card mod

[BG-57]

Quezacotl can learn Card Mod (80 AP) but you have to teach it Card first (40 AP). Card Mod should then be a learnable skill (unless you filled all of its ability slots). Amnesia greens will clear space if you need it.

Card Mod you then appear as a skill in your party's menu.

I'm assuming you want an Adamantine? You know you can (SPOILER) mug BGH251F2 at Fisherman's Horizon for one as well

A real roundabout way to get an Adamantine is to refine 10 Orihalcons using Eden's GF Abl Med-RF (30 AP).
