Your gold. Shows the game's value once the trainer has caught it (the game reads it when it shows or spends gold); a new value is written straight into it.

Your ritual recognition. Shows the game's value once the trainer has caught it: spend money on recognition once; a new value is written straight into it.

The ship's three attributes (combat, durability and mobility, in the order the game reads them), without their base part: the game shows each as this value plus the base. Press Capture, then open the ship page once. Only values whose base equals Expected base (6 by default; 3 on some runs) are caught, and Seen base shows the last base the trainer saw, so you can set Expected base to it and capture again. A new value is written straight into the attribute.

A hero's EXP. Type the hero's current EXP into Current EXP, press Capture, then open the bag and point at the EXP so the game shows it. Once caught, a new value is written straight into it.

A unit's energy in battle. Wait for the enemy turn to end, press Capture, then move a unit once: that unit's energy is caught and stays caught across battles. A new value is written straight into it.
