Monster Attack/Spell Block

There are two separate stats: chance to block attack damage and chance to block spell damage. But there is no way to tell what's an attack and what's a spell, except when the monster is actually swinging at you. Any other skill they use could be an attack or a spell.

This is highly confusing. Why do monster abilities need to be tagged as spells or attacks? And why do we need two separate stats for it?

Please merge the two block stats into one: chance to block damage.
