Here's some things I learned grinding this out (and make no mistake, it *is* a grind). 1. [b]Hell is other people.[/b] This is mostly in reference to playing Collector and going for those Half-banked medals. You will get bs'd by invaders. Your teammates will see your collector aura and gank your motes anyway. You'll miss the last shot on a blocker you need for Locksmith. It will happen. Keep at it. 2. [b]From hardest to easiest: Collector, Reaper, Sentry, Invader.[/b] The medals for Collector and Reaper took me several nights. Invader I knocked out start to finish in 2.5 evenings. Here are tips for each, with the understanding that I am below average at best: [b]Collector[/b] steal, steal, and steal some more. The half-banked medals are the hardest part. Stacked blockers stealing your motes can sometimes work in your favor, as your target is 50 and pops on deposit, not half when the primeval spawns. You may have to play a bit like reaper to get your motes before your teammates do, and then blow your super clearing blockers if an invasion is imminent. Once you've finished giant summons, try 12 points in collector and pop a reaper synth instead of a collector synth and you can wreck HVT's and bosses for their motes. [b]Reaper[/b] Likely your only real work is HVT's and Massacre. I had best luck with Massacre as bottom tree void titan with doom fangs. The smaller maps are your friend. I earned Massacre at least once on each spawn of the Nessus map, but most at the drill spawn. Stack INT mods on your armor, get your super, get there first. The beach on the EDZ map also got me a few. Got maybe 1 on the Mars map at depot. They're a mess, don't bother. Focus on HVT's on these. [b]Sentry[/b] Jotunn is your friend. Makes short work of blockers and is decent vs invaders if you're a bad shot. Camp the bank, focus on blockers and everything else will fall into place. [b]Invader[/b] I'm a bad shot so sniper was out. Used Jotunn for fusion/shotty kills. Tried sleeper for a bit for snipe/linear kills but ammo was a huge issue, even with armor mods. Settled on Queenbreaker and Komodo. Hardest part was mote theft. Again smaller maps are your friend. Situation matters but I went with hunter/invis and using your super to make them scatter, then hide behind a pillar or friendly blocker while you steal, keeping it between you and the enemy. Also, killing enemy invaders gives you credit towards the triumph, and Xenophage is a monster. That's it! Only other hard part is getting the armor out of the Reckoning without getting bored or irritated. Might go back and gild my collections badge for all 3 classes but I've got a ton of other stuff I'd rather do first. Happy hunting!
