==Main Stat Availability==
A Relic has one randomly generated Main Stat, determined by the Relic type.
The chances of getting a Relic with a particular Main Stat appears to vary. (For example, there are four possible Main Stat possibilities for feet Relics. If these Main Stats were uniformly distributed, they would each have a 25% chance of occurring. However, user-compiled dataGlitch/Star Rail Data Gathering Discord (June 6, 2023). Relic Mainstat Public Sheet. indicates that Speed appears as the Main Stat in only ~10% of feet Relics.)

==Subsidiary Stat Availability==
The max level of a Relic is determined by rarity, as well as the amount of initial Sub Stats. Sub Stats can be generated, or enhanced, by leveling the Relic.
Rarity of Relic 	5-Star	4-Star	3-Star	2-Star
Max Level 	+15 	+12 	+9 	+6
Base Sub Stat Amount	4-3 	3-2 	2-1 	0
A randomly generated Sub Stat is added every 3 levels, up to a max of 4 Sub Stats. Once there are 4 Sub Stats, every 3 levels will instead enhance a random, already existing, Sub Stat.
This means that a 5-star relic with 4 initial Sub Stats will be able to enhance its Sub Stats up to 5 times, due to its max level being +15 and it enhancing a Sub Stat every 3 levels. Likewise, a 3-star relic with 1 initial Sub Stat will be unable to enhance any of its Sub Stats, due to its max level being +9 and it adding a Sub Stat every 3 levels.
Furthermore, a Relic cannot generate duplicate Sub Stats or ones which are the same type as the Main Stat. (e.g. a Head relic with a flat HP Main Stat cannot have a flat HP Sub Stat, but could have an HP% Sub Stat. It also would not be able to have two HP% Sub Stats. It could, however, have both flat ATK and ATK%.)
Substats are theorized to be selected in a similar way to Genshin Impact. Specifically, whenever a substat is to be selected, a weighted selection is made from the pool of substats that have not already been picked, with the following weights:Community Document: Honkai: Star Rail Drop Rate Statistics
Substat	HP	ATK	DEF	HP%	ATK%	DEF%	SPD	CRIT Rate %	CRIT DMG %	Effect Hit Rate	Effect RES	Break Effect
Weight 	10	10 	10 	10 	10 	10 	4 	6 	6 	8 	8 	8
The initial weights sum to 100, though this will be reduced as substats and possibly the mainstat are taken out of the pool.
==Subsidiary Stat Values==
The initial value and increase per enhancement for Sub Stats are randomly chosen from 3 possible tiers according to the values in the table below.
