I read the whole spoiler while I had my morning coffee and I got curious too.

SELECT npc_types.id, npc_types.`name`
FROM `spawn2`
INNER JOIN spawnentry ON spawn2.spawngroupID = spawnentry.spawngroupID AND spawn2.zone = "lavastorm"
INNER JOIN npc_types ON npc_types.id = spawnentry.npcID AND npc_types.class = 2;

I ran this SQL on PEQ to get a list of cleric NPC's that spawn in lavastorm.

a_Solusek_goblin_priest
a_Solusek_goblin_priest
a_cinder_goblin_cleric
a_Solusek_goblin_priest
#Drexel
a_shadowed_man
a_shadowed_man

This is the list I came up with. The only interesting NPC is Dexel and he seems to have been added much later. So I am not sure ><
