Symbology (紋章術, Monshou Jutsu, lit. Crest Techniques), also known as Heraldry or Runology, is a recurring ability in the Star Ocean series that consists on the summoning of paranormal effects inside the battlefield via the use of symbols. It is only available to a small number of playable characters, its power depending on the caster's Intelligence stat (INT/MAG) and, when used, costs Mental Points (MP). Symbology has a wide array of effects, such as dealing elemental damage to foes, healing allies or granting bonuses or ailments on characters and enemies.
Symbology, Volumes 1 & 2
Located within the library of the village elder of Marze, the first volume on Symbology states:
The effectiveness of Symbology spells can be increased through repeated use. Over time , a spell can be developed into a truly powerful form.
The second volume reads:
Hasten Speech and Concentration can considerably boost the skill of a symbologist. Hasten Speech can shorten incantation time; Concentration allows for uninterrupted incantations. Symbologists who have acquired these skills will find themselves at an advantage in any batle.
Although the population of Expel is familiar with symbology, its population has no knowledge of any healing symbols. Only Nedian characters can use healing symbology since Nede has had a deep connection with symbology for millenia.
Four symbologists are again available; they are:
Symbology has spread throughout the entire galaxy as of S.D. 772, and thus, most characters are able to use it. The main difference between potential casters is the proficiency to use it, as the INT stat differs vastly between characters.
