Every relic in Guildrun
Relics are the run wide effects in Guildrun. An item sits on one hero, but a relic changes the whole guild, which is why the relics you pick up early tend to decide what the rest of the run is built around.
There are more than 400 of them, from common banners up to legendary relics, plus the quest relics that ask you to inflict a number of Burn or trigger a number of Stalls before they pay out.
