New idea :
1. Dash with heavy type weapon guarantees 100% immune to any incoming damage and CC while ginkui and dagger both cannot.
2. Speed might increase dash distance, letting you to use border for a little moment after dashing, but this theory is not guaranteed since I haven't tested.
3. The way to make damage might move to border + fire incendiary on the ground, resulting that open wide become unnecessary. To make it work, 100% evadable heavy type weapon is in need that guarantee you to evade all incoming damage while dashing when enemy is getting closer inside of your fire incendiary range.
4. Might need more stamina, becuz as long as you are rolling with heavy weapon and enemy is in fire range, enemy will get only damaged.
