With that roll it looks like it was meant to be!
The water is freezing cold. Quintus takes Cold Damage: 1d6 ⇒ 4 from the cold water. However the ice also purifies his mind and gives him focus.
"One of the greatest resources utilized by the Wind Dukes were elemental weirds - strange beings of elemental energy that have potent gifts of prophecy and prescience. The weirds did not dispense their prophecies for free, and the Wind Dukes often had to bring mighty gifts and offerings to them when they fought the forces of Chaos."
"Icosiol formed a closed bond with one such oracle, a snow weird named Sionsiar. It was in large part due to her predictions and advice that Icosiol's exploits during the War of Chaos were so successful. Alas, the snow weird perished on one of the final battles, when desperate forces of Chaos launched an offensive against the weirds in attempt to cut the Wind Dukes off from their potent advice. Distraught by Sionsiar's death, Icosiol made arrangements to have her interred in his tomb in the chamber."
"Sionsiar's spirit will aid any agent of law who swims in her waters."
Quintus, you have a +4 to charisma for the next 24 hours. (same effects as Eagle's splendor spell and wouldn't stack.)
