//Note: Pendant in Lost Worlds does provide some limited access to other eras but does not open up checks//

A "check" is performed when the player goes through a dungeon, fights a boss, speaks to an NPC, or performs any other action that will grant them an item, a character, or other progress. Checks are typically done until the player enters "[[go_modes|Go Mode]]" at which point the focus of the run will switch to pursuing the end of the game.

====== Key Item Checks ======

These are actions you can complete to gather key items. A few are available from the start of the game. As you collect key items, they will fulfill requirements that open up more checks and other areas.

===== Snail Stop =====

**Era**: 1000 AD\\
Visit the Snail Stop (the cafe in Porre) and speak to the man behind the counter. He will offer to sell you a key item for 9900G.
  * 9900G required
  * **NOT AVAILABLE** in Lost Worlds

===== Carpenter's Wife =====

**Era**: 1000 AD\\
Go to the Choras Inn and speak to the carpenter, who is guzzling away. He'll tell you to borrow his tools from his wife. Find her in her home and she will give you a key item. As it requires no specific characters, items, boss battles, or even money, this is the one truly free check in Jets of Time.
  * No requirements
  * **NOT AVAILABLE** in Lost Worlds

===== Zenan Bridge =====

**Era**: 600 AD\\
Enter Zenan Bridge from the north and speak with the Knight Captain. Then, go to Guardia Castle and speak with the Cook.

The Cook will stop you on his way out and give you a key item and a Power Tab. You will then be taken to Zenan Bridge to complete several battles.
  * No requirements

Once you have Toma's Pop, take it to his grave on the West Cape of Choras in 1000 AD. Pour it on the grave and Toma's spirit will reveal the location of Giant's Claw in 600 AD. Travel there in the Epoch and complete the dungeon to receive a key item.
  * Requires Toma's Pop
  * **NOT AVAILABLE** in Lost Worlds

===== King's Trial =====

**ERA**: 600/1000 AD\\
With the Prism Shard in your inventory, visit Guardia Castle in 600 AD and speak to the King. He will promise to secure the shell as a national treasure. (**NOTE**: If you have begun the Zenan Bridge quest by talking to the Knight Captain at the bridge and the King isn't on his throne, go upstairs to the left and he will be in bed recovering. Speak to him there and he will secure the Rainbow Shell) Now travel to 1000 AD. With Marle in your party, go to the courtroom to start the King's Trial sequence. You will receive a key item in the basement before fighting a boss in the courtroom.

Defeat the boss on the left side of the basement, then catch the rat to learn the password to the right side (you must do this every playthrough regardless of if you remember the password).

  * Requires Future Access via Pendant/Trial quest

====== Character Checks ======

All recruitment points are based on where characters are recruited in the vanilla game, but note that Frog is recruited first in the Cathedral and later in the Burrow and Magus's recruitment spot on the North Cape in 12,000 BC will be empty. Most game modes follow the same logic, but Lost Worlds (in which you begin with Prehistory, Dark Ages, and Future open instead of Middle Ages and Present) differences are noted in the lists of requirements below each check.

Jets of Time gives you two characters to start. The other five characters may be recruited as follows:

===== Front of Cathedral =====

**Era**: 600 AD\\
Enter the Cathedral and pick up Queen Leene's hairpin from the floor (you can pick it up even if it is not shining, but if you aren't able to find it, speak to the nun in front of the organ to make it light up). Defeat the four Naga-ettes and a character will join you.
  * No requirements
  * **NOT AVAILABLE** in Lost Worlds.

===== Back of Cathedral =====

**Era**: 600 AD\\
Complete the Cathedral by defeating Yakra in the back room. You will then be returned to Guardia Castle. Go up the stairs on the right side behind the thrones and enter the bedroom where a character will appear.
  * No requirements
  * **NOT AVAILABLE** in Lost Worlds.

===== Dactyl Nest ======

**Era**: 65,000,000 BC\\
Once you have access to 65,000,000 BC, enter the Dactyl Nest. Make your way to the summit and you will encounter another character. You will be forced to enter at least one encounter, which can cause a lot of damage at low levels, so it's recommended to enter Dactyl Nest with a party of three to greatly reduce the chance of a Game Over. 
  * Requires Gate Key
  * If playing with locked characters, requires Dreamstone
  * **NO REQUIREMENTS** in Lost Worlds.

===== Proto Dome =====

**Era**: 2300 AD\\
Once you have access to 2300 AD, enter Proto Dome. Make your way to the back (you will be forced to fight the first set of robots) and touch the character there to recruit them. **IMPORTANT:** Due to issues with how the cutscene is programmed, Proto Dome is known to be buggy. It is highly recommended to save outside, go in, get the character, and leave. Do not open the menu, do not switch your party even when the screen pops up automatically, and do not use the enertron.
  * Requires Pendant
  * If playing with locked characters, Factory must be completed
  * **NO REQUIREMENTS** in Lost Worlds.

===== Frog's Burrow =====

**Era**: 600 AD\\
A character can be found in Frog's Burrow in the Cursed Woods. You can see who it is anytime once the game has begun. To recruit the character, bring them the reforged Masamune.
  * Requires Bent Sword, Bent Hilt
  * Requires the reforged Masamune
  * **NOT AVAILABLE** in Lost Worlds.

\\

====== Other Checks ======

===== Unlocking Future Access =====

**Era**: 1000 AD\\
Once you have found the Pendant, bring it to Guardia Castle and speak to Pierre (near the door to the left of the stairs). He will ask that you come for a trial for stealing the Pendant. Tell him "yes" to start the jailbreak sequence (in vanilla you are allowed to wait to be rescued; in Jets of Time you must break out of your cell). After defeating Dragon Tank, you'll have access to 2300 AD.

In addition, freeing Fritz from the guillotine during this sequence will allow you to visit his shop and get 10 free Mid Ethers, but only if Crono is in the party.
  * Requires Pendant

===== Factory =====

**Era**: 2300 AD\\
Complete the Factory to unlock access to the End of Time via the Gate in the back of Proto Dome. This is not considered as fast as gaining End of Time access via the Gate Key, but can be a boon when the Gate Key is particularly buried. Because it unlocks End of Time, access to 12,000 BC/Mt. Woe is also granted. It is unlikely - but not impossible - for the Factory to be a required part of a seed.
  * Requires Future access via Pendant

\\

====== Unlocking Magic ======

**Era:** End of Time\\
Many standard game modes require the player to visit Spekkio at the End of Time to unlock magic, as in the vanilla game. If magic is not unlocked, Crono, Marle, Lucca, and Frog will only learn 3 techniques and after that must visit Spekkio to be able to earn more TP and learn moves. If one of these characters doesn't already know their first 3 techs, a visit to Spekkio will automatically make them learn the techs. To unlock magic, simply visit Spekkio in his room at the End of Time with the desired characters. If you want another character to learn magic later, you will have to return with them in your party.
  * Requires End of Time access via Gate Key, Factory, or the gate in the cave in 12,000 BC
