I'm preparing for a large encounter in my campaign. Unfortunately, the DM likes to be a jerk to me when I try to do something spectacular, such as casting darkness over an area of enemies and then telling me the sword someone is using is shedding a magical light that dispels all that darkness.
So I need to be prepared.
I'm a level 5 shadow monk. I will be using Dust of Disappearance, a Cloak of Elvenkind, and the Pass without Trace spell before an encounter to gain advantage; however, I was informed that one enemy, if not multiple enemies, will have see invisibility.
Even though they have see invisibility, will they be able to see me if I get, say, an average roll of 27 on Dexterity (stealth) with bonuses? Could I, say, walk into the center of the opening without getting caught, or do I have to be obscured to remain undetected?
What is the limit of what I can do without being detected?
I'm playing D&D 5th edition, in the Out of the Abyss campaign.
