Neverwinter

Not yet a guide on how to do all the mechanics of this trial, but you do not need the master version for the achievement. A random queue full of noobs may be enough to forget this exists. It'll take 2 weeks of capping the mod's currency, or one buy of the mod boost pack that's 1500 zen.

Edit: it may be unlocked automatically in random trial queue. You may need to run a few trials for it to come up, but that will let you play it sooner.
