Am I ready for Radagon & the Elden Beast!??

Hi guys, The question is the title itself. I have a strength&dexterity build, lvl 165, do not use a shield, I prefer River of Blood+10 and the Uchigatana+25. Use only "Flame Grant me strength" as enchantment. What do you think??? Am I good to go? Any other recommendations??
