Glimpses of Hyboria
Varying degrees of cover
Sometimes cover provides bonuses to Defence and Reflex saving throws.
In such situations normal cover to Defence and Reflex throws are doubled, to +8 and +4 respectively.
A creature with this improved cover takes no damage at all if successfully saving against any attack to which the reflex saving through applies.
Even if he fails, he only takes half damage.
Also, Cover provides +10 bonus on hide checks.
