• Sworn Lance isn’t a bad weapon by any means. Being able to grant upwards of 12 Atk and Def on top of negating follow-up attacks and having Armor effectiveness can make him a fantastic Armor check in general as most armors that rely on skills such as Bold Fighter don’t have good Spd, to begin with. However, outside of Armor coverage, the weapon isn’t any better than something such as Stout Lance+ as the damage reduction and additional Atk and Def granted can allow Silas to take on even more physical threats and allow him to trigger higher cooldown Specials more consistently. Also, given his status as an enemy phase unit, his set options are going to be very limited. As such, this will be the only recommended set for him.
   
• Depending on the weapon of choice, Silas can either opt for a two-cooldown Special or a three-cooldown Special. Sworn Lance negates the foes’ follow-up attacks, so he won’t have the ability to charge up his Special any faster without some support present. Meanwhile, if running Stout Lance+, the foe will more than likely double him due to his low Spd, so he can charge up a three-cooldown Special such as Bonfire and inflict massive amounts of damage on the second hit.
   
• Silas would appreciate stacking up as much Atk and Def as possible. As such, three of the best options for him include Sturdy Stance, Atk/Def Solo, and Atk/Def Catch. Sturdy Stance, depending on the version, can provide a great amount of Atk and Def and inflict Guard on the foe in the enemy phase. Meanwhile, Atk/Def Solo provides a bit more Atk and Def and can work in both phases. For the most premium option, Atk/Def Catch will provide the most Atk and Def out of the three skills, but relies on debuffs on the foe.
   
• Enemy phase cavalry units lack a good amount of notable B Passive options. The only two worthwhile skills that Silas has access to are Lull Atk/Def and Quick Riposte. Lull Atk/Def is solid for overall tanking, but Silas is going to need Quick Riposte in his kit somewhere since he lacks the natural Spd to double on his own. If it’s not present anywhere in his kit, simply run it in his B Passive slot.
   
• Thankfully, there are plenty of C Passive options for Silas that can work really well with the rest of his kit. Joint Drive Atk is a standard option that works well as it grants additional Atk for being near allies, which he already needs to do since his PRF has a three-space dependency. Meanwhile, Rouse Atk/Def can work well if running a bunch of Solo skills, and Atk/Def Menace pairs well with Atk/Def Catch.
   
• Depending on the B Passive running, Silas will either want to run Quick Riposte or anything that increases his Atk and Def. Quick Riposte is important for securing doubles as Silas lacks the Spd stat to securely double himself. However, if it’s being run in the B Passive, using a Sacred Seal such as Atk/Def Solo is a good option for him.
