1. I'm not able to skip dialog that fast like in the current WR run, it only skips one line per jump (playing version 1.0.3)

2. Is death abuse, 1.16 item duplication, and relog invincibility abuse allowed? If yes, there should also be a Glitchless category. Also then it should be retimed by IGT.

3. What's the (speedrunning related) difference between v. 1.0.3 and 1.0.1?

in the settings is an option skip cutscenes, item duplication is only possible in version 1.0.1 1.0.3 is the glitch less category If you read the discussion in riveros speedruning DC channel you'd know that
