series, Suikoden II employs a unique character leveling system from most RPGs. There is a fixed amount of experience points needed to gain each level, and experience gained after battles is determined by the difference in levels between the party members and enemies. This allows for low-level characters to catch up to the levels of enemies at later points in the game quickly, and reduce the need for level grinding. Runes, the source of all magic in the world of Suikoden II, are handled the same as the original Suikoden. Characters have a certain number of spell usages per "spell level"; for instance, a character with four level 1 spell slots and a Fire Rune could cast "Flaming Arrows" (the level 1 Fire Rune spell) four times. Some specialized runes or skill-based runes have different rules, such as unlimited use or a single use per battle. Updates from the original Suikoden include a grid and unit based tactical battle system, the addition of a three rune slot system which allows for three different runes to be equipped at once, a party inventory system, a "dash" button that allowed the player to move around the screen quicker, and vast graphical improvement. Also notable is the inclusion of a variety of mini-games including one quite reminiscent of Iron Chef. A transfer of data from the prior game in the series enables returning characters to enter the fray with higher levels and improved weapons. References to the original Suikoden are also adapted accordingly for a greater feel in continuity. Following the original Suikoden, Suikoden II contains three different types of combat: Regular battles: Where the majority of combat takes place in the game, the turn-based battle system in Suikoden II is considered typical of JRPGs at the time, containing options for attack, magic (runes), items etc. The player can enter battles through random encounters on the world map and dungeons, or at specific points of the plot. The player may have a party of up to 6 characters in this battle type, against up to 6 enemies. If all six characters lose all their hit points and are thus incapacitated, it is game over and the player must restart (exceptions exist for certain plot battles in which winning is optional). This is the only type of combat where the player can gain experience, items or Potch (the currency of Suikoden II). Emphasis is
