I am not certain why people are having issues regarding the getting hit thing. There are a few ways to get entropy, and at first level, all it does is give +1 enhancement to AC.
You can spend a Resolve, which if you aren't getting hit, is not a big deal.
I chose the Boundary discipline, which allows me to once per combat, if attack misses or hits, but deals no damage, +1 Entropy at level 4.
I chose to try to break the class. 18 Con + 2 for personal enhancements for a 20 Con.
My Entropic Strike was 1d4 + 11 at 4th level (+5 from Cons, +4 from Weapon Specialization trait and +2 from Strength Mod). I paired this with a Tactical Pike and behold, I can deliver my Entropic Strike up to 10 feet from me.
I stood in the doorway and stopped things from getting close.
He one shot the boss when the Technomancer cast Supercharge Weapon and did max on normal dice for 15 and then additional 15 with Supercharge dice.
Party encounters security droid by way of rescued Space Goblin.
Here is what happened:
Goblin starts cussing and runs to the Android Mystic (he has been getting piggy back rides through the asteroid)
Mystic uses fire extinguisher to propel themselves back 25 fee to the entrance and lay down cover at the same time.
Ysoki soldier books from other side of the hall and lobs a sticky grenade.
Vesk Mechanic hears the commotion and also runs for the door.
Lashunta Operative tries to access the computer.
Next round the rest of the party is halfway back to the ship and the Lashunta, hearing the robot, dives under the desk.
Long story: Lashunta waits a full minute to determine patrol pattern and find out he has 3 rounds to try to access the computer before it gets back. The entire party is gone. After 3 minutes, the robot finally sees him hiding under the desk and fires. Operative then trick attacks, succeeds, then books it past the robot to get stunned. Meanwhile the party sends the Mystic and the Goblin back to recover his corpse.
Operative then spends last remaining Resolve Point, stands and then books it out into the darkness.
When asked why, Operative explained that he couldn't see to run back to the ship, so might as well try to access the computer before he dies...
