Support and utility characters are crucial for any successful Disgaea 6 party. Bieko naturally fills the healer role, but you can enhance her by giving her Evilities that boost healing power, SP regeneration, or provide defensive buffs to allies. Generic Clerics are also excellent healers. For utility, consider units with high movement to act as item throwers or Geo Panel manipulators. Thieves are invaluable for stealing rare items from enemies. Units with Evilities that provide EXP or Mana boosts to adjacent allies are also highly recommended for efficient grinding. Don't underestimate the power of debuffers, who can lower enemy stats, making even the toughest bosses manageable. A well-rounded support team can turn the tide of any battle.
