I have added the unique skill "Linkage" and changed the unique skills of Cain, Alva, and Robert to this one. Holders of this skill add 1/10 of the support effect to their Atk when receiving support.
It is like a pseudo triangle attack. Due to the recruitment conditions in this hack, Cain, Alva, and Robert are not always present as all three, so the effect is made to work regardless of who they receive support from.
The trio gives each other 20 support, and Selphina and Glade give them 10, so they can increase their Atk by up to 6. They now have a unique advantage when working as a group. However, this is in theory, I think that in practice it would be tedious and unwieldy to constantly be aware of the range of support effects and move them around.
