Also you may want one abyssal in Greenhaven (despite possible resonance explosion) is because if crops are ruined because there is masquerading abyssal fucking women in orgies and on purpose collect resonance to blow it up and ruin harvest with that, Crow can locate is there abyssal in orgies (using 1m for 300 yard radius radar) or not or is ruined harvest result of blown up resonance.<br/><br/>At least easiest way for abyssal ruin harvest is to participate in greenhaven orgies and other 'fertility' activities and then churning with resonance go unleash it in form of blight and then wait it cooldown until repeat the trick. In highest setting the resonance can create shadowland with blight what I remember.<br/><br/>Also if this is not method, if there is even shadowland tainted mortal alchemist involved, he can sense the said shadowland mortal in the 300 yard range (as said tainted mortals count as creatures of death/darkness). He cannot pinpoint the location but knowing the person is in 300 yards is good than nothing. Plus if there is abyssal with combat skills then Crow can help with the combat.
