The pair techniques of Digimon World 2003 (original European version): two digivolutions that, together,
do a technique neither has alone. Read from the game's Digimon table (each form's pair technique and partner).
How to use one: while a partner fights as one of the two forms, open Switch and pick
another partner that has the other form among its digivolutions: the pair's icon shows by it, and choosing that form
does the DNA technique instead of a plain switch. Both partners pay its MP; then the incoming one stays in.
A form only pairs with its own partner form, and the two must be on two different partners.
