After speeding up the rest of the party, Sera flies upwards to the ceiling of the cavern, taking care not to bump on the numerous decomposed bodies hanging from the chains attached to the stone above.
Steyven advances next, his breath burning down the front rank of Joana's unliving bodyguards, burning several to ashes.
Nina follows up, diving right inside the undead mob, skillfully feinting trough the dozens of rotten hands trying to grab or block her path, until she finally reaches the chain priestess. Joana is caught completely by surprise by the bold attack, and Nina's fist connects directly with her face. The tiny doll can feel it is harder than steel on contact. She still succeeds in shattering its left side, sending Joana flyng upwards! The room trembles a bit as Joana impacts the ceiling at great speed, before she falls back down togheter with some debris, the nearby undead hurrying to shield their mistress once more.
Bulwark closes in, conjuring a defensive bubble around Nina before striking at the pack of walking corpses in front of him, cuting a couple down with his axe before smashing another with his shield.
The ranks of the undead quite depleted, Imos manages to penetrate their minds:
"Obey Joana.
Serve Joana.
Obey Joana.
Serve Joana..." Having synchronized with his targets, Imos launches a flurry of spines, taking several more down, before launching a volley of mystic missiles at Joana. The magic projectiles however fail to properly lock on and end up exploding against some of her surrounding bodyguards.
Izuna blends in with the shadows and suddenly fist marks appear on some of outward undeads, before they too collapse into dust.
With its numbers considerably reduced, and most of the remaining undeads half-broken, the mob still holds togheter, and in the middle of them you can see Joana rise her arms with her hands hanging down. Her eyes start glowing with more intensity while the rest of the room seems to become even darker and colder.
Yyesss... Come closer... Suddenly, the piles of corpses closer to you start moving, and several of the corpses rise, forming new mobs! Smaller than Joana's own, but still dangerous looking.
Before you can react, the depleted mob at the center surges forward, trampling over the front party members before lashing out with a variety or rusted weapons, trying to overwhelm you with their numbers!
Joana herself grabs four of the chains attached to her arms with her hands, and violently rips them off. In a fluid movement, she flings the weapons in the air, and as they fly, the metal links sprout razor barbs. Joana twists her arms, and the flying chains twist in mid-air acordingly, striking at Nina and Imos with great speed and power. On contact, there's sudden bursts of purple energy that drain their vitality.
As the leader of a mob, Joana counts as having total cover when it's beneficial for her, so not even magic missile can single her out. Also, she won't take the extra damage from cleave that applies to the mob itself.
