Silvanna's playstyle revolves around aggressive initiation, target isolation, and sustained magic damage. Given her offenseMagical score of 70, your primary goal is to maximize your magic damage output. Always look for opportunities to initiate fights with your Imperial Justice (Ultimate), especially on isolated or high-priority enemy targets. The ultimate provides a powerful lockdown and a significant boost to your attack speed and lifesteal, allowing you to sustain through the initial burst.
Once you've engaged, immediately follow up with Spiral Strangling (Skill 2). This skill is your core damage dealer and the fastest way to apply and stack marks from your Knightess' Resolve (Passive). Remember that your passive causes you to deal 30% extra damage to enemies with max marks, so prioritize getting those stacks up. The shield from Spiral Strangling, combined with the lifesteal from your ultimate, will help you survive while dishing out damage.
Use Cometic Lance (Skill 1) strategically. It can be used to close the gap for initiation, to stun an enemy trying to escape, or even as a repositioning tool to adjust your stance within the fight. Given her durability score of 50, while decent, it's not exceptionally high for a frontline fighter, so avoid diving into multiple enemies without your ultimate ready. Her difficulty score of 20 means she's forgiving, allowing you to focus on good decision-making regarding when and where to engage. Always be mindful of your positioning within the Circle of Light; while it grants lifesteal, you can still be overwhelmed if focused by too many enemies.
