So, to @ravenvii, then, it would seem that a brisk trot is in order.
All out sprints are taxing, and, besides, I'm not one of those preternaturally effortlessly elegant Elves, although I have enough of the grace of my race to make a trot effective, balanced and fast: Hence, a brisk loping trot to the other Goblin (30 feet?) and will then proceed to employ the cantrip (yes, @twietee, you wanted some magic, let us see what this does) Shocking Grasp on the aforementioned goblin.
(Given the way those damned dice roll, and have rolled thus far, I'm more than afraid that the dice will ensure that my shortsword slips, misses, merely scratches the goblin after bouncing off, or stabs myself by mistake instead. Yes, it might indeed cause somewhat less lasting harm to our Goblin, but the cantrip stands a slightly better initial chance of some success. I hope.)
You were right behind Claus when you heard shouts and the sound of metal meeting metal beyond the briar thickets. As Claus ran for the unengaged goblin, you run to assist the halfling.

Syllin: 6
The goblin now has 1 hp.

>>> And it's now your turn, @Don't panic -- you likely know exactly what to do
