One handed sword (Gravios if you don't have wifi to get Rune Blade) and Rune shield. If you max your level (which is very easy) and eat some vital gummi, you will take 1 from anything even with bosses.
In your choppy English, I think I understand what you're asking, or wanting.
Short Sword: Rune Blade or Gorgeous Sword Long Sword: Omni-Elemental Spear: Dragon's Fang Axe: Saint Axe Hammer: ??? (I haven't worked with hammers that much, yet) Rod: Rune Staff for usefulness, Magic Broom for INT boost
I regularly switch between the Rune Blade, Omni-Elemental, Dragon's Fang and Saint Axe. I also have a Rune Shield equipped along with Knight Boots and a Happy Ring. I'm level 78 and when I fought Fiersome all his attacks hit me for 1. --- I tend to answer pretty quick, so check back soon. When I'm here, I'm here for most of the day, so hang around and keep me company.
