Find Bhima and Tulli in the Boiling Bluff region on Koboh. Save them from a Mogu and they’ll set up holotactics in an upstairs room at Pyloon’s Saloon. You’ll then need to defeat all eight opponents, with each requiring completion of a certain number of consecutive waves (two, three, or four waves). If you fail at any point, even on the last wave, you’ll have to restart the bout from scratch. If you’re struggling, go away and scan more enemies to bolster your deck of available units. Bear in mind you have a certain number of battle points for each wave, with any unused points carrying over to the next wave. Spend points wisely and set up the best strategy you can to ensure you defeat the enemies put before you.
