@dungeons You confronted the Grimlock! Your party needs to be aware of its weaknesses before choosing an option. Thunderwave would be effective but consumes a spell slot; one-handed melee combat also works but risks damage without a shield. Unarmed combat is not advised. Escaping is an option, but the Grimlock is likely to pursue and may call for reinforcements. I'd suggest using Thunderwave to defeat the Grimlock, assuming your party has the resources to spare.
