Castlevania II: Dracula's Curse (IC)

[J-H]

Ghussam waves goodbye to you as you elect to swim across the river. "I see you have some insight. It will serve you well. I would bid you safe travelers, polite mortals, but it would be an empty gesture to do so."

Although the area around the bridge is not turbulent and full of rapids, it is an area where the river is narrower, and thus deeper and faster. You don't simply need to swim across the river - you also need to swim quickly enough to not be swept downstream a ways.

Spoiler: Athletics checks

Show

DC 15 to avoid being swept 1 hex downstream, still landing on the side of the river you want to.
Vidrik (1d20+1)[5]
Sabian (1d20+7)[21]
Chloe (1d20-1)[17]
Cassandra (1d20-1)[2]
Mustafa (1d20+4)[24]

Vidrik & Cassandra are being swept downstream.
Mustafa, Sabian, and Chloe succeed on your checks. Do those of you who succeeded want to roll a 2nd time to aid Vidrik or Cassandra? If so and if you fail the DC 15 on this roll, you're also carried downstream by the current.
If the party is separated, you simply land in 2 different hexes and have to spend 2 hours getting back together.
