+*randomoptgroup <random option group ID>;
+
+This command fills the following arrays with the results of a random option group.
+The random option group IDs are specified in 'db/(pre-)re/item_randomopt_group.yml'.
+
+Arrays - from index 0 to MAX_ITEM_RDM_OPT-1 :
+.@opt_id[]                - array of random option ID.
+.@opt_value[]             - array of value.
+.@opt_param[]             - array of param.
+
+Example:
+	// Fill the arrays using the random option group ID 5 (group used for Crimson weapons).
+	randomoptgroup(5);
+
+	// Create a +9 Crimson Dagger [2] with the Group 5 applied
+	getitem3 28705,1,1,9,0,0,0,0,0,.@opt_id,.@opt_value,.@opt_param;
