I caved...and it paid off.

i told myself i would use my orbs only on the legendary banner, but i wanted Surtr so badly. so i summoned. my 124 orbs later and i get:
a +def -res Delthea
a +hp -res Surtr
and last but not least, a +atk -def Ylgr.
i now have 1 orb to my name but i don't care. i managed to get both of them and i even got my first Silas just in case i want to fodder SS4.
