Path of the Colossus Slayer

Your rage transcends physical limits allowing you to imbue your spirit into weapons with a larger reach. This makes you a true threat to both the large and the small, the near and the far. Those who follow the path of Colossus Slaying are grand hunters, the best of whom are great heroes who fell foes of unfathomable might and size.

Level 3: Titan Rage

Your Rage taps into your very soul, imbuing your weapon with its strength. While raging you gain the following additional benefits.

• You gain the ability to use shortbows, longbows, and slings as Strength-based weapons rather than Dexterity.
• You gain the ability to perform Colossal Feats.

Level 3: Colossal Feats

While Raging and wielding a shortbow, longbow, or sling you gain the ability to perform Colossal Feats of strength. As an action you may do any of the following Colossal Feats that you have access to. Some require a target to make a saving throw, the DC equals 8 + Strength + Proficiency. Some require a weapon attack: These apply the normal damage and effects of the weapon, ammunition, or other applicable bonuses such as Brutal Strikes, as well as the effect of the Colossal Feat. You perform a number of Colossal Feats equal to your Proficiency Bonus and you regain all expended uses after a Short or Long Rest. (Ammunition is listed on all Colossal Feats for the purposes of tracking.)
