[One] notable feature of Dark Chronicle and Dark Cloud is the focus upon weapon growth instead of the traditional focus on character growth (in terms of statistics). When monsters are defeated, they drop Absorption Points (ABS), which, when collected, raise the experience of the weapon that dealt the final blow. When a weapon accumulates enough ABS, it will level up and gain Synthesis Points. Synthesis Points are used to infuse a weapon with an item that has been "spectrumized," which results in the weapon gaining specific stats depending upon the item(s) that were spectrumized. Almost every item in the game can be spectrumized and synthesized to weaponry. Weapons themselves can ... be spectrumized, but the resulting spectrumized weapon won't carry over much of its stats unless it's level 5 or higher.
