Greaves of Dendallen

While wearing these skeletal greaves, you gain a climbing speed equal to your walking speed and can stand on and move across any liquid surface as if it were solid ground. In addition, you can jump three times the normal distance, though you can’t jump farther than your remaining movement would allow.

Curse. When you first wear the greaves of Dendallen, you feel your legs suddenly ache. Make a DC 20 Constitution saving throw. On a success, you’re able to safely remove the greaves but are aware of the curse’s effects. On a failure, you take 6d8 necrotic damage as your legs fracture. This damage ignores resistance and immunity. Your legs stay broken but don’t hinder your movement so long as you continue to wear the greaves.

You can’t remove the greaves until they’re targeted by the remove curse spell. When you remove the greaves, your walking speed becomes 0. For every 24 hours that pass after removing the greaves, your walking speed increases by 5 feet, up to your normal maximum amount.
