The Dual Set-Up System, abbreviated DSS in game, is a gameplay mechanic introduced in Circle of the Moon. The game's protagonist, Nathan Graves, can collect magical cards, and combine their effects for a variety of magical abilities, from changing his whip into different weapons to summoning creatures to attack.
To create a DSS effect, Nathan must possess at least one Action card and one Attribute card. They are dropped from specific enemies, and once obtained, are never lost or used up. DSS effects consume MP, some per use of the skill and some by the amount of time the skill is deployed.
