Level a Male Warrior and a Male Martial Artist to level 5 to unlock the Thief. Though weak initially, they are essential for stealing high-rank gear and are required to unlock the powerful Majin class later.

The Item World is where you power up gear and hunt for (specialists).

Focus on 5–6 core characters (e.g., Laharl, Etna, a Healer, and a couple of Mages) to ensure they receive enough experience without excessive grinding.

When creating a new unit, choose the character you want to be the "Mentor" (e.g., Flonne) to create the "Pupil" (e.g., a Red Mage). Standing next to the Pupil in battle allows the Mentor to cast the Pupil's spells. Once the spell reaches level 1, the Mentor learns it permanently—this is the best way to give healers offensive magic.
