Command nine summoned minions simultaneously.
Nine minions at once needs stacked summon capacity: Stardust armour (+5), a Necromantic Scroll and Papyrus Scarab, a Pygmy Necklace, a Bewitching Table's buff and a Summoning Potion get you there - then summon your nine. Endgame-summoner territory, but any class can borrow the gear for the minute it takes. Pops the moment the ninth minion materialises.
