Most every single fighter has to face crossroads in his/her DL career at some point. Is it worth the pain of training, of struggling in vain for a spot for so long, just to maybe lose and downgrade and be laughed at? Lynx... Lynx isn't one of those. While he has the body of Serge, working under the control of FATE, he's still his own person. And that person is a cruel fighter, who enjoys inflicting pain on others and mastered both elemental spells and physical strikes. A puny mage is just the right target to attain victory and reestablish himself with. Claus's impressive array of elemental blockers can't stop all of Lynx's attacks, and the mage has no chance to outlast the tough body Lynx currently controls. The deadly feline shall not waste his chance.
