SWTOR Mek-Sha Red Mastery Datacron Location Guide

The Red Mastery Datacron increases your aptitude in combat, allowing you to do more damage. It will grant you Mastery +7 to your permanent stats along with codex: Huttbreaker's Rebellion. There are 2 Datacrons in total located on the planet / asteroid of Mek-Sha.

Datacrons are collectables scattered around the galaxy in Star Wars: The Old Republic. Each Datacron contributes towards your Legacy's passive stats permanently. Furthermore, they also provide interesting Lore and Codex Entries about the Old Republic era.

Starting coordinates: 77, 3800.

The Datacron is located on a walkway far below the strip at Slugfall Cantina in the Slugfall Harbor map. This Datacron will have a few tough jumps, both in timing and the sheer length of the jumps, so I highly recommend Speeder Piloting V in your Legacy (require Legacy level 15 and Speeder Piloting IV - 1.8mill for both IV+V) for this. I struggled extremely without it.
You will start on the bridge towards Junker's Junction.

(For a cheese path, scroll to the bottom)

As a very colourful hologram kiosk approaches the bridge from the left and flies above it to the right, use a mount to jump on top of the kiosk as it returns over the bridge again going left.
Pro tip: Disable bloom in preferences, under the "Graphics" tab to not be blinded aboard the kiosk.

You will fly over 3 walkways, the first one being the one with the Datacron on, but do not jump off until you reach the third one with a dark blue shuttle parked at it. If you fly above another bridge, you've gone too far and you'll be kicked off. Jump to the shuttle well in advance, otherwise you will overshoot the jump massively.

From the dark shuttle, you have to jump to the next shuttle on the left parked at the next walkway. This is a far jump, and I really recommend Speeder Piloting V here.

From the second shuttle, climb onto the second walkway and run towards the container structure.

From the ledge, jump to the third shuttle and then onto the final walkway.

This will grant you Mastery +7 to your permanent stats along with the codex: Huttbreaker's Rebellion.

Prava's grasp on the station was tentative--the hollowed-out asteroid required more upkeep than a typical mining station, and despite its profits, few in the Cartel believed the small operation was a worthy venture. Without sufficient outside investment, even the most basic infrastructure was difficult for the Hutt to maintain.

During the Hutt Cartel's crisis on Makeb, Prava's attentions were more divided than usual, and a Nikto slave named Gritha Dar used the Hutt's distraction to her advantage. Captivating and eloquent, Dar persuaded smugglers, gun runners, ex-Mandalorian warriors, and even slave traders that doing business with her instead of a weak and incompetent Hutt would be far more lucrative.

Once she secured her network of resources, Dar rallied her fellow slaves against Prava and his mercenaries, who were blindsided by the overwhelming forces the slaves had acquired. Dar was a ferocious leader, and Prava was outmatched from the start; the revolution was over almost as quickly as it began.

When the dust settled, no one questioned that Dar should lead the survivors through whatever came next. Dar immediately accepted her new role, formed a council out of prominent figures who supported her rebellion, and renamed the station "Mek-Sha," in honor of a friend she claims inspired her revolution.
