Line of Sight is a restriction for most spells. These spells can only be cast on a target that the caster has an unobstructed view of. Other creatures and static objects in the combat area can block this.
No LoS Spell
Only a handful of spells do not need Line of Sight to hit a target and have a substantial enough range to benefit from this.
|Word of Resurrection|
|Gift of Life|
A number of effects allow you place objects into a fight to obscure the Line of Sight. This can be used defensively, though unless you have some attacks which do not need LoS, you can often find yourself at the same disadvantage.
- "Line of Sight" is often shortened to "LoS".
