I recently reached level 50 on my stalker, and I'm looking to set them up with a full set of Invention Enhancements. Unfortunately, Savage Melee + Radiation Armor is not a particularly common combination on any character, and doubly so on a Stalker which tends to prefer defense-focused sets.
I did find one example build in Croax's wonderful pinned post. Unfortunately, this build is from before some of the recent updates and makes a few choices different than I personally would have: it skips placate, it doesn't take a snipe power, and it does not go into tactics or any +ToHit beyond the potential build-up procs.
After a bit of work I've created my own modified version of the build that uses the new Psionic Mastery for the combination of Psi-Lance and Harmonic Mind as well as picking up Placate and Tactics. It gives up a bit of recharge, defense, and resistance compared to Croax's though I think it still reaches the same benchmarks. I'm not particularly good at builds though, so I worry I might have missed something obvious - could anybody take a look and give feedback?
