Yeah, the first fight with the two soldiers brings me from level 1 to 3.
The enemies that do over 100 damage are the blue dog enemies with the tentacles. If they bite, it only does about 35-45 damage. If they use their tentacle, about 95-125. They actually appear in the area you mentioned before you get Barret.
I find I do the best when I try to run as fast as I can and use spells exclusively for attacks using potions between all encounters. I can reach the Scorpion guardian that way, but between his stop-causing scanner and really powerful attacks, I don't stand a chance.
I honestly don't know if something got borked, or if my approach is all wrong - both are very possible. A couple of questions might help me figure this out:
Is it expected that I'll reach one or two limit breakers in EVERY battle (because I do) and they can't kill anything in one hit?
Secondly, is there anything in the BFE.exe for bootleg I could have enabled that would have messed with Hardcore mode?
As a side note, I've been trying out "reasonable difficulty" and I haven't made it far with it, but it seems very similar to vanilla--I just hold down attack and the game plays for me :\.
EDIT: I tried downloading and installing the latest version of Hardcore, and it seemed to temper some of the enemies' freakish damage. Most enemies do 30-40 damage, but those dogs don't do over 100 anymore.
Kuugen, I think I understand your advice now. The dogs (who still have wayyy to much HP) do not appear on the bridge to the reactor. What I did was immediately run inside and get Barret on my team, then run back out. The bridge only has soldiers and those green magic things, which are easy to kill in a few hits and they drop potions and ethers. My strategy is to now grind like hell in this area until around lvl 10 or so and then I'll have lots of potions and ethers to take on the inside of the reactor and hopefully not get killed too fast.
