The Lighthouse is a Nightmare Unique staff with no boss attached: it drops anywhere in Hell, most often from H8 up (rarer below that home difficulty, never above it), and nowhere else. Every copy is item level 110, and there 0.2% of what falls comes up Unique. It is built on Perfect Griefmender Staff — step 6 of the Griefmender Staff line, item level 80 and up.

It always rolls the same numbers: +30% Healing Power, +96 Ward, +58 Power, +26% Healing Power, +82 Ward, +42% Holy Damage, +34% Cooldown Recovery, +69% Ultimate Generation and +10% Spell Leech.

One Unique drop in 40 is a Mythical copy: the same item carrying 15–25% Mythical Energy that boosts every stat on it and can never be changed; the 15% floor is 10 times as common as the perfect 25%.

On top of that it carries The Lighthouse — Guiding Light's orb is 40% wider, mends 2 more allies and heals 30% harder, but casts 30% slower.

Wearing it hands you Guiding Light and Mending Chorus.

“It does not come to you. You steer by it.”
