Inferno

Yes — you may place a family member on a location even if it is already occupied by your or another player’s piece; however you must place in the quartiere matching the shield where you finished the Hell phase (or pay 2 Drachmas to place in any quartiere). (p.12)

A Soul must descend along the lines from its shield and, if the destination shield is occupied, it must continue down along the lines until it reaches an empty shield; a Soul never descends beyond its color level. To cross the Wall of Dis you must have previously placed a safe passage disc on that gate, and if no legal Soul move is possible (and you can’t pay to place one from the Graveyard) the game ends immediately (Sudden Death). (p.11)

You must already have a family member at the location and meet that location’s entry requirements; resolving an accusation you move the accuser to your Tower, return other family members from Florence to your home, place a matching Soul into the Graveyard (it has no owner), advance your Skull on the corresponding Sin Track and take the bonus, then move Dante and apply any Dante rewards. (pp.14–15)

Remove same-colored Souls from the Graveyard and return them to the reserve: 1 Soul lets you advance 1 level on any of the first four tracks, 2 Souls advance 1 level on any of the last four tracks, and 3 Souls advance 1 level on one of the first four and 1 level on one of the last four. If only one Soul is in the Graveyard you may only do the 1‑Soul River Styx and then immediately refill the Graveyard. (p.9)

Guardians can be moved to empty shields and then apply their specific effects to nearby Souls, but their effects never allow a Soul to descend beyond its color level; some Guardians (e.g., Minotaur, Cerberus) grant special movement or Wall-crossing abilities under their described conditions. Also, you may move a Guardian without activating its effect, but to use an effect you must move its standee to a different shield. (pp.22–23)

During final scoring you move each circle’s Phlegethon cube one space left for every empty shield in that circle (minimum value 1), then diplomas are scored by multiplying the Phlegethon cube value by the level of your Skull on that circle’s Sin Track. (pp.16–17)
