Tabs are a somewhat-rare treasure found scattered about in Chrono Trigger. There are three types: Power, Magic, and Speed. While the tabs found in treasure chests in vanilla have been randomized (it is still possible to get tabs from chests, but not guaranteed), the ones found as “sparkles” on the ground will always be there, along with a few others. When fed to a player character, they permanently improve the base stat for that character. In vanilla each tab will always improve the stat by 1, but in Jets the Power and Magic tabs are randomized each seed. By default, Power Tabs will give between 2-4 points and Magic Tabs will give between 1-3 points. As of the 3.2 beta, these minimum and maximum values may be adjusted between 1-9.
Here are tabs listed by type and method of acquisition. Tabs that are not typically routed into Jets are italicized. Most tabs are acquired individually. Tabs that are “bundled” together are listed in their own section at the bottom of the page.
Power Tabs improve the character's base power stat by a minimum of 2 and a maximum of 4. This stat goes into calculations for physical attacks as well as physical Techs. Always remember that Lucca and Marle's physical attacks are based on their Hit stat, and there is NO BENEFIT giving Power Tabs to either character.

Magic Tabs improve the character's base magic stat by a minimum of 1 and a maximum of 3. This goes into calculating magical power for Techs. It is worth noting that restorative Techs benefit more from magic power than offensive ones. Any character may benefit from magic tabs (perhaps Ayla least of all, but even she has Kiss and Tail Spin), but healers tend to get more mileage from them.

Speed Tabs increase a character's speed by 1. Because the lowest base Speed in Jets of Time is 8 and the maximum value is 16, Speed Tabs aren't given a random buff. Many players consider them to be the most valuable tab type.
