Legend of Legaia (Japanese: レガイア伝説 Regaia Densetsu) or The Legaia in Japan is a role playing game released on March 17, 1999, created by Contrail and made for Playstation console, it features 3 young heroes who live in a world covered in mist and darkness. When a young man named Vahn's village is nearly destroyed by seru(monsters) driven mad by this mist, he sets out to rid the world of the mist entirely. During this adventure he will enlist the aid of two other warriors; Noa, a young girl orphaned by the mist, and raised by Terra, a friendly monster possessing a wolf; and Gala, a warrior monk whose monastery was also devastated by the mist. All three combine with beasts known as Ra-seru, and as such become immune to the effects of the mist.
The game features a different approach to the standard turn-based rpg format. While all the basic actions remain present, with the marked exception of a block feature which is instead a luck based automatic occurrence, the attack command led you into another menu where you could string together combinations of high/low or left/right attacks, which in the right combinations, became devastating "Arts." Replacing block was a command called "spirit" which would not only decrease damage by up to half and lead to more autoblocks, but also increased the number of slots you had for different directional attacks on your next turn. The number of attacks per turn also goes up slowly as you gain in level, eventually allowing you to perform secret,super, and miracle arts which dole out an increasing level of hurt.
As magical as some of these "arts" can be, times will come when you'll want to burn some MP, and this is accomplished through a summon based magic system. As you fight enemy seru, if you manage to kill one without dealing too much extraneous damage, you stand a chance of your Ra-Seru assimilating it into istelf. You can call on any seru you've assimilated with to come to your aid at the price of varying amounts of MP. As you call on the same Seru, their skill will level up, (from 1 to 9) and they will gain new attributes to their attacks or healing powers.
