Heart Lantern

The lantern drips a steady trickle of health back into every player standing inside a wide box around it. That sounds tiny until a boss fight runs six minutes, at which point it quietly undoes an entire attack you would otherwise have had to dodge.

Hang one in the middle of any arena you build, with a campfire underneath it and a shallow pool of honey to stand in when you need a moment. The three effects add on top of each other, and together they turn a fight of attrition into one you can survive by playing patiently.

• Keep a spare on the hotbar when exploring. Dropping one after a bad fight beats walking home.
• The radius is generous but it is not the whole screen. On a long rail arena, space several out rather than clustering them at spawn.
• Wiring one only flips the light on and off. The regeneration keeps running either way, so do not waste a switch trying to save the effect.
