Man-at-Arms should refresh his Riposte status as soon as it wears off and your Arbalest should alternate between marking The Shambler and attacking to get the most damage out of your Bounty Hunter while your Occultist heals as needed. If you use the first party build just focus on raw damage. During the fight it will summon two minions to fight with it that can deal high amounts of stress damage while The Shambler can cause heavy bleed or blight on your party so the relevant healing items should be brought along.

Depending on the dungeon difficulty The Shambler will have 77/116/158HP. An alternative party would be Man-at-Arms, Abomination, Jester/Plague Doctor and an Occultist. If you are specifically going hunting for The Shambler I would recommend taking a party with the ability to reach both the front and back ranks with ease, I personally find Man-at-Arms, Bounty Hunter, Occultist & Arbalest to be a great combination for this as all of them can hit The Shambler wherever it sits. To fight the Shambler you need to use a torch on the altar and the fight will begin immediately. Ancestor's Scroll Ancestor's Tentacle Idol Ancestor's Map Ancestor's Candle Ancestor's Bottle The Shambler can be encountered by location a Shambler Alter curio piece which randomly spawns in any of the games dungeons. These trinkets are - Ancestor's Coat Ancestor's Handkercheif Ancestor's Lantern Ancestor's Mustache Cream Ancestor's Musket Ball Ancestor's Pen Ancestor's Pistol Ancestor's Portrait Ancestor's Signet Ring The other five trinkets are obtained by defeating a mini-boss enemy called The Shambler. These can be quite difficult and I find aiming for 90% room clears is much more manageable than doing 100% of room battles. Nine of the trinkets are given as rewards for completing a dungeon mission, so far I have only ever had them offered to me as a reward for completing Lv.5 Long missions. There are 14 Ancestor Trinkets in the game.
