I picked up an Adaptive Curing scroll for my Empath at HotRF and it doesn't seem to make the Flush Poison spell linger even though it is specified as an effected spell in the ADC spell description.
It works as intended with Cure Disease and Heal.
>Adaptive Curing is not an independent spell, but an extension of the Heal, Cure Disease and Flush Poisons patterns. With this knowledge, an Empath can cast these spells as reactive wards that linger, rather than waiting to perform a curing afterward.
