Both line of sight to or from a unit that has been joined by a character, and its vision arcs, are determined from the unit as a whole, taking into account any character models positioned adjacent to the unit. When required to determine line of sight for the character (for example, when casting a spell), do so from the character model itself as normal. In such cases, the unit does not block the character's line of sight.

If required to determine line of sight to the character, do so to the character model itself. In such cases, the unit may block line of sight to the character.
