The Cleric's Apprentice

The Cleric's Apprentice is a level 6 side quest in Howling Woods — a compact rescue-and-retrieval story in seven objectives. You find the missing Apprentice in the woods and speak with them, but the conversation is interrupted by spiders: an arena fight clears the ambush, and you rescue the Apprentice from the aftermath. The second half is an errand with a twist — the Apprentice's satchel is missing, so you track it down, pick it up, and carry it back to Little Howl, where handing it over closes the quest.
The spider ambush is the only real combat spike, so bring area damage if your build is single-target heavy. The quest is short enough to fold into a Howling Woods farming loop without much overhead.
Rewards
First completion grants the full Mushroom armor set — Robe, Boots, Cap and Leggings. That makes this the dedicated source for the Mushroom family, worth one clear for any hero who wants those pieces for a mixed set (each armor piece carries its own unique effect, so even one or two pieces can slot into a build — see Armor). There is no boss encounter and no repeat-run rewards listed. You must finish Corruption in the Woods — Minecraft Dungeons II Quest Guide before this quest becomes available.
