What one relic yields on average when you open it alone, counted from the 6 rewards we hold a price for out of 6 — 100.0% of everything that can drop from this table.
A fissure is a mission for up to four players. The squad figure assumes all four open this same relic and the squad settles on one of the four rewards drawn: every player is given that same reward, the best of the four, so the figure is per player rather than split between them.
