I'm working on a multiclass build and I can't decide where to put my last level. The character is a solo build mainly melee focused with self healing/buffing abilities. My options are a CL 13 Blade Barrier or +6 to all saves and no Blade Barrier at all. Like I said, it's more of a melee/healing build, but I'm sure BB would come in handy even at caster lvl 13 (especially with maximize, which I would only take if I was getting BB). Thoughts as to which would ultimately be more valuable in solo play?
