GM OOC: Yes, that is correct, and you succeed in the attack, roll for damage. Also, you have Hope, so give yourself Hope.
Necro OOC: Oh yeah, I shall do that.
OOC: mmkay so like...what happened to the goblins?
Oops forgot to roll for damage!
GM IC: Both Necro and Elisa work together with their fiery and wooden attacks, eliminating 4 goblins in a single go. The large group greatly shrank to only a few goblins left.
OOC: so can I like......parkour off the walls to get a running start and just like bam bam bam like run across those goblins like bowling pins?
GM OOC: There is no wall, as this is a decent-sized chamber, but there are plenty of goblin huts and stone half-walls that you can use instead. In that event, roll an Agility check with a DC of 10. The difference between that and your number above that determines how many goblins you successfully take down this way. However, if you roll with Fear and didn't take them all down in the first try, then you are putting yourself in a perfect spot for them to Group Attack you with advantage because you run into their group of spears, same for if you fail the DC of 10.
GM IC: Elisa immediately bounced and spun around the half-walls and huts at high speed, taking out goblin by goblin with each run until they all were lying there unconscious.
Necro IC: Necro swung his greatsword, decapitating unconscious goblins one by one as they breed fast, so leave one alive, risk a horde returning in the future.
Necro IC: "We are in a dungeon infested by goblins. I was contracted to deal with this infestation before goblins grow large enough to overrun the nearby village." Necro explained as he held the greatsword tightly while looking for where to go next.
GM IC: Both Necro and Elisa wander through the dimmed, narrow hallway, which is lit by spluttering torches, before it sharply turns east into yet another hallway altrough this one is wider before it narrows again in the end.
Necro OOC: Okay.
GM OOC: Both of you succeed. Also, @harshmnr, don't forget about Hope, since you didn't mention it.
Necro IC: Necro turns to Elisa, "Good thing we found this secret passage. They are blind and slow but lethal on contact. Dungeon Cleaners, we call them. We should be able to check the chest without them doing anything to us as long as we don't go under them... unless you think you can handle them?"
GM OOC: You can roll for it, but unless you are using something that asks for it, it is generally better not roll for it unless either you want to risk potentially backfire for narrative purposes or I ask for it. Unless we play together enough that you know when you will be asked to roll, or not to save everybody the time of asking each other to roll.
Necro IC: Necro just walks over and pops open the chest to see what goodies are inside.
GM IC: What greeting Necro when he opens is a dull prism object.
Necro OOC: Okay, let see what I got.
GM IC: Necro was able to identify it as Arcane Prism, an object that is used among spellcasters.
