Arknights: Endfield Si Rotation Guide – How To Play Si Properly
General Introduction
Si is a 6-Star Supporter Agent of the Cryo element that specializes in dealing Cryo damage to enemies while providing amazing Cryo and Heat buffs to allies and also inflict multiple powerful debuffs and amazing effects on enemies to optimize the team’s damage against enemies.

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:

– 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.

– 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.

– 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.

– 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.

– 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.

– 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.
