You don't really need 6A on Fitness if you only want to reduce the Rage requirement: His sprint heavy melee is a bit buggy in that one kill with this will trigger Rage even if you have only one point in Rage.
You should decide whether to take more crowd control (Electric Hammer) or higher (single target) damage (Biotic Hammer).
I take Geth Scanner for more awareness.
Also: This might help you.
EDIT: Try to stay in Rage mode, so finish of enemies with sprint heavy melee when ever possible and save (Heavy melee with an active charge (Electric/Biotic) might not trigger it, since the power part of the attack might get the kill.)
Thanks for the tips. So here's some questions regarding melee. The sprint melee... how do you even do it? Run, hold the melee button, release it when connecting with target? Seriously, I only played like three games with krogan before, I have no idea how that works.
Also, on hammer charges. What expends them? Using the power after charging the hammer, or every melee attack? Every heavy melee? Something altogether different?
I just knew somebody would went there
Good thing to know some things never change.
Mordokai is an Asari. No shame there...
Now I'm imagining how the relationship between Valkyrie and Krolord would work out...
Flashy, that much is certain
And they both come protected, so no worries there.
I initially did not like this character at all, but lately I´ve had some fun using a 66066 double charge biotic hammer only build with Martial Biotic Amp V, AM3 and Strength Enhancer 3. My Omni-Blade holder of choice is usually the HVB Wraith on the Warlord (on this character I almost never shoot my gun as I just like smashing and slapping stuff around with him). If you just abuse the weight glitch with such a setup (not that you would actually really need to), the nominal BH cooldown is in the 5-6 seconds range (plus TA penalty).
In Rage mode every basic trooper unit should go down to a single running heavy melee (on Gold), a key is to keep rage going at all times. Sturdier small units such as Dragoons, Bombers, Possessed Captains, Pyros and Phantoms should nicely succumb to a single Biotic Hammer smash. Most bosses will bite the dust after a maximum of 3-4 triple melee BH combos. Your low CD effectively means that your hammer charge can be up at all times.
IIrc all that will still be true (on Gold difficulty) even if you spec his fitness for max health regen (which basically makes him immortal in rage mode except for sync-kills). AM3 helps a lot to get up close quickly. If (as opposed to me) you´re actually going to shoot your powerful gun, you´ll probably kill stuff even faster.
I'm not fond of Raider, though I blame this on my inability to use it properly. Very heavy, very inaccurate... sure, it packs a punch, but I don't know...
Also, here's a question that's been bothering me for some time now... does the protection from TA apply to health, shields or both?
