A Slash attacker that discards S3 to reach 3 Insight, then relies on Coin reuse from S1 Expend Knowledge. Maintaining 3 Insight requires managing which discardable skills remain in his slots.
Core Mechanics
Insight: The rank of the last discarded skill (default 1). Discarding S3 makes it 3, S2 makes it 2, and S1 makes it 1.
S1 — Expend Knowledge: On use, discards the highest-rank skill in his slots. If there is no S3 in his slots but there is an S2, it discards S2, dropping Insight to 2. At 3 or more Insight, it reuses Coin Ⅰ and gains Clash Power (at Uptie Ⅳ, it reuses (Insight − 1) times and gains +(Insight − 1) Clash Power; at 3 Insight, 2 reuses and +2). Reuse happens when attacking, so the Clash uses 1 Coin.
S2 Unveil and the Defense skill Guiding Steps: Discard 2 random skills in ascending order of rank. The rank of the last one discarded becomes Insight, so discarding only S1s drops it to 1. S2 gains Coin Power at 3 or more Insight (+(Insight − 1) at Uptie Ⅳ).
S3 — Cyclical Knowledge: At 2 or more Insight, gains Coin Power equal to Insight and deals more damage based on the target's Sinking. It does not discard other skills itself.
Combat passive — Peering Through a Key (3 Gloom Resonance; unlocked at Uptie Ⅱ): When he discards a skill, gains Damage Up equal to its rank, up to 3 per turn. When an ally discards a skill of higher rank than his Insight, his Insight increases by 1.
How to Use
Use S1 (or S2) while S3 is in his slots to discard S3 and bring Insight to 3. After that, each use of S1 or S2 discards the remaining skills, and Insight drops if S2 or S1 is discarded last. Once Insight is 3, he can keep it there by replacing the lower-row skills with Defense skills and using only the upper row, leaving no discardable skills (Defense skills cannot be discarded). He also inflicts Sinking, but his core is sustained Slash damage.
