Strider

As a sixth level Ranger, your deepened understanding and experience with Nature allows you to better harness her magical power to enhance your prowess in the wilds. You gain the following enhancements to your Natural Explorer, Favored Enemy and Primeval Awareness class features:

• After spending one week in a terrain other than one of your favored terrains, you adapt to the terrain and treat it as though it were one of your favored terrains. 24 hours after you have left the terrain you have adapated to, it no longer counts as your favored terrain. At 11th level, the time it takes you to adapt to a terrain decreases to 24 hours; 
• When you hit on a weapon attack against a Favored Enemy, you can re-roll the weapon’s damage dice and use either total;
• Using your Primeval Awareness feature, you can concentrate for one minute (no spell slot required) to sense whether any of your favored enemies are present within 5 miles of you. This reveals which of your favored enemies are present, their numbers, and the creatures’ general direction and distance from you. If there are multiple groups of your favored enemies within range, you learn this information for each group.
