The Incredible Adventures of Van Helsing III

As another alternative I completed it as the Protector class.

I had not long finished VH 1 using the excellent guide written by MushaConvoy



So I followed the same principles, the only negative is that this time there is no 'panic button' to escape if you get into trouble, but the game is a lot easier than the first, so you should be fine.

Class: Protector
Difficulty: Casual

Stats
Everything is going into Body - nowhere else

Skills
The Spike Strike is very powerful, even at the very end it was 1 hit killing most enemies, and stops you from being swarmed - you want to max this out. Also maxing out Mightbane Spikes and Field of Spikes
The other focus is on Smashing Blow which you will want to max, initially focus enough to unlock Vampiric Onslaught which you will want to max out.

I periodically spent points on Aura of Vigilance to keep up my defence/resistance stats to make sure I was levelling with the enemies - I ended up with 8 points in here, I wasted 3 points on Aura of Fortune to try and get better equipment, don't think it made a difference, so could be spent elsewhere

I also put 4 points into Frost Sphere with 2 in each of the passive skills it has.

Auras
I placed 3 points into Rampage
When the 2nd slot is unlocked I worked towards 10 points into Ward Wisdom, with the 2 passive skills also unlocked.
I put two points into Hunter's Rejuvenation to help keep that HP topped up - this one is probably optional

Katarina
Set her to Ghost mode.

Ability Points all will be spent on Body.
Skills All under the Sentinel Tab, the first 4 in the left column
I had maxed out Empowering Presence and Gift of Resistance, which you should work on first.
I had 6 points in Incorporeal Defense and 5 in Spectral Boon

Perks
As you unlock them through natural playthrough I used:

Veteran Hunter
Survivor
Golem
Bully
Berserker
Precise

I carried the last 4 points right until the end, they aren't required but I would advise to respec (through Gaspar in the lair) and put 100 points into Dexterity so you can grab:

Gunslinger

Then move 100 into Willpower to get:

Resistive

and finally into Luck to get:

Destructive
Devastator

Make sure to put all your points back into Body when finished.

Items
I just went with the auto-equip, no set was needed like the first game, I spent little effort on Essence improvements, I did periodically ensure I had enchanted my items with Saffi, but only when I was back at the lair, mainly to try and boost resistances to be on the safe side.

These are my final stats as a reference:

This achievement is MUCH easier than the first game's was. Biggest tips are:
1. Make Katarina the tank, with buffs to your defenses and survival.
2. Be ranged in some way shape or form.
3. Make sure to have an escape skill, doesn't matter which one
4. Put about 25-30% of stat points into body.
5. Do side quests to get permanent boosts.

I've done this with the Umbralist Class, Like Gunflame said put most points into Body first, then some on Dexterity. I had over 100 body, 67 Dex in the end. Katarina is tank, Side Quest for max exp/skills. Play on Casual!

My skills were Blink Assault 15 max
Shadow Jolt 15 Max (Important to get cooldown)
Shadow Warriors 2 (1 on each)
Shadow twirl (useless)

Auras
Telekinetic Aura
Hunters Rejuvenation
Power for Blood

Perks
Mentor
Wraith
Wight
Bond of Fury
Bloodthirsty Ghost
Veteran Hunter
Uncanny Fighter
Survivor
Berserker
Ghost Whisperer

Most of the times you will be using Shadow Jolt and Blink Assault.
