HORRORMANCER - low budget beginner friendly

How do you "spec out" of mana? In your build, you put your 3rd, 4th and 5th points into mana while you level, but then somehow respec them into energy shield later on. Do I really need 40 respec points to do this, or am I missing something?

You just pick up the 3 energy shield points in starting area and refund your 3 mana points.

Can you please update the guide and skill tree with the changes discussed above?

i'm quite new to the game so sorry if my question is idiot, but why you bloodlust if nothing causes bleeding in this build?

Any idea?
