Path of the Giantsbane

Your clan lives in the high mountains and because of that have been in conflict of some kind with giants for generations. Because of that you have developed special techniques and powers to conquer these foes and other large creatures. Over time you have taken some of the powers and abilities of your foes and taken them for you own.

Giant Bane

You gain knowledge about giants to better fight them. You learn giant and have advantage on checks for recalling information about giants and tracking them. When you are raging you can use your action to enlarge yourself. You can do this one time per long rest. You gain another use of this when you reach 6th, 10th Level and 14th Level.

Stone's Bombardment

The stone giants while not outwardly hostile to outsiders will aggressively defend their territory against intruders. You yourself have seen the crushed corpses of those who fell under the hailstorm of rocks thrown by stone giants. You have learned to emulate this. You can throw rocks or large stones as a ranged weapon attack range of 30/120 that you are proficient in dealing 1d12 plus STR modifier bludgeoning damage. Also as a reaction you can intercept a projectile or projectile like effect(the spell catapult or other similar spells) that deals bludgeoning damage and reduce the damage by 1d12 plus your STR modifier.

Frost Vitality

You often fight these creatures in hostile environments in mountains and wastes. One of the fiercest of these is the Frost Giant, an powerful foe that shrugs off the cold and ice. In order to face these creatures you must be able to do the same. You gain resistance to cold damage and you have advantage on any checks related to surviving in cold or mountainous terrain(Survival checks, and constitution saving throws against cold weather)

Fire's Wrath

You may not have seen these crimson warriors in the mountains but as miners and explorers delve into their mountains they emerge to crush them an it falls to your warriors to drive them back. As a result you have learned the traits and techniques of the Fire Giants. You gain resistance to fire damage. You gain proficiency with Smith's Tools and gain the ability to infuse weapons with a bit of the Fire Giant's smithy power. At the end of a long rest you can touch one non magical weapon and use smith's tools to grant it a +1 bonus and extra fire damage equal to your proficiency bonus that lasts until you take a long rest.

Storm 's Fury

Storm Giants are the greatest of Giant-kin reigning from their great mountaintops striking down those they find unworthy with their mighty lightning bolts. You harness their power to embolden your power and rage. You gain resistance to lightning damage. When raging you can unleash the Storm Giant's fury bringing down your own lightning. When raging you can use your bonus action to unleash a lightning bolt from the sky on a creature within 30 feet of you causing them to make a DEX saving throw (DC = 8 + CON modifier + Proficiency bonus) If they fail they take 5d6 lightning damage, half if they succeed. You can do this a number of times equal to your CON modifier per long rest.
