Guardian of Nature (War of the Burning Sky)

Nature exists in a symphony of relationships with the creatures that inhabit it. Some relationships are harmonious while others are explorative, but the actions of some creatures are so destructive as to sever their bonds with nature and leave destruction and suffering in their wake. When the safety of the natural world, its resources, and its creatures, are at stake nature chooses guardians to restor the balance with it's creatures, sending fey companions to accompany them on their journeys.

In War of the Burning Skythe land has suffered greatly under the ravages of war. The forest of Innenotdar has burned for decades. Resources are strained as refugees of the Tafesia's advancing Scourge flee for their lives. Even the sky itself burns those who try to teleport. 

Fey Companion

At 3rd level, choose a beast of challenge rating 1 or less. When you use find familiar, you summon a fey spirit as nature’s emissary to accompany you on your journey, and the fey spirit assumes the form of the beast you chose. This use of find familiar has the following changes:
• The familiar is a fey spirit.
• The familiar always assumes the same form.
• It may attack with any actions in its stat block.
• You cannot dismiss the familiar.
• You cannot cast find familiar again until your
current familiar disappears by reaching 0 hit
points.
As you gain strength in your travels, so too does your companion. At 4th level, and again at 8th, 12th, 16th, and 19th level, you increase one of your companion’s ability scores of your choice by 2, or you can increase two of its ability scores of your choice by 1. You can’t increase an ability score above 20 using this feature.
Your companion also gains Hit Dice equal to your proficiency bonus in addition to the number already listed in its stat block.
