Robotrek enables you to combine items with the
Invention Machine, following the rules below:
Two weapons of the same type and rank, combined, add their ranks.
Shot1 Lv1 + Shot1 Lv3 = Shot1 Lv4
Combining a lower rank weapon with a higher rank one usually adds 1 to the higher rank one.
Shot1 Lv3 + Shot2 Lv1 = Shot2 Lv2
Some weapons can be combined, resulting in a composite weapon with added levels.
Sword + Hammer = Axe
Hammer + Shot = Celtis
