Epic Ranger 23nd Level

Master Explorer - Beginning at 21st level, while in your favored terrain, your group cannot become lost, even by magical means, and your entire group may move stealthily at a normal pace. Upon reaching 25th level, you may choose a fourth favored terrain, and you have advantage with Insight, Investigation, Nature and Survival checks while in any favored terrain of yours.

Ability Score Improvement - When you reach 21st level, and again at 25th and 29th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. Contrary to earlier levels, you can now improve your ability scores up to 24 using this feature.

Extended Spell Capacity - Beginning at 22nd level, you gain an additional 5th level spell slot.

Strider - No magic can reduce your speed below its maximum and no solid terrain is considered difficult terrain for you.

Deadly Foe Slayer - Your Foe Slayer ability lets you add your Wisdom modifier to attack rolls and damage rolls simultaneously. Upon reaching 29th level, your Foe Slayer feature is no longer limited to one attack each turn, granting its benefit to all attacks against favored enemies.
