Description
The Index is a place where players can see how many Logbooks for enemies they have gotten and how many maps they have triumphed.
Enemies

The enemies section can be used to see how many enemies the player has unlocked. By default, only a few enemies are shown here as locked, though in reality every single enemy in the game, including unused ones can appear here as long as they still exist in the game. Because of this, the Operation I.C.E Event enemies can appear here if their Logbooks are obtained, though they do not appear by default. Enemies that no longer appear anywhere in the game, such as the Tower Defense Simulator x PLS DONATE Event could actually appear here if their Logbooks were somehow obtained. Some enemies, like the Bolt or the Warden do not appear in the Index despite having their own Logbooks, most likely due to bugs.
This section will display information on the enemy. Every enemy will list its default health value, which is its health that will appear in a mode if it is not overriden by a mode specific health value and its speed. If either one of these is set to nothing, it will be displayed as "N/A". For some enemies, their description will also be included, which is the lore of the enemy. Next to the icon, the mode appearance will be displayed. On the side the enemy model walking will be shown.
Any enemies obtained through Logbooks can be spawned in the Sandbox mode, in multiple cases their legacy variants will be also unlocked, even if they do not appear in the Index.
Maps

The maps section can be used to see how many maps the player has triumphed. Unlike the enemies section, maps can actually be selected without unlocking them. On the side, the map name and icon will be displayed with a glow around the image based on its difficulty. Below that, the total number of triumphs, losses, the win and loss ratio, and the best time on the map will be displayed. Below that, every mode the map is playable on will be displayed. It will have a progress bar that fills up the further the player gets, reaching 100% on the final wave.
Triumphing any map (excluding event maps) unlocks it in the Index and gives the player the ability to use them in the Sandbox mode.
