Deciding what you were doing was the best course of action currently, you continue to rain down explosive arrows on your enemies, however you realise you cannot do that and get up a tree as the canopy here is too thick. You are now a ways into the forest.
Most of your shots fly true, and before long you have destroyed the wraiths and banshee due to their inherent weakness to magic, and about half of the undead following you are missing limbs or are immobile, although none died. The rest seem to be moving faster.
You did manage to kill one of the Angel Spawn, although the other two are still in great shape. Well, as great as a rotting, walking, flesh-dripping former-human can look, anyway.
You circle around and try to dodge through them to get back to the main fight, however that does not go as planned. The undead manage to block your way still. They seem to want to keep you away as much as possible. You can still hear the sounds of battle and the terrible laugh of the Angel. You cant help but think the sound of spells being cast and launched has receded a bit and the background power you usually feel associated with magic is decreasing.....
To make matters worse, darkness is falling, meaning they will be stronger. Fortunately, it also means your abilities improve as well, albeit only slightly. You can, however, see in the dark. You feel a slight twinge behind your eyes as your eye colour changes to a gleaming gray colour from your usual brilliant ice blue.

Your attacks were effective, but not overly so.
What do you do now?
