Phoenix adept/vanguard tips please.

wait. they have shotgun passives evo???  edit: ah, you mean the weight reduction on 6a? don't use it mselefs, damage is a better choice imo. who cares about cooldowns anyway

I build adept like this and vanguard like this.

For the longest time, I used to skip Lash on the adept, then only went up to four ranks, so I could have more fitness. Then I realized I don't need more shields with him, since he can abuse wallbang for all that's worth and the option to yank shielded enemies across the map is worth more than couple of shields. Power amplifier, to milk Smash for all its worth. Switch PA for cyclonics if playing platinum.

Vanguard is flirting with Grim Reaper whole match long. I skip Lash on him, since I'm now of mentality "Whole six ranks or bust". Since he'll be charging and smashing a lot(and will thus be somewhat vulnerable), I prefer extra shields on him, I think for this guy, they actually make the difference. Protocol is usually something like charge-Smash(if you rolled favourably for extra power after charging)-charge again for BE. When you're down to armor, he can do an occasional fire explosion as well and it doesn't throw his rhytm off by much. He eats armor for breakfast and doesn't have much problems with other defenses. He's as high risk/high reward as it gets and not for the faint of heart, but oh so much fun and very effective. But do play him on host only, or it will drive you insane.

I can say both of these guys rank very highly for me... the only ones in front of them are asari and both fat turians, but after that, these two are the best. Very mechanically unusual and take some getting used to, but once you do get used to them, they can wreck some serious shit

Also, he's the only other Adept (besides the Justicar) that chain BEs back to back without having to re-prime a target.

Raider on Adept? Why gimp yourself like that?

You like shotguns. Use shotgun pistol. Talon, AP/Drill ammo, Power Amp and HDB.

66644 build, his melee is too good to not give it extra oomph.

AP/Drill doesn't interfere with Biotics, and if you are using Geth Scanner you can add bullets to your wallhax.

...

Vanguard - need lighter shotgun. Wraith, Smart Choke + OmniBlade. Also AP ammo, skip Lash. Bonus Power on Charge.

Since Smash primes/detonates in the same cast you can do also Singularity>Lash>Smash>Singularity Explosion for 4 BEs in three casts.

I get that; Singularity explosion works well when there's Atlases and other slow enemies clogging up tight corridors. That can be hard to do on bigger maps with more open areas.

Some very nice advice above, especially the part about full Lash points and the biotic effect on Smash.   I personally like to use Bonus Power on the Vanguard as you can use it to detonate multiple booms... 
mordokai , love u man, but why are u using pistol amps on shotguns and assault rifles? 

No (way(more)). Vanilla adept is a biotic beast, on both cqc and ranged enemies whereas Smashdept suffers big on open maps. Singularity detonation is mandatory on him, works almost always and leads to heavy damage especially on bosses. Oh and hes not using throw but shockwave which helps so much situational (don't imply its good as smash)

No misunderstanding, i like both of them phoenix'es. Going melee with em is funnier than most of the rest specialists characters!!!
