A xenosaga battle system was once requested, but I just want the Tech Skills. Tech skills are used by pressing certain keys to use a different skill and two of them lead to a different skill. You have a bar showing how many slots you can use for the skills, items, and guarding.
Items take up one slot, skills take up two each, and guarding takes two.
You gain four slots each turn, and have six maximum slots.
You can only use the combination of tech skills after the first two if you guard, use an item, or only use one tech skill the turn before.
Example in terms of RPG maker skills: You are able to press C to use fire, following you are able to press X for aqua, which would lead to aqua flame where you could press Z.
