Zill O'll

From Koei Tecmo Wiki

Zill O'll (ジルオール) is a 3D role-playing video game and one of Koei's most successful IPs for the genre. The game's appeal over other titles of its time is its free-scenario system. The game's title is an acronym for "Zillion of Wills". It hasn't been localized, although its action-RPG prequel has been shipped overseas.

The original Zill O'll was released again for the PlayStation 2 under the title Zill O'll ~infinite~. Aside from a graphical and audio overhaul and a few small changes, the original game remains largely intact. The PlayStation 2 version had a Premium Box edition which included a visual book, a calendar with 13 character illustrations, and 15 character post cards. The limited bonus for early consumers was a set of art cards.

The PSP re-release Zill O'll infinite plus includes several additions to differentiate itself from the original title.

Series character designs are done by Jun Suemi. Music for the original Zill O'll was done by Akihiko Teruta, Chinatsu Okuyasu, and Tsutomu Hirasawa. infinite music was composed by Hiromi Tazutani.


The plot takes place within the large Vyashion continent. Adventurers roam the land after the villainous Emperor Balor's fall, each aspiring to mimic the heroics of the legendary figure of their age. Serenity has returned to the people, yet the land is still littered with monsters and political turmoil. A prophecy unknown to many is beginning to bear fruit, a prophecy which states the slumbering Dragon King of lore shall rise to end the world once the "infinite soul" is born.

The year is 1200. The start of a single adventurer's tale is about to begin.


The overall format follows a basic RPG system. Character strength is measured by levels, and levels can be increased by experience points. Skills can be learned from Skill points that the player has acquired. Each character has a Soul, or job class, which can be changed to the player's preferences with Soul points.

It's actively encouraged for the player to keep a single weapon and/or set of armor rather than purchase multiple armaments. Only consumable items are encouraged for repeated purchase as they can assist the main party during battles.

Equipment can be customized at a town's Blacksmith with steel shards the player finds in dungeons. These steel shards can re-shape the weapon's appearance, increase their attack power, or endow it with an status ailment. Armor can be changed increase their protective properties or to protect against ailments. Certain unique items cannot be customized. The main character's equipment changes their appearance in the game. While the main character can change their equipment and fighting style freely, the rest of the cast generally has set preferences.

If the player is low on gea (ギア, game's form of currency), they can try to quickly raise their funds in the Guild at Ancient. A treasure chest which doubles the gea put into it is found inside. The gambling begins at 100 and, if the player wins consecutively, it can be raised to a maximum of 102,400 gea. The mini-game begins with the player selecting a random number to indicate the difficulty of the chest's trap. Once a number has been selected, a white slider moves along a purple and blue gauge on the screen. The goal is to successfully stop the slider within the blue spots. The easiest trap to disarm is 1 while 6 is the hardest.

The player can direct their main party's movements in predetermined routes over a flat world map ala Final Fantasy Tactics. Travel is measured by a period of days. While time is chronicled for the player's convenience, there is no definitive timelimit for completing the game.


At the start of each game, the player is required to create their protagonist. The player character can have different traits and origin stories based on whatever the player chooses.

After the story's beginning sequence, the protagonist and their partner begin their lives as adventurers. The player is required to investigate a place called Felidae Manor. This is the place where the player can instantly change their party member and check their affinity ratings for the cast. Whatever experience, skill points, and Soul Points the player earns are automatically transferred to reserve party members in infinite.

Once the mandatory events are completed, the story is then split into two different categories: the main story or character events. The main story is chronicled for the player as "Historical Events" within the main menu. The main story centers on investigating the mysterious Weapons of Darkness and following Nemea's adventures.

Character events are triggered based on relationships the protagonist decides to build. The player can befriend, romance, or even kill characters if they prefer. The player is free to recruit and befriend whoever they see fit. There is a total of 24 different characters whom can be recruited into the main party in infinite, though the conditions for unlocking them depends on the player's actions and starting point. Relationships with major characters may also influence changes in the game's main scenario and ending.

The original Zill O'll has 24 different endings. infinite has a total of 48 different endings in the game, many of which can only be unlocked based on the protagonist's gender. infinite has a new game plus feature is included for players who beat the game once and save their data.


In order to progress with the story, the protagonist needs to build their reputation and stats by fulfilling quests. Each town within the world map has a Guild from which these quests can be accepted. Most importantly, completing quests is the only way to earn Soul points. A maximum of three quests can be accepted simultaneously.

Each quest has a numbered difficulty rating with 1 for beginners and 7 for a high-leveled party. A timelimit is placed on each quest for the player to fulfill. Regardless of their degree of challenge, each completed quest rewards the player with 1 Soul Point, experience, and gea. A given theme is listed for each inquiry, often being listed within their title.

  • Delivery (配達) - deliver goods, the easiest to complete. Visit the designated guild listed within the quest description.
  • Escort (護衛) - guide a NPC to their location. Monsters will be momentarily stronger in the paths closest to their destination. The original Zill O'll forced the NPC to fight battles; if they died in battle, the quest was an automatic failure. infinite removes this feature.
  • Discovery (探索) - search for a rare item within the designated dungeon. Once it is found, the player needs to bring it back to the guild master.
  • Slay (退治) - exterminate a monster within the dungeon listed in the quest description and report back to the guildmaster. Optional boss fights to test the main party.
  • Rescue (救出) - look for a missing person lost within a dungeon and escort them back to their home. The guildmaster will offer this quest if the player has raised enough reputation in the area.

Quests can unlock new dungeons on the world map and introduce the player to harder monsters. Treasure chests can be found within dungeons to grant rare treasure. Every chest has a trap, however, and only characters who meets the required dexterity rating can open it. The method of opening chests is the same as the gambling chest. If the player fails to disarm the trap, the main party will be punished by the chest's damaging trap.


Combat is completely turn based; the order of attack is determined by a character's Agility stat. Actions are selected in a menu driven layout. The protagonist can have a total of three characters assist him/her in battle. An extra slot is reserved for guest characters.

The chart lists the elemental properties within the game:

Element Strong against Weak against
Fire Water Wind
Water Earth Fire
Earth Wind Water
Wind Fire Earth
Holy All Darkness
Darkness All Holy

After each victory, characters can level up their Fire, Water, Earth, and Wind elemental stats. The higher level, the stronger their tolerance to the element. Their elemental proficiency also increases the strength of a character's elemental attacks.

The game has a "Fast Break" bonus system, which rewards the main party for quickly finishing battles within 5 turns. If a character is particularly quick, they may trigger a "Double" or "Triple Action". These events allow the particular character to perform another action within a single turn count. Double and Triple Actions are activated for every battle participant and enemy characters, meaning that it may prove hazardous for the main party to challenge higher level foes.

Random encounters do not exist throughout the game. The protagonist can see monsters on the field and may choose to avoid them, except for the battles triggered by sailing at sea. Story events may trigger a battle sequence for the protagonist.

If the player wishes to do so their avatar may fight in an Arena within the cities Liberdam or Rocen. The protagonist must first participate in the qualifying tournament and face 8 solo matches. Should they win every match, they may then enter the main tournament in August. The player wins gea if they are victorious.


For simplicity's sake and to shorten the length of the list, only the characters who affect the game's multiple endings with their relations with the protagonist are listed below. Characters with asterisks after their names are characters whose relationships exists only in infinite and infinite plus.
