Shadowheart with 135 HP is seriously buffed up. At L12 she has 87 normally.
She relies heavily on illithid powers. That's a game choice you make which may have consequences for your character. If you take it, OK. Obviously you will have an easier game if you grab all these extra powers. In the game itself, these tadpoles are an interesting dilemma. Swallow or not.... not knowing when or if you'll transform..... For a video about a boss fight, this dilemma doesn't matter of course. In the scope of the total game, it is also an aspect of the "difficulty".
I understand it's not the first time she does this encounter and the first one(s) failed. So it would be quite harsh if you repeated this time and time again and never found a way to win.
I finally decreased the difficulty level from standard to explorer for the first time in the house of grief. (at lvl 11)- Got wrecked on standard difficulty, even thoughh I came prepared with a fire elemental by my side and Gale having spiritual weapon from his staff, so even with 2 extra fighters on my side. Game is difficult enough for me.
