Sigil of the Hunter, +2

This sigil is a symbolic representation of someone who has an intrinsic understanding of the ways of the hunt. When attuned, the sigil seeps into your skin and attunes you with nature. While attuned to the Sigil of the Hunter, you gain a +2 bonus to spell attack rolls and to the saving throw DCs of your ranger spells.

When you cast Hunter’s Mark through Favored Enemy, you have advantage on Constitution saving throws you make to maintain Concentration on it. If you fail a Constitution saving throw to maintain your Hunter's Mark, you can use your reaction to succeed instead.

Notes: Bonus: Ranger Spell Attacks, Bonus: Ranger Spell Save DC, Ranger, Buff, Combat
