Titanic Hydra is broken
I may or may not actually write a guide later.
The Lv1 is easy, you put two boxes are your gromp or golems, and two boxes out of the way from your starting buff. You then kill gromp or golems then proceed to put a third box down and lure the buff to the 3 boxes and kill it. If you do it right, you'll take no damage. It's important to make use of your passive. I personally only buy two potions, but if you can get three.
I won't say more as far as tech, positioning, or actual advice. I'll just say that this build sets out to do what other builds want to do but better. It does more burst, more DPS, and is a **** ton tankier.
