Items

There are two typed of items, Runes, and Accessories. Every servant you have in your party should have both of these, they are a huge help as you can gain damage, lifeteal, regen, hp, dodge, crit change, crit damage, and attack speed. You can also level up your items increasing their level and upgrading their bonus, once an item is +5 you can evolve it with another +5 of the same item type (rune +rune) of the same *rank* to create a random one higher *rank* of the same item type. (stats random after upgrading)
