Eithne moves into position, able to 'hug' the ceiling to avoid the very long arms of the Wretches... but as she works her magic, she can't bring herself to use them on Mourne, the power of his Sanctuary is simply overpowering. She turns and unloads a fury filled holy blast at one of the Wretches, severely wounding it.
Having seen the devilish slashes the Plague Fiend unleashed on Remy and hearing Austin's warning, Troben reacts. His flashing blade strikes mercilessly, cutting the fiend down.
With Troben's physical form suddenly gone from view, the Wretch (1) steps forward and attacks the 'Troben' left behind, causing it to disappear under its painful assault. The second Wretch batters the raging Vrod with thundering strikes but the big orc practically ignores them.
With blood running down her side and a trickle on her lip, Remy nods to Troben then spins around to face the second Wretch directly and drives the Dragon Lance deep into it. A couple more quick strikes from Vrod, grinning happily as he retaliates, nearly kills the terrible creature.
Baldric drives his blade into the big beast before him, causing it to growl in pain as it returns the favor to the paladin.
Tiberion steps forward and lays his hand upon Baldric, and with a quick prayer to his god, closes some of his wounds. "Not me, you idiot! Save my niece!" Baldric shouts.
"NO!" Austin shouts as he sees Eithne turn away from Mourn. He realizes what has happened and, growling, launches another fireball into the mouth of the open passage in the south east, the flame licking at Troben, but so well placed that it engulfs the vile creature, Mourne. Mourne cries out, and the 'barrier' that had protected him fails him. The vile thing quickly cast Mirror Image again.
Austin casts fire ball just out of range of Troben but still getting Mourne who both fails his dex save and his concentration save.
Terrain: The room is filled with thick viscera, slippery especially considering the softness of the ground. Whenever you move, you must make a DC 10 +1 per five foot space moved DEX Save or slip and fall prone. How much you fail determines in which space you fall.
Sadly, each of your enemies has feet with claws that grip into the terrain, nullifying this effect for them.
Eithne is currently flying and unaffected.
