DELETE THIS

DELETE THIS is challenge #45. The goal is to defeat ???. This challenge is unlocked by unlocking. During this challenge, all items are randomly generated by randomly combining effects from other items in the game. Item sprites and text are randomly generated as well, providing no information on what each item does.

In addition to gameplay changes, the theme of each area, its obstacles per area, and music are randomized. Some obstacle sprites are randomized even within a level and sometimes the music may be missing altogether. Occasionally, even the floor texture might glitch out, replacing it with a plain color.

Strategy

 * Try to get an active item that has a low charge or does something beneficial. Be warned, as items are randomly generated, active items could also just damage the player.
 * Item prices in shops can vary significantly, from as low as a single cent to as high as 99 cents.
 * Trinkets, Pills, Cards and Runes are unaffected by the randomization that TMTRAINER forces on other types of items; finding good trinkets such as Curved Horn or Cancer, as well as saving powerful cards such as for bad situations, can help give advantages despite your lower-than-usual stats.
 * Due to the inherent random nature of items, direct stat ups are very rare. As such, Bombs and gain increased utility during this challenge, as their relatively high damage is unaffected by randomization.
 * Once you have a reliable strategy, stop taking items, as some of their effects (replicating or mass spawning enemies) can end the run.
 * Try to finish the challenge as fast as possible, as a game crash is always randomly likely to happen from picking up just one item.

Trivia

 * This challenge does not have a name in the game's files at all, and is not merely hidden from the menu: it is defined by the number 45 as its ID and a zero-length character string for a name. For clarity, it is referred to by the name of the achievement that unlocks it.
 * The TMTRAINER randomization is a reference to an old randomizer mod that came out before Afterbirth+.
 * Unused enemies from Antibirth such as Nightwatch, Corpse Eater and Barfy can appear in this challenge, although it is very unlikely.
