Sand Knife

Sand Knife is a late-game melee weapon that is crafted at a Tungsten Anvil. It is obtained only after deeper exploration, and while its base damage is relatively low, it makes up for that with a strong poison-focused effect that can wear down targets over time.

When used in combat, Sand Knife grants 3 resilience and 14% critical chance. Its standout feature is the poison damage it inflicts: hits apply a debuff that deals 500 poison damage over 5 seconds, making it especially useful against enemies that stay in melee range or survive long enough for the damage-over-time effect to matter. Because its direct damage is not its main advantage, it performs best when used to keep pressure on enemies rather than as a pure burst weapon.
