Dragon Force

This ability is said to be the final and most powerful state a Dragon Slayer can attain, and it has been said that their power becomes comparable to that of a real Dragon's and your skin turns to dragon scales. When this activates you take half damage from any kind of damage magical or not, you also gain +2 AC, +5 to hit and damage for spells and regain 3 spell slots of your choice (level of spell slot does not matter). You can only use this once per long rest and after it ends you suffer level 2 exhaustion.
