So now I'm questioning my decision. Wondering how others would handle it.
Party is tracking a band of goblins across a grassland that kidnapped a young woman. They are ambushed by a small group of goblins and wolves. It's night, they have 2 torches lit. Grass is waist high, easy enough to hide goblins, though wolves need to be prone.
Goblins roll high stealth. Only one with high enough passive perception to notice would be the ranger, but she's tracking, so by the travel rules she doesn't get a perception to notice. Wolves roll abysmally low, so everyone would notice them.
Except for the ranger. Grassland isn't her favored terrain, so because she's tracking she has no chance of noticing hidden threats. When combat starts, the ranger is surprised.
Question 1: Do you roll a Stealth check for each group of monster, or just one? Which Stealth do you use? Higher (goblin +6)? Or lower (wolf +4)? Or split the difference (+5)? Or maybe lower, but advantage (for the Help action)?
I do what you seem to have done and roll a separate check for each group of identical monsters.
I then gave the goblins a surprise round, but left the wolves out. I am wondering if that was correct.
No, in the first round everyone except the ranger goes on their turn in initiative order. Once the ranger's turn is over, she's no longer surprised.
Question 2: Should I instead have given no surprise round (players should have known something was there, because terrible wolf rolls) and given the goblins advantage on their first attacks for being hidden?
No one except the ranger is surprised because everyone else noticed the wolves even though they failed to notice the goblins. No matter how low the wolves rolled, however, the ranger would not notice them or the goblins because she is not alert to hidden danger. If the goblins have a ranged attack available to them, they can attack with advantage from within the dense foliage. The wolves probably have to come out into the open to attack and no longer be unseen.
Thanks for the input.
You're welcome.
