Gortesh is a joke.
Just take out the flamethrower by the door, any force damage kills them- do it out of stealth. Likewise you can cast any fire cantrip on the bombs and gortesh will take 70-120 damage. I just shoved him from bomb to bomb and he died round 3. Easier fight.
Orin is actually hard as she has unstoppable, and has the ability to one shot you round 1.
No she doesn't. Literally a single magic missiles and her unstoppable is gone, potion of speed and she loses 60% of her health to a lv6 magic missiles. Then whatever martial you have mops her up during the same turn. Orin did zero damage to my team, they were all 21-22 AC including Gale.
And the bombs that were being thrown were bugged, so the grenade launchers were throwing the bombs at my characters AFTER they had already taken an action. Sometimes they threw two bombs on top of a teammate during one of my turns, and they would keep tossing more during that same turn every time interval if you wanted to test their launch pattern. The grenade launchers are bugged and are not respecting turn rules.
