Beat the Seraphic Gate ten times

You must first have three mages each equipped with a staff that allows them to use great magic. Also, they should have Mystic Cross as their combo magic (Shadow Servant is also useful). Find a battle with four enemies (for example, at Asgard Hill). When the battle starts, have all three mages use Mystic Cross simultaneously until the combo meter goes to 100 (let Valkyrie attack if it did not go to 100 ). If done correctly, all three mages can use Celestial Star and allow 99 hits. The number of enemies also affect the number of hits. However, it cannot go more than 99.

When equipped with the Razor Shaft bow (and perhaps the Angel Slayer sword), Valkyrie gains the third and final form of her finisher. It consists of her normal attack combo, the three Holy Spears (where the level 1 finisher ends), the Mighty Spear that hits for two to five times normal damage (where the level 2 finisher ends), then a residual energy strike that does five to twenty times normal damage. Which weapons will do this depends on whether or not Valkyrie is wearing the Nibelungen Ring; try it with and without the ring.

Save your game before you end the Chapter 7. There is a possibility that Freya will give you the sword Gram. If not, reset the game and keep doing this until she gives it to you. Gram is the strongest sword in the game, except in the Seraphic Gate.

Play in hard mode, and collect the eight Lotus Gems there. Then play the Seraphic Gate. You have now the access to the locked green doors, which is the location of the secret items and characters.

To see a scene where Brahms and Lezard discuss their future plans, simply wait a couple of minutes after the credits are done rolling. I believe this may only be possible if you obtain the A Ending.

When in the Tower of Lezard Valeth, you can shorten the time the elevator moves from point A to B by opening and then closing the menu or map screens. You can avoid battling the monsters that ride the elevators by using this trick.

In Dark Tower of Zelva keep the Secrets of Resurrection artifact and then change it to an Orihalcon. Then, change the Orihalcon to get the Creation Jewel. Use this to obtain the Glare Sword, Icicle Sword, and Crimson Edge spear from Broken Armor, Book on Everlasting Life and Broken Spear respectively.

Save in the final save point in the game, before the final Boss. When you reset the game, there will be a new option called "Seraphic Gate." It is a bonus dungeon that is separate from the game.

Press L1 + R1 at the "Enix presents" screen to advance to the title screen.

When obtaining the Bark Of Dryaid in Nolsoft Swamp, keep it. Then, when obtaining the Transformation /Creation Gem, change it to get the "Dimension Slip" accessory.
