Explanation: As a user of a single weapon, namely the swallow (two-blade sword), Kensai Magus fits Serge well because he also uses it as a spear. He later moves into Eldritch Knight for BAB+ and spell benefits, but takes no Arcane Armor feats since Kensai provides the dodge bonus he needs. His spell selection is not ideal but covers most of the simplistic bases of the Chrono Cross elements. Sanctified Spell (a 3rd Party spell) allows him to deal holy damage with arcane spells, reflecting his White Element. Phantasmal Killer represents Hellbound/Hellsoul, which can kill in one hit without damage but often fails. Cavalier and Battle Herald serve to augment his tactical abilities for the Double and Triple Techs.

His own techs can be represented by Bladed Dash (Dash ní Slash), and the Sanctified Spells mean that Luminaire and Flying Arrow can be represented with the appropriate spell converted to holy damage. Being an Islander, River Fighter lets him charge downstream while swimming while Explorer gives him bonuses in the water. The rules donít allow for a weapon to exceed a +5 bonus, so it has a +1 bane bonus against five of the enemy types that the Mastermune does extra damage against in the game - the ones with equivalents in Pathfinder.

His Stealth represents his ability to evade enemies on the over world with ease (he also infiltrated Viper Manor). Profession (Sailor) is obvious since he can travel by ship and does this quite a bit. He must be somewhat convincing with his arguments as well, since random strangers have a habit of following him within minutes of meeting, hence his Diplomacy/Bluff/Intimidate

Itís hard to judge Sergeís motivations since heís a silent protagonist, but heís probably Neutral Good, since he doesnít represent any ideology beyond ďsave my friends and/or the world and OH MY GOD WHAT IS HAPPENING TO MY LIFE,Ē but is clearly willing to risk his neck for pretty, bratty, mildly abusive strangers (I.E. Kid). Also, heís White element - the other White-innate characters are either explicitly divinely-empowered (Steena), a healer-type (Doc + Riddel), or an innocent child (Starky), so White puts him in good company.

Charging allows him to simulate some of his techs and capitalize on his long-hafted weapon. There was no way to give Serge a near 100% critical (because the Mastermune does that), but the Kensai + Improved Critical means heís got a 20% chance to crit-threat on each attack (17-20 range), and five attacks a round (if greater two-weapon fighting); even more fun since he gets to cast a spell as a swift action when he crits.
