for the damage rotation to become smoother. If players want to have a sustain in the team, you can replace him out with a sustain character like Ardelia. If players uses Rossi as the team’s main DPS, then this spot will be filled with Gilberta instead.

Cryo Team

Main DPSSub DPS/ SupportSub DPS/ SupportSupport

This team is Si’s best Cryo team if she is used as a sub DPS Support character, with either Yvonne or Last Rite acting as the team’s main DPS to take advantage of Si’s Cryo Infliction and Cryo Amp effects. Do keep in mind that since this team doesn’t really have a Vanguard option, SP management is extremely important when playing this team.

Main DPS: The Main DPS options for the Cryo team is between Yvonne and Last Rite, with both characters function somewhat similarly, requiring the players to inflict 4 Cryo Infliction stacks on the enemies then using their abilities to consume them to trigger their damage rotation. 

Sub DPS/ Support: Si and Arcane serves as the team’s pair of Sub DPS and Support, with both of them being able to apply stacks of Cryo Inflictions to allow Yvonne and Last Rite to consume to trigger her skill rotation while also dealing massive amounts of damage and provide the team with various utility effects like Amp, Susceptibility, Haste and more. If players don’t have Arcane, you can use Gilberta or a support character in this slot instead.

Support: Tangtang serves as the team’s last slot, capable of providing the team with additional Cryo Infliction stacks and various other beneficial effects. If players want to have a sustain character instead, then they can use Xaihi in this spot instead of Tangtang.

Si Main DPS Team

Main DPSSub DPS/ SupportSub DPS/ SupportSupport

This team uses Si as the team’s main DPS, with the main goal of the team revolving around triggering her Combo Skill and Ultimate as many times as possible to allow her to deal powerful damage to all enemies. The damage rotation and team building is a lot stricter with this team, requiring players to have all of the characters listed in order for this team to work. This team needs to apply enough Cryo Infliction stacks onto the enemy, then consume them by converting them into Nature Infliction stacks with Arcane to trigger Si’s Combo Skill to deal amazing damage to enemies.

Main DPS: Si serves as the team’s main DPS in this team, capable of dealing massive amounts of damage with her Combo Skill based on how much Cryo Infliction stack is consumed by the team in a single instance. Players will ideally want Si to trigger her Combo Skill whenever 4 stacks of Cryo are consumed in order to optimize her damage output.

Sub DPS/Support: Arcane is the team’s main enabler and support characters, capable of providing the team with an additional stack of Cryo Infliction, Cryo Susceptibility on the enemies and most crucially, is the character that will convert the Cryo stacks on the enemies into Nature Infliction stacks with her Battle Skill, consuming them and triggering Si’s Combo Skill to do damage. 

Tangtang works as an additional character to apply Cryo Infliction onto the enemies and inflict them with Arts Susceptibility, allowing the team to deal more damage.

Support/ Sustain: Xaihi is the team’s main support and sustain character, capable of also providing the team with Cryo Infliction and Cryo Amp in addition to healing, helping to optimize the team’s damage rotation and damage output.
