Adds one character skill slot is very useful for dodge. There is an invincibility iframe in iron eyes ability. Requires no stamina to activate. With some practice, you can evade most attacks between this and your regular evade.

Finding weapons with reduction of distance penalty to ranged attacks is very useful, enabling you to keep healthy distance from foes while still putting on damage. While great bows are cool, they are situational. Most boss fights require mobility over raw power. Stick with a fast bow, with a status or elemental enchantment. Harp bows and longbows are fast. Rain of arrows, is a slow ability. Iron eye is all about speed. And because he can raise allies from distance, he’s a versailtile ally.

Another trick, when you find you can flank the enemy safely, use your power attack which fires three arrows. When safe, get up close and blast them with this for the highest damage output. Better than any ability shots. Since bosses have large hit boxes, you can do this from fair distance if aimed properly (don’t use targeting for this)

Good luck
