With REPENTOGON, the vanilla HP variables can be omitted and fully replaced by our more advanced variables.

Variable-Name	Possible Values	Description
items	string	This now supports modded items by using the names of the items instead of the ids. Same format as in vanilla, a comma separated list of values
heartcontainers	int	The amount of empty heart containers the character should start with. 1 unit = 1/2 a heart
redhearts	int	The amount of red hearts the character should start with. 1 unit = 1/2 a heart
soulhearts	int	The amount of soul hearts the character should start with. 1 unit = 1/2 a heart
blackhearts	int	The amount of black hearts the character should start with. These do not replace soul hearts and are applied after soul hearts. 1 unit = 1/2 a heart
goldenhearts	int	The amount of golden hearts the character should start with. 1 unit = 1 golden heart
bonehearts	int	The amount of empty bone hearts the character should start with. 1 unit = 1 bone heart
eternalheart	int	If a character should start with an eternal heart. 1 = yes
brokenhearts	int	The amount of broken hearts the character should start with. 1 unit = 1 broken heart
rottenhearts	int	The amount of rotten hearts the character should start with. 1 unit = 1 rotten heart
healthtype	int	The health type the player should start with. The int corresponds to the HealthType enum.
healthlimit	int	A maximum amount of HP the character should be able to have. 1 unit = 1/2 heart
speedmodifier	float	An inherent offset to the speed stat the character should start with. Base this offset off of Isaac's stats.
firedelaymodifier	float	An inherent offset to the fire delay stat the character should start with. Base this offset off of Isaac's stats.
damagemodifier	float	An inherent offset to the damage stat the character should start with. Base this offset off of Isaac's stats.
rangemodifier	float	An inherent offset to the range stat the character should start with. Base this offset off of Isaac's stats.
shotspeedmodifier	float	An inherent offset to the shot speed stat the character should start with. Base this offset off of Isaac's stats.
luckmodifier	float	An inherent offset to the luck stat the character should start with. Base this offset off of Isaac's stats.
gigabombs	int	The amount of giga bombs the character should start with. These do not replace normal bombs.
completionparent	string	Used for characters that have shared completion marks with a preexistent character, like Dark Judas and Judas. The name of the parent character should be used for this attribute
nomarks	bool	if it has any value other than 'false', it will hide the completion marks for the given character
achievement	int or string	This is now respected on modded characters. For mods, it's best to define this as the name of the achievement (for example, achievement='TaintedPeter', TaintedPeter being the name attribute of the achievement). Characters with this tag should have a second frame in their characterportraits(alt).anm2 which should be the "locked" picture for the character. In addition, all stat/item layers on the main menu will be hidden and the Unlocked By layer will be visible. See the achievements XML section for more info.
modcostume	int	Set this to match the "id" attribute of a costume with type="none" defined in the same mod (in costumes2.xml) to have that costume permanantly applied to the character (including during the mineshaft chase sequence). You cannot set both this and the "costume" attribute for vanilla costumes at the same time.
