The short version

30-second read
  • Stab is her weakest defence. At +80 stab against +160 slash and +240 crush, Osmumten's fang leads, then a Ghrazi rapier or zaryte crossbow.
  • Note where Rockfall debris lands. Those piles are your cover for the next Rock Throw, which lands about 6 ticks after she throws.
  • Leave the salve amulet in the bank. It does nothing on Ba-Ba even though she is undead.
  • She pays the best raid points. Damage on Ba-Ba earns 2 points per hit point, the highest rate of any path boss.
01

Overview: Ba-Ba at a Glance

Ba-Ba is the baboon boss at the end of the Path of Apmeken in Tombs of Amascut. Keep Protect from Melee on (it blocks her melee completely), hit her with a stab weapon, and spend the fight dodging her specials: falling rocks, a thrown boulder you block by standing next to debris or a baboon, a shockwave slam, baboons that open sarcophagi, and rolling boulders at 66% and 33% HP.

Her lowest defence is stab, which is why Osmumten's fang is the standard weapon here. In the boulder phases, ranged attacks on the cracked boulder always hit their max.

Access Requirements

Ba-Ba is only fought inside Tombs of Amascut, which needs the quest Beneath Cursed Sands. There is no separate requirement for the Path of Apmeken.

Beneath Cursed Sands is the only gate. The boss requirements checklist lists every other raid's.

03

Location and How to Get There

Ba-Ba closes the Path of Apmeken. Before her you fight eight waves of baboons while handling Apmeken's Sight calls: repair roof supports with a hammer, neutralise vents, and group up to cleanse corruption. Volatile baboons explode in a 3x3, and shamans are worth killing first.

Ba-Ba was a baboon matriarch who took Amascut's offer of immortality and was used to overpower Apmeken.

05

Inventory and Supplies

  • Your stab weapon plus a crossbow or bow switch.
  • Saradomin brews and super restores; Ba-Ba's max hit is 24 before raid level scaling.
  • A super combat potion. If Ba-Ba is your first path, the wiki suggests a divine super combat and an overheal before entering.
  • No cannon: Ba-Ba is immune, and thralls do work here.

Mechanics: Boulders, Rocks and Sarcophagi

Table 3Ba-Ba's specials and the right response5 rows
MechanicWhat it doesCorrect response
RockfallA rock falls on each player's tile, plus two piles of debris land. Heavy damage if you are under a shadow.Step off the shadow. Debris has 10 HP solo and more in bigger teams.
Rock ThrowShe throws a boulder at every player, landing about 6 ticks later for massive damage.Stand next to debris, an unopened sarcophagus or a baboon. Any of them blocks the hit completely.
ShockwaveShe faces one of eight directions and slams the shadowed area. Also used as a stomp if you stand under her too long.Move out of the shadow before it lands.
Baboon's DischargeUp to four level 77 baboons with 10 HP, more in bigger teams. One will try to break open a sarcophagus.Kill them; every hit on them is a max hit. An open sarcophagus fires energy in a cone.
Rolling StonesAt 66% and 33% HP she screams, knocks everyone to the bottom of the room and rolls boulders down the slope.Range the cracked boulder in each wave for a max hit. A boulder that hits you knocks you back four tiles.

Solo, each boulder has 25 HP, rising to 27 at path level 2 or 3 and 31 at path level 4+. She stops rolling them after ten sets, or early if you get past the boulders and hit her with melee.

07

Where Ba-Ba Sits in the Raid

The learning order the wiki suggests is Zebak, Kephri, Akkha, then Ba-Ba, so most players learn her last. Speed-focused teams flip it and take Ba-Ba first, since she and Kephri are melee fights and smelling salts are better saved for the ranged and magic bosses. The Tombs of Amascut guide covers the full order.

08

Fight Strategy: Ba-Ba Step by Step

  1. 1

    Enter with Protect from Melee on and your stab weapon equipped.

    She targets the first player in, then the player with the lowest current HP.

  2. 2

    After every Rockfall, note where the debris landed.

    That is your cover for the next Rock Throw.

  3. 3

    When she throws, stand next to debris, an unopened sarcophagus or a baboon until the boulder lands.

  4. 4

    Kill baboons as they appear, especially the one heading for a sarcophagus.

  5. 5

    At 66%, get ready for the scream.

    Switch to ranged and shoot the cracked boulder in each wave.

  6. 6

    Repeat at 33%, then finish her with your stab weapon.

Drops and What Ba-Ba Is Worth

Ba-Ba always drops Apmeken's capture, and the top damage dealer gets a big banana, which you give to Awowogei as part of the ancient key steps after the Into the Tombs miniquest. Damage on Ba-Ba earns 2 raid points per hit point, the best rate of any path boss.

10

Combat Achievements and Perfect Ba-Ba

Perfect Ba-Ba is a Master tier task for a group of two or more at raid level 150+, with every Ba-Ba invocation on. Nobody may take damage from her attacks off-prayer, her slam, rolling boulders, the rubble attack or falling rocks, and no sarcophagus may be opened. You can retry it by wiping, and banana peels do not fail it.

The Combat Achievements guide covers how the tiers unlock.

11

Ironman Notes

Group ironmen have one catch here: entering ToA with anyone outside the group costs the group its prestige. Ba-Ba leans on a stab weapon, so the first Osmumten's fang from the raid speeds this path up a lot.

12

Common Mistakes and Death Causes

  • Standing in the open when Rock Throw lands instead of next to debris or a baboon.
  • Letting a baboon break a sarcophagus open, which then fires energy across the arena.
  • Meleeing boulders instead of ranging the cracked one.
  • Standing in the middle columns before a threshold with Mind the Gap! on.
  • Staying under her long enough to trigger the stomp.

FAQ

What do I need to fight Ba-Ba?

Access to Tombs of Amascut, which needs Beneath Cursed Sands. Bring a stab weapon such as Osmumten's fang and a ranged switch.

Which protection prayer should I use at Ba-Ba?

Protect from Melee. It blocks her melee attacks completely. Her thrown boulder is avoided by standing next to debris, a sarcophagus or a baboon.

How do Ba-Ba's boulders work?

At 66% and 33% HP she knocks everyone down the slope and rolls waves of boulders. One per wave is cracked, and ranged attacks on it always max hit. Solo boulders have 25 HP at path level 0.

How hard does Ba-Ba hit?

Her max hit is 24 with 380 hitpoints, before raid level scaling. Rock Throw hits far harder if you do not block it.

What is Perfect Ba-Ba?

A Master Combat Achievement: kill Ba-Ba in a group of two or more at raid level 150+ with all Ba-Ba invocations, taking no avoidable damage and letting no sarcophagus open.

14 · Bottom line

Bottom Line

Ba-Ba is a positioning fight with a melee boss attached. Pray melee, keep track of the debris for Rock Throw, kill baboons before they reach a sarcophagus, and range the cracked boulders.

Perfect Ba-Ba needs every Ba-Ba invocation and a group of two or more, so it takes a team that already knows the room. If you would rather skip that, our ToA raid service is played with a person at the keyboard, no scripts. The other raid bosses are in the bosses list.
