Tips for SP Vanguard?

Any other power/evolution suggestions?

Fyi: I believe Annihilation does not trigger Biocombos with Charge. At least, it never seemed to in ym playthrough.

I went with Charge/Nova/Singularity. Two AoE primers and one massive trigger.

6th rank evo was 75% cooldown reduction for Charge. Zap all around the map knocking everyone over and stripping shields, take down all the mooks with ease then focus on any major foes.

Combat passives are important. Melee Synergy and Martial Artist, Shotgun (I used Dhan with Shield restore, 25% shields every two shots) and Asari sword with massive damage boosts from one another.

N7 Armour and Vanguard profile, Fusion mod of Power cooldown reduction 50%, you're a teleporting bomb with almost zero cooldowns.

For large armoured foes, singularity primes them then you can Biosplode, Nova to re-prime, then evade evade Charge.

I use Charge (4b, 5b, 6b) Annihilation (4a, 5a, 6a) and shield-powered Lance (4b, 5b, 6b) together with the fusion mod (can't remember the name) that resets cooldowns after enemy kill.

It still won't trigger explosions. At least not for me. I've walked right up to enemies with annihilation field on, waited until they were primed then charged and no boom.

OT: I run Singularity, charge, Nova. I go with no cooldown evo on Nova because I'm old school novaguard. Singularity to prime, charge in to explode, Nova to cleanup, charge again. Dhan is my main weapon.

Forget annihilation and nova. Singularity and charge are a way to go. Some people take another detonator as third power, but I prefer backlash to hold on until Charge is ready again.

Charge, punch, Reopeat.

Seriously though, thats ninety percent of what you do, and you take all the passives that would help you do that better. Other powers I found usefull situationally are nova (of course, clear the area round ya) and depending on your flavor any ranged power that does some damage, and buys you some time. Throw is a good one here, I also messed with concussive shot on occassion.

Charge - Backlash - Lance - build for melee with an appropriate weapon. Hurricane, Piranha etc. Very satisfying and you can switch the melee weapon for variety. You can switch Lance for anything else you like better, if you wish.

I have great fun playing a vanguard/infiltrator hybrid:

Cloak
3 headshots from black widow within the 2 seconds of double damage - ideally
when enemies approach, slow them with singularity
charge in, detonate
a few sword strikes
if you find yourself disoriented and still shot at, cloak again
get in safe distance
repeat

Charge (100% shields), Nova as a combo primer and the kett plasma sword to set people afire.

I also use Backlash because it's very usefull against Kett enemies using plasma assault rifles.

Throw/Annihilation Field/Pull

Screw charge, show them who's boss by making them come to you! Restore shields, when you hit a fool, restore shields when you kill a fool, restore shields when you pull a fool. You have shield restoration for DAYS with the right passives, which are what really make it work.

Evolutions in throw aren't really important, Annhi is 4b(pull fools more often, a is also good, your choice)5a(fools take more damage),6a(Fools are shield batteries), pull is all b's, 4b(pull more fools at once)5b(sucker punch fools harder when you pull them),6b(see 6a above)

Now we have the important passives 5a in Barrier increases your shields by 40% if you have an active biotic effect, since we're using annihilation field.. it's always so yeah, it's good. In 6 i prefer b, a is ok if you barely ever die in the first place but b makes you immortal, it's a get out of jail free card.
Next is exploitation in Offensive Biotics, it increases the damage enemies take by 20% when affected by your field, which is almost always, this also stacks with the debuff from pull. Add some boosters like Biotic Warrior and whatever unfortunate fool you pull in is going to get a severe beating from your beating stick.

The pull melee combo with the passives and right weapon will pretty much garentee you a one shot at whatever you pull and that means full shields on demand. And with all these % debuffs and buffs we want a melee that hits as hard as possible, so Krogan Hammer or the Smurf Sword. Up to you but i'm partial to the sword.

In Containment everything is nice but not vital except 2, you want more power restoration since regening as much as you can will keep you going, you can also boost this in Team Support in the Tech tree. The tree also let's you deal more easily with shields so it helps us a lot, especially with throw(larger combo detonation damage) but it's not vital for the build. Until you get those passives tho a good way to deal with shields is to simply throw a fool at another fool. Preferably within your Annihilation Field since you get both fool impact damage and biotic combo damage going on.

Combat also has some nice passives for increasing your melee and survivability.

Beat the game on hardcore using Charge/Nova/Singularity Mostly.

Spec it to fit your needs. It was stupid easy to clear mobs and I barely took cover, the one passive I like is the saving barrier, just in case you screw up. it has a 10 sec cool down which is OP.

Once it was too easy to clear mobs I decided to get TurboCharge (crazy burst dmg) for battles that required me to stay put, or melt bosses.

Used it with Piranha Shotgun and Kett vark sword.
