That battle is always a blast. I usually do 2 or 3, don't think I managed a full 4. A fear of too much ranged damage usually holds me back.
One thing to watch out for with the game changes is that the added experience bolsters enemy levels as well, changing the threat level in later episodes in comparison to earlier play throughs, in my opinion, especially in areas with very high level caps.
With the equipment changes, I run Kyera with max SP drain gear and 1 talent point of Sacrifice only. She is able to comfortably supplement SP to the party as long you as you make her a hammer striker for damage reasons.
As always patience is the biggest virtue in the game as it takes only one death to end an Ironman run.
I broke down and purchased Ep 3 equipment, as the 2 AP bow for Selen, 2 AP hammer for Kyera, and 2 AP blade for Kincaid bolstered my damage greatly. However, I don't plan on buying any more equipment through Ep 4, so my gold usage overall is quite low as I minimized everywhere else.
I’m about to do the Vurnak fight for the first time.
Going to blow a lot of Bloodstones on gear and try to be extra careful (A Spider Host took a full health Kjartan down to SIX hp in two hits when I was sloppy for just a moment yesterday) I’m also switching up my debuff order
