In product development and process optimization, a requirement is a singular documented physical and functional need that a particular design, product or process must be able to perform. It is most commonly used in a formal sense in systems engineering, software engineering, or enterprise engineering.
Development [edit]. Sephiroth originally appears as an optional boss in the international version of Kingdom Hearts, and was retained for the Kingdom Hearts Final Mix version of the game, which also added a short scene between him and Cloud.n Kingdom Hearts II, he is also one of the hardest bosses, having no true rival, standing out as the game's hardest boss. Kingdom Hearts II Final Mix also has the Organization XIII rematches and data battles, along with the Lingering Will, all of which are fights that greatly dilute Sephiroth's notorious difficulty.
Crimson Hearts are usually located at the ends of the branches that split from the main circular room of a Crimson area, kept inside small rooms of Crimstone Blocks. In order to reach them the player may use explosives, a Nightmare Pickaxe, a Deathbringer Pickaxe, or better, Purification Powder. The first Crimson Heart broken also fulfills one of the two criteria for a Goblin Army to attack, which has a 1/15 chance of occurring on each subsequent day (you will also need to have at least one player that has 200 or more health in order for the Army to begin invading).
