Guerrilla Fighter

Guerrilla warfare is a form of irregular warfare in which small groups of combatants, such as paramilitary personnel, armed civilians, or irregulars, use military tactics including ambushes, sabotage, raids, petty warfare, hit-and-run tactics, and mobility, to fight a larger and less-mobile traditional military.

Extremely Evasive

At 15th level, When you are subjected to an effect, such as a red dragon’s fiery breath or a lightning bolt spell, that allows you to make a Dexterity saving throw to take only half damage, you instead take no damage if you succeed on the saving throw, and only half damage if you fail. When an attacker that you can see hits you with an attack, you can use your reaction to halve the attack’s damage against you. You are so evasive that attackers rarely gain the upper hand against you. No attack roll has advantage against you while you aren’t incapacitated.
