Basically, a function that will return a boolean
In addition to the normal relic spawning system, if a relic with an ADVR.spawnRequirement is set to spawn, it also need to return true in the ADVR.spawnRequirement
This could allow you to make relics that require you have a set condition met in order to spawn
For example, you could make a relic that only spawns if you have a certain other relic (like upgrades to something like glass cannon or vial of blue blood), or really anything, but i don't have enough time to give more examples
#ADVR.spawnRequirement
dense coral
this is already a thing in Balatro modding, and it works really well imo
this could also make weapon specific relics actually viable to make (although they're still not the greatest idea)
digital orchid
it should be noted that curses have something like this already, yet they do nothing with it
dense coral
yea, just something like that for every relic
nice thing is that this should be incredibly easy to add as well
also, if a relic doesnt have an ADVR.spawnRequirement function at all, it should just always act as if it returned true
prevents breaking mods, and also makes you not have to remember to put one every time
