PG 17.0 ParrainCirce

Demotion chess: Any piece (not pawn) that sets foot on the 8th rank is 
immediately reborn as a pawn on the 2nd rank of the same file; promoting 
pawns are excempted during the promotion move.

Duellist chess: Once a unit has moved, it must continue moving turn 
after turn, as long as it has legal moves.

ParrainCirce: When captured, a piece is reborn on the square that has 
the same distance and direction from the capture square as the distance 
and direction between the departure and arrival square of the next move. 
E.g. : 1. d4 e5 2. dxe5 Qe7[+bPf4]
