The highest-risk PvM on the server: nine bosses, the rings, the Voidwaker pieces and the wards.
The Wilderness bosses are the highest-risk PvM on Ashmarch: every one of them can be interrupted by another player. The rings, the Voidwaker pieces and the Odium and Malediction ward shards all come from this list.
Getting there
All nine are on the teleport menu's Bosses tab, which asks for a second click before sending you into the Wilderness. Callisto, Venenatis, Vet'ion and Scorpia cost 20,000 coins; the Chaos Fanatic, Crazy archaeologist, Artio, Spindel and Calvar'ion cost 15,000.

Assume a player killer will arrive at the worst moment, and bring only what you can afford to lose. Read the Wilderness guide first.
Callisto, Venenatis, Vet'ion, Chaos Elemental and Scorpia are also on the Boss teleport token, and all nine on the Master donator ring. Krystilia can give these bosses as Wilderness Slayer tasks once you unlock them (500 Slayer points).
Mechanics
Every special has a 3-tick wind-up and hits within 5 tiles: when you see it start, move away.

Scorpia calls an offspring every 40 ticks (up to 4 at once), and below half health her guardians heal her 2 hitpoints a tick: kill them. Vet'ion and Calvar'ion rise again in a second form at half health.
Artio, Calvar'ion and Spindel are the smaller cousins of Callisto, Vet'ion and Venenatis. Only one player can fight each of them at a time. Callisto and Venenatis have the most hitpoints and take longest, so you are most likely to be caught there. The Chaos Fanatic and Crazy archaeologist are short kills and a good place to start.
Rewards
The Ring of the gods, Tyrannical ring and Treasonous ring drop from Vet'ion, Callisto and Venenatis. Every boss here can drop the long and curved bones.
Drop table
Taken straight from Ashmarch's own drop data. Rates are per kill on Regular mode with no drop-rate bonus.
