Gameplay
Though similar in some ways to its immediate predecessor in the series, some notable changes to the gameplay were made. Four characters are now used during battles instead of eight, and the most powerful spells require cooperation between two different characters. Additionally, movement through the land now happens on an overland screen rather than on a map with pre-chosen destinations, and the player can now freely move within towns and cities.
Like in Growlanser II, a character's most notable piece of equipment is his/her Ring Weapon. Each Ring Weapon grants different stat bonuses and has three gem slots. Each gem slot has a level from 0 to 9. If the slot is level 0, no gem can be equipped there, but otherwise the slot can be equipped with a gem of the slot's level or lower. These gems can grant a variety of benefits, such as increasing the damage dealt by a character or decreasing the cost of casting spells.
