Drowning

Drowning is considered an especial cause of death in Hearthlands.

While getting attacked by wildlife or another player implies hoops or even outright barriers before a permanent character death can be inflicted.

Drowning is handled more leniently than in Legacy, where dropping to 0% Stamina in Deep Water resulted in instant death - even any gear and items held were irrecoverable.

Even still, currently (in World 16.1) getting Knocked Out in Deep Water is basically a guaranteed death sentence. A character who is "swimming" can't perform any kind of "Fast Travel" -action. Breaking an unclaimed boat is also not a crime at all, even if an unconscious Hearthling is relying on it to not drown.

Wearing a Silver for the Ferryman does provide a rare "get-out-of-jail-for-free-card" albeit the exact mechanics of how it works aren't documented.
