The Target-cancel bug was the most game-changing bug, but has been fixed since the Dawn of Souls release. Gordon with 0 HP capable of fighting (NES). The remakes also add some bugs of their own: in the Dawn of Souls Whisperwind Cove dungeon, the Angel's Ring can never be obtained, as the map that is supposed to have it never appears. Most of the glitches are fixed in later remakes, apart from the critical hit bug, leading to the assumption it being a conscious choice by the programmers, and thus can no longer be viewed as a 'glitch'. This bug can also be exploited by granting the Monk/Master special armor properties but using the naturally higher defense of the unarmored Monk (e.g., leveling up with a Ribbon equipped and no weapon, to give the Monk the Ribbon's elemental and status protection but use the Monk's higher natural defense). This error can be fixed by viewing the armor screen from the pause menu. If they have no weapon equipped, but do have armor on, the game will mistakenly set their defense to their level, as if they were not equipping any armor. There exists a bug in the NES version, where upon level up, the game checks if the Monk/Master has a weapon equipped instead of their armor to determine what formula to use. Several weapons are also bugged in the NES version, in which the weapons' intended special effects do not take effect. The spells intended to raise effectiveness of physical attacks and evasion are glitched in the NES version, as is the item House, which saves the player's progress before it restores their spell charges. The critical hit bug has been retained through various remakes, but the Intelligence bug has been fixed in recent releases. The Intelligence stat is broken, meaning Red Mages are just as powerful spell-casters as White and Black Mages. As a result, physical attacks are substantially more powerful on average than they would have been had the correct critical rates been used.

The Intelligence bug and the critical hit bug are the most game-changing bugs.
