Breaching the Tomb
Complete the Legionfall Campaign with a Timerunner.
Breaching the Tomb is a Legionfall Campaign completion achievement earned by Timerunners that rewards +1 Infinite Knowledge.
Complete Class Order Hall Campaign
Complete your class Order Hall campaign all the way through earning your class title before attempting this achievement. Without this, Maiev will not offer the quest 'Champions of Legionfall', blocking all further progress. Check the achievement 'A Glorious Campaign' to confirm your Order Hall campaign is finished.
Avoid Skipping Order Hall Quests
Do not skip any early Order Hall quests — for example, skipping 'Slowing the Spread' on Monk can permanently block access to required zones in Remix, making the achievement impossible to complete on that character.
Pick Up Defending Broken Isles Quest
Grab the quest 'Defending Broken Isles' before starting a Legion Assault, as you need the quest active to receive credit. Legion Assaults are only available for 6 hours every 14-18 hours, so check the assault timer and pick up the quest before engaging.
Complete the Legion Assault
During the active Legion Assault window, work through the assault objectives. Note that in Remix, assaults are being completed by the server population within an hour or two of going live, well before the 6-hour window closes, so log in promptly when an assault is active.
Save Legion Commander Elites for Quest
Do not kill the Rare Elite Legion Commanders (marked as skulls on the map) until you have received the quest 'Take Out the Head...', which requires killing 3 Rare Elite commanders. Commanders killed before accepting this quest do not count toward it, and their respawn timers are long.
Tips
Legion Assaults go live every 14-18 hours and last up to 6 hours, but in Remix they are often completed by the server within 1-2 hours of starting — log in as soon as one becomes active to avoid missing the window.
Hold off killing skull-marked Legion Commander elites on the assault map until you have the quest 'Take Out the Head...' in your log, otherwise those kills will not count and you may wait over an hour for respawns.
