In the hidden corners of the world where magic intertwines with nature, there stand the Arcane Keepers - guardians of enigmatic realms pulsating with arcane energies. Chosen by fate or circumstance, these rangers have dedicated their lives to the perilous duty of protecting the delicate balance between the natural and the arcane. Having immersed themselves in the very essence of mystical landscapes, they wield a unique fighting style that fuses the primal with the arcane, becoming sentinels of regions where the magical and mundane collide.

The damage type is of a spell that you have for that level or higher, of your choosing. For example, if you know the frost fingers spell, then you can choose for the damage type to be cold damage.

You can expend a higher level spell slot on this feature, the damage increasing by 1d8 for each spell slot level above 1st.
