I just killed 7 in 1 trip with melee and void off slayer task. Got 1 shark drop and had 2 mantas and half a z brew left when I booked it. Inventory consisted of 2 super melee pots, 4 z brews, 2 prayer pots, games neck, sgs and mantas. Didn't bring my own spade cuz there's a spawn at spectrals. Also I used only 1 prayer potion dose when praying melee+piety the entire time, which I didn't even have to use when looking back at it. Sgs specs were rather bad tbh, 2 or 3 0's. Kills were very quick, I'd say accuracy was ~70% with a max of ~56 with whip. I only risked elite void and a fire cape.
I then went back with mage. Used zuriel's and crystalized ele staff with ice and blood barrage. I have killed 6 and haven't used a single piece of food/prayer potion. Freezing them with ice barrage and praying magic decreased their damage output by a lot. They will barely hit you and blood barrage will heal everything off. Now I understand this method can be somewhat expensive but you can always switch the ele staff for a rod/zuriel's staff and just ice barrage + fc them. You will still take minimal damage and you should be able to kill them even quicker and still stay for a fairly long time. Especially when bringing a sgs for some extra heals. I brought 2 super magic, 6 sara brews, blood/death/soul/law runes, 1 prayer potion and 1 super melee potion, sgs and mantas. I risked ragefires, zuriels hood and bottom.
Everyone complaining about spectrals is just mad they can no longer kill them with ~100k risk.
