Path of the Arcane blood

Most barbarians use only brute strength to help their people but arcane blood barbarians use the well of arcane energy inside of them to fight with brute strength and arcane powers

this allows you to cast spells

Arcane Fury

Starting when you choose this path at 3rd level, you can draw from the arcane well from inside you to cast spells when you are raging but these spells cost double of their spell slots

Magical surge

Beginning at 6th level, you use the energy inside of you to surge magic into your arms and weapons for 1 hour you and your weapons become magical attacks

once you use this feature once you cant use this again till you short rest or long rest

Spell rage

Beginning at 10th level, You can use the arcane blood inside of you to turn your rage into a spell rage, when you do this you gain the effects below

• you can cast spells for their regular spell slots
• you can concentrate on spells
• your spells gain the rage damage bonus if they deal damage
• you have advantage on strength checks and strength saving throws and concentration saving throws
• you have resistance to fire, cold and lighting damage
• you lose the regular effects of a rage

you can do this for the amount of rages you have 

Arcane resilience

Starting at 14th level, you can use the arcane blood in you to gain a resistance to one damage type that isnt slashing, piercing and bludgeoning damage you have to change this damage type to another damage type every short rest

whenever you rage the resistance becomes an immunity to that damage type
