As expected, map clearing feel bad in moments when spectres are waiting for cooldowns to end, leaving player very vulnerable. This is not the best map for them also, a tight layout like toxic sewer would be preferable. Also my gloves are not ideal for these spectres, i just used what i had, its preferable to use gems that scale both: lightning mortar spell and lightning orb.

On the other hand they shredded T16 deli boss with ease.
