heavy boots

Iron boots that grant +2 max health and +7.0 weight. They make you fall faster, sink faster, and take less knockback.

They have 150 durability. Blessing cubes drop them at 2.5%, the living style plant can yield them, and they are used in fusion for golden boots.

The extra weight also affects the grapple hook: it pulls hooked vermin toward you faster, since pull strength scales with your weight relative to theirs. The same weight makes swimming harder — you sink faster in water.
