Boy do I feel stupid. And somehow skilled at the same time.
Two things i didn't realize. 1) You can take out the antenna. 2) His armor is explosive resistant.
Here is what I did (on normal difficulty). I walked arround the center cone thing, firing explosives at his shield til it went down, then I slapped on force speed and pummeled him with explosives. Twice doing this and I was out of any and all explosive ammo. Ugh. Including thermal detonators, rockets, mines, and metal whatsamadoodles. Now here is the fun part. What I did after this is I circled around the outside until I had full health and force, put on force speed, ran up and did the medium style flip over/slash down move. Got bounced around a bit, and returned to circling. When his sheilds went down I slashed him. Took me 45+ minutes, and at the end of that level I had upwards of 150 uses of heal, and over 50 of speed. WHEE!!!
