Duplicates

Duplicates are replicas of the victims of Trin's unique magic. She creates the duplicates by converting someone's soul into a shell that she commands. The race of the target isn't an hindering factor, yet the target can't be too powerful and has to be in view.

The number of the copies that she can keep at the same time depends slightly of her relationship level with Simon. Specifically, she starts out with a maximum of 6 copies at the start of Aka's route, +1 if her relationship score is 30 or higher, and +1 more if her relationship is 50 or higher.

At certain points in the story she will be able to free up slots by releasing copies once they're no longer needed, allowing her to copy new people later on.

Jade Clerks
During Aka's path, Janine asks Aka to sabotage House Jade, so the party uses Trin to made the Jade clerks into sleeper cells. The more Jade clerks duplicates there are, the less mercenaries (aka enemy forces) that House Jade can send against the Doom King's army during the invasion of Yhilin. With the exception of the Aramite Jade Clerk, all the clerks are dismissed after House Jade is finished off.
