Young Soren

Weapon: Adroit War Tome

Assist: Positional Assist / Preference

Special: Iceberg

Passive A: Mirror Impact / Atk/Res Solo (3 or 4) / Atk/Spd Boosting A Slot

Passive B: Lull Spd/Res / Mystic Boost / Watersweep

Passive C: Time’s Pulse / Preference

Sacred Seal: Blade Session / Atk/Spd Solo / Swift Sparrow / Mystic Boost

• Young Soren is an excellent Player Phase mage thanks to his exclusive weapon: the Adroit War Tome. This gives him a hefty boost to his Attack and Resistance during combat, as well as effects based on how much higher Soren’s Resistance is than the foe’s. One point higher and he gains an automatic follow-up attack, five points higher allows him to negate the counterattacks of melee foes, and ten points allows him to cut the foe’s non-special damage reduction in half.
• Stacking more Resistance is a good option for Soren, but he’ll also want additional Speed in order to win Speed checks against slower foes with follow-up negation skills, making skills such as Blade Session a good option for Soren’s sacred seal slot. 
• Soren’s best B slot skill is Lull Spd/Res due to both improving his damage output and making it more difficult for the foe to counter his weapon’s effects by stacking Resistance. He can also opt for Mystic Boost to negate adaptive damage, which would otherwise pose a considerable threat to Soren as it allows foes to hit his low Defense stat. Watersweep is another option that lets him circumvent counterattacks from magic using foes, but it reverts his combat back to a Speed check due to negating his own automatic follow-up attacks.

Passive A: Atk/Res Unity / Mirror Stance 3

Passive B: Lull Atk/Res / Mystic Boost

Passive C: Pulse Smoke / Preference

Sacred Seal: Mystic Boost / Mirror Stance / Distant Def

• Soren also functions as a solid Enemy Phase mage counter, although he won’t be able to take advantage of his weapon’s effects as easily, as they’re mainly player phase based aside from the automatic follow-up attack.
• Atk/Res Unity is Soren’s best A slot option as it gives him a sizeable boost to Attack and Resistance as well as helping him combat debuffs. Mirror Stance 3 is a decent alternative if the Guard effect is preferred, however.
• A Lull skill is Soren’s preferred B slot skill as it increases his damage output and makes it more difficult for the foe to counteract his weapon via Resistance stacking. Mystic Boost can also be run in his B slot to free up his sacred seal, although using it as a seal is preferable.
• Besides Mystic Boost, enemy phase stat boosting sacred seals such as Mirror Stance and Distant Def are good options.
