How do you scroll a 1h sword?

So since I can't make a decent 1h sword, should I back off from it and get a 2H Sword?

This is what you should have asked from the beginning.
Post your total equip stats/various facts so that we can consider:
- Your total %stat bonuses
- Your total WATK
- What you can afford

so as to make appropriate comparisons.
The addition of a shield adds 20atk for funded players. That, alone, makes up for the lack of SEVEN pink scrolls (in terms of WATK, I'm not counting damage multiplier). Kick in potentials from the shield and you have a fair chance to beat the 50%'d two hand sword with a 60%'d one hand plus a good godly shield.
