• Tainted Isaac's unlock for Ultra Greedier is the XVII - The Stars?. Typically, this card symbolizes a lack of faith and despair. This is probably a reference to the fact that Isaac is shown to view himself as evil, and believing his only escape out is to end his own life.

Bug! Sometimes items generated by TMTRAINER can bypass or reduce Tainted Isaac's item limit. Attempting to pick up a non-glitched item with a glitched item selected for replacement will add the normal item to Isaac's permanent inventory. Bug! Using Esau Jr. as Tainted Isaac can cause some items to bypass the item limit. One of the ways to do this is by having full inventory and a "quest" item (such as The Negative), and switch to and from Esau Jr repeatedly. After each switch, Tainted Isaac should replace at least one of his passive items. After a few switches, some item slots will appear to be empty or will depict the "quest" item(s). At that point, certain slots are bugged, and Tainted Isaac can take items, ignoring the limit if such a slot is selected.
