Creature animation

Hey, guys, I’m literally new to unreal so I been buying a couple of asset packs to get me going. however, i need some help with blueprints scripting a monster.
Something similar to
UE4 monster chasing and attacking Ai with inverse kinematics - YouTube.

I’m using dynamic combat system and Polygon knights and dungeon pack. also, I’m using a dragon that I created with for the monster. just don’t know how to get him going.
any help will be greatly appreciated and thanks in advance
