(Bertrand has more Dmg than Jeanne but Jeanne has more Mp more Mag Def+atc+5 times transform+She is Cute)
Spear Fighter: No doubt----->> Gilles (All the way better than Jean)
Axe Fighter (Tank) : Fufus ofc. Most Hp,Most Attack power and Most Def in the game. All u have to do is give him a Mobility+2 or Mobility+3. After level 35 with mobility +1 u will find out how important he really is. at level 99 he has almost 1400 Hp with Hp+300. With Attack 700 u can almost kill everyone with 1 hit and Godspeed to the next target.
Thief: Colet. Colet has skill Four Hits. that really kills. He has more Attack+Hp than Rose. But rose has more Evade and magic Def. It;s all up to u which one u want to use. i prefer Colet.
Mage/Healer: Richard. Most Magic attack and Magic Def.
Bow Fighter: I prefer Marcel, More hp More Dmg done.
Gears u need for actually All chars u have.: Mobility+2/3, Three/Twee Rounds,Hp Recovery 3,Hp+150/300
(Why i take Mobility+? It makes the fight much faster. and if ur Ranger or Mage getting in range with enemie,it goes pretty have for them to survive excapt u have two healers around. With Mob+ u can always run away then use heal or just item to keep urself up)
Rest of the chars are not that interesting. I have leveled them all to level 99.
Best way that i leveled rest of my chars From 50-99:
After Voldor Temple is opened. I take my Main Tank Rufus to tank the dragon. Give him Dragon Slayer,Hp recovery 3,Hp+150. Healing wind 2. Let him tank the dragon and ofc also dps the dragon. Leave the rest of ur 4 chars on the otherside of dragon and dont forget to give them also Hp recover 3, Exp Bonus 4 and Frame or other Area skill. Exp Bonus 2 can be farmed in Chalon. 4 of it can make a Exp bonus 4. Thats it.
Sorry for my english. And all i wrote are just my opinions. I just hope this will help some Jean D arc Funs.
Dunno about you guys but I use Jean instead of Gilles. Maybe it's just preference. I really don't use transformations that much so I don't really care if the character I'm using is an armlet wielder or not. Peace.
