Path of the Titan Slayer

If you chose The Path of the Titan slayer then that means you either hate titans or they betrayed you. You will do whatever it takes to kill the titans. You see the titans are a nuisance that need to be exterminated.

Titans Touch

Starting when you choose this path at 3rd level, you can go into a stage of pure power. If you do so, for the duration of your rage you can make a single melee weapon attack and if your opponent fails the strength saving throw he would be knocked prone. If you do this twice you will suffer one point of exhaustion, but you can do this once per long rest. At 6th level you can do this twice but if you do it a third time you will suffer one point of exhaustion. At 12th level you can do this to everyone in a 10 foot radius in a cone shape in front of you. At 18th level you can take a short rest and instantly get your two uses of titan touch back. 

Will of the Slayer

Also when you drop to 0 hit points you can use this ability as a reaction and you would succeed all your death saving throws and gain 1d10 plus your constitution ability modifier to your hit points. But only if you drop to 0 hit points. At 12th level you can use this ability even if you don't drop to 0 hit points. At 18th level you can never be frightened, and you can gain 2d10 plus your constitution ability modifier.

True Slayer
