A tank and Blunt attacker who Discards skills for Shield, draws attacks with Aggro, and hits back with Blunt skills. Sinking is secondary.
Core Mechanics
Discard for Shield: S1 Expend Knowledge and S2 Seal Shut each Discard 1 of his highest-ranked skills on use. His defense skill, Fixated Study, Discards 2 random skills in ascending rank order. A Discarded skill grants Shield equal to Insight × a percentage of his Max HP; Discarding S3 Grace of Knowledge gives the largest percentage, 9%/12%. Insight becomes the rank of the last skill Discarded. Slash-separated values indicate different Uptie tiers.
Aggro: S2, S3, and defense give their slot Aggro next turn: 3 from S2, 8/10 from S3, and 3/5 from defense.
Main Blunt attacks: S2 has 3 Coins and S3 has 4. S3 does not Discard, so using it does not grant Shield. S3 gains +1 Coin Power below 50% HP.
Combat passive — Sinking Knowledge (3 Sloth Owned; unlocked at Uptie Ⅱ): When taking damage, inflicts 1 Sinking on the attacker. While he has Shield, inflicts 1 additional Sinking, up to 4 times.
How to Use
Use S1 and S2 to Discard high-ranked skills, gain Shield, and draw further into his skill pool. Faster cycling also lets him use his stronger S2 and S3 more often. Draw attacks with the Aggro from S2, S3, or defense, absorb them with Shield, and deal Blunt damage in return. Sinking Knowledge adds a little Sinking each time he is hit, but treat it as a bonus. Losing a Clash against an enemy with little Sinking can instead restore that enemy's SP; there is no need to give up Clash Wins just to trigger the passive.
