How to fast travel to Saw’s Clench Ripper Drill Site
Step 1
Open the world map and locate Carcadia Burn → Ruined Sumplands; look for the drill site icon labeled Saw’s Clench.
Step 2
Fast-travel to Judgement’s Lapse Silo or the nearest safehouse (Wildhorn’s Beard is commonly used when unlocked).
Step 3
From the fast-travel point, head north along the main trail...
...until the map marker or the pit arena becomes visible — the drill site is a large sunken arena.
Step 4
Enter the arena and clear the rippers and psychos that spawn.
Clearing the waves triggers the boss trio.
How to start the Saw’s Clench Ripper Drill Site (and replay it)
The event is triggered by entering the arena and surviving the scripted waves, as given above.
After the boss fight’s first completion, a Big Encore (Moxxi) station often appears nearby allowing instant re-challenges for farming. If the Big Encore isn’t immediately present, return to the safehouse or reload the area to reset the encounter.
Boss fight at Saw’s Clench Ripper Drill Site: How to handle the Rippa Roadbirds (combat tips)
Step 1
First things first, clear wave trash efficiently. Use area-of-effect and crowd-control abilities so the arena is not overwhelmed when the trio appears. Prioritize survivability during waves.
Step 2
When the trio spawns, isolate one boss at a time. Focus fire on the most aggressive flier (often Gruntabulous Vork) to reduce incoming aerial pressure and stagger their dive attacks.
Step 3
Exploit verticality and take cover. Duck behind arena geometry to bait dive attacks, then punish when bosses are grounded or recovering. High burst weapons and knockback effects work well when the birds land.
Step 4
Bring mobility and long-range options to the fight. Airborne bosses dislike steady DPS that can keep pace (snipers, high-fire-rate rifles), while launcher-style ordnance handles groups quickly; consider elemental ammo that matches the bosses’ weaknesses.
Step 5
If the trio overwhelms, retreat to a vendor/bench area in the arena to heal and re-position — repeating hit-and-run tactics is safer than trading slots for prolonged fights. (Keep an eye on the arena edge to avoid getting flanked.)
How to farm the Wombo Combo and other legendaries at Saw’s Clench
Step 1
Make sure you’ve unlocked the nearby safehouse / Moxxi machine (enables quick re-challenge).
Step 2
Run the drill site normally — clear waves, kill the Rippa Roadbirds, and check drops.
Step 3
If the Wombo Combo does not drop, use Moxxi’s Big Encore (spend cash) or the site’s respawn option to immediately replay the boss fight without long travel. Repeat until it drops.
Step 4
To speed the loop further, bring single-target high DPS + area clear weapon so waves die fast but boss windows still allow burst. Group play reduces time per run.
