It's intimidating to look at, but I have a lot less trouble dealing with an abomination than I do a Log Troll. The attacks are shorter range and easier to avoid/parry, and their path finding is far less direct/aggressive. An axe makes pretty short work of them. Fire arrows work, but frankly I think it's more of a waste compared to just dealing with the attacks and getting a chop or two in-between.

You can just wait for it to swing/stomp and then hit it with your axe as you sprint past. Repeat until you have toothpicks.
