Tech

A Tech (also known as Technique) is a special move that the playable characters can do in and.

Techs in Chrono Trigger
Using a Tech costs a certain amount of "MP", with weaker Techs costing little MP and powerful Techs costing a large amount of MP.

To learn more Techs, the character has to earn more TP. For example, Crono can learn Cyclone when he has 5 TP. After speaking with Spekkio, the party can also learn more powerful, magic-based Techs.

Certain techniques are magical, meaning that they factor in a character's magic stat to determine how powerful they are (as well as other effects).

Double Techs
Double Techs require two characters to perform. Each Double Tech requires that the two characters know certain prerequisite Single Techs prior to learning. Double Techs are learned by having the two characters in the party and knowing the prerequisites at the end of a battle. Every character save Magus has Double Techs. Every pairing of the remaining six has three Double Techs they can perform. This makes for a total of 45 Double Techs. (6 characters, 6*5/2 = 15 pairings, 15 pairings * 3 techs = 45)

Triple Techs
Most Triple Techs require Crono to perform. This is due to Crono being the leader of the group for the majority of the game. After bringing him back using the Chrono Trigger, you can have someone else be leader, making the three-person group comprise others besides Crono. Certain groups can perform Triple Techs together, but require one of them to equip a special gemstone.

Techs in Chrono Cross
Characters in Chrono Cross have Techs also, which fall under the category of Elements. With a few minor exceptions, all characters have three Techs, which are generally acquired by reaching a pre-set growth level (star level) and possibly involving a story-based event. These Techs are automatically allocated to the character's Element Grid in the first slot of the 3rd-, 5th- or 7th-level Elements.
