ASHMARCH

Bosses

The 2006-era bosses in their original form — King Black Dragon, Kalphite Queen, Chaos Elemental — alongside later encounters rebuilt inside the same client: General Graardor, Kree'arra, Commander Zilyana, K'ril Tsutsaroth, Zulrah, Cerberus, the Corporeal Beast, Demonic Gorillas, Revenants and Wintertodt.

Ashmarch runs the 2006 client, but the boss roster is not limited to what existed in 2006. The 2006-era bosses are here in their original form, and the later encounters have been rebuilt inside the same client rather than bolted onto a newer one.

Most of these hit hard enough that food alone will not carry you. Check the recommended protection prayer before travelling, and bring a way out.

2006-era bosses

BossWhereNotes
King Black DragonDeep Wilderness lairDragonfire protection is mandatory. Drops dragon items and the KBD heads.
Kalphite QueenKalphite Lair, Shantay PassTwo forms, and the second changes attack style. Bring gear for both.
TzTok-JadFight Caves, Karamja62 waves, then Jad. Prayer switching on his attack animation is the whole fight.
Chaos ElementalDeep WildernessDisarms and teleports you mid-fight. Never bring anything you cannot lose.
Barrows BrothersMorytania cryptsSix brothers, then the tunnels. Rewards scale with how many you kill.

God Wars Dungeon

All four generals are implemented, each behind its own killcount requirement and each with three minions that must be handled before the general becomes manageable.

GeneralGodStyleNotes
General GraardorBandosMelee / RangedHits through Protect from Melee. The most forgiving of the four.
Kree'arraArmadylRanged / MagicRanged only - you cannot reach him in melee.
Commander ZilyanaSaradominMelee / MagicFast and accurate. The hardest of the four to solo.
K'ril TsutsarothZamorakMelee / MagicHis special ignores prayer, so bring more food than you think.

Later encounters

BossStyleWhat makes it different
ZulrahRanged / MagicRotates between phases, each demanding a different prayer and gear switch. Learn the rotations before bringing good gear.
CerberusMelee / allSummons three souls that must be prayed against individually. A Slayer task requirement.
Corporeal BeastMelee / MagicHuge health pool and drains stats. Built for teams; solo attempts are long and expensive.
Demonic GorillasMelee / Ranged / MagicSwitch protection prayers as they switch style. Punishes autopilot harder than anything else on this list.
RevenantsMagic / allWilderness only. They heal off you and skull you. Risk exactly what you can afford to lose.

Wintertodt

Not a conventional boss - there is nothing to attack. Wintertodt is a Firemaking encounter where a group feeds braziers while the cold damages everyone in the arena. Rewards scale with the damage you contribute, and it is one of the faster routes to a high Firemaking level.

Anything killed in the Wilderness - Revenants, the Chaos Elemental, the King Black Dragon - can be attacked by other players while you fight. Assume you will be, and gear accordingly.
