The Cautious Slug is a new item in Risk of Rain 2.
It increases the player's base health regeneration by 3hp/s (+3 hp/s after avoiding damage for 5 or more seconds. Attacking will not cancel the effect as with Red Whip. The regeneration bonus will be active until the player takes damage.
- As is stated in the text, the heal is regarded as passive regeneration. It's still possible to achieve Naturopath with this equipment.
- This item is unaffected by Corpsebloom.
- In the Hidden Realms update, this item no longer gives a regen multiplier but instead a flat regen boost.
-  The logbook currently claims this item provides 4 hp/s (+4 hp/s). This is not true.
