I used the search feature and wasn't able to find the answer but could have sworn that I saw it somewhere here. The question is, does a monster of 4+ tiles move the same as a single tile creature? Does an orge knocked back still move 1 of it's tiles 3 spaces or is it reduced due to it's large size?

Thanks!

It's in the FAQ.

Knockback and Large Monsters
Large monsters (monsters that occupy more than one space) are heavier and therefore less affected by Knockback. For each space beyond the first that the monster occupies, it is moved one less space by Knockback. For example, an ogre occupies four spaces, so it would move three fewer spaces when affected by the Knockback ability. A dragon, on the other hand, occupies six spaces, so it would move five fewer spaces.
