◯ = Stat gains +4 with a superboon, ✕= Stat goes down by -4 with a superbane, - = No assets or flaws
| See the IV Checker for All Units | Trait Fruits—How to Change IVs |
When using an Ascendant Floret, we recommend getting the next superboon if it fits the hero. If not, consider what stat your hero needs most.
+Res/-Def
The best IVs for Knoll are +Res and -Def. Boosting Res improves Knoll's bulk and also improves his bonus damage from Dark Monograph.
Knoll's Def is a dump stat and can be safely taken as a bane.
+Res for a +10 Merge
We recommend +Res when merging Knoll up to +10 to improve his bulk and damage output at the same time. Due to his age, he will need as much help as he can get to compete with modern metagame units.

We recommend the Special Effect Refine for Dark Monograph
Refined Dark Monograph inflicts Atk/Spd/Res-10 onto Knoll's foe in combat and grants Knoll bonus true damage equal to 20% of his Res, Special cooldown charge +1 per attack, a guaranteed follow-up attack, neutralizes Atk/Spd/Res penalties on Knoll, and heals 7 HP after combat.
Refined Dark Monograph also inflicts Atk/Res-7, 【Panic】, and 【Deep Wounds】 on closest foes and foes within 2 spaces of those foes at the start of each turn.
This refine aims to cripple foes and buff up Knoll at the same time, giving Knoll multiple avenues of improvement which can be good or bad depending on his foe's ability to neutralize either.
