Flask of the Frost Wyrm

Note that Mixology also increases the bonus itself by 30% (its 162 SP for alchemists)

Alchemy's Mixology passive effect increases the duration of all flasks by 2 extra hours, therefore lasting 4 hours. This effect is only active if the alchemist uses a flask they themselves have the ability to make. Otherwise, they maintain the 2 hour duration on a flask they cannot make themselves.

Finally a flask that will directly increase the power of healing spells. Rejoice!
