Siege on Dragonbane Keep: Snack Attack

Easy to solo.

You need to feed Beef 20 times. You don't have to do it all in the same siege. You can work on it over the course of as many as it takes.

Right when the event starts (Stage 1), head to the south part of the event area (highlighted on your minimap.) Beef will start there. There are snails on the side of the road. You right click the snail and use your action button which appears when you are near Beef, to feed him. If you cannot click on the snails, /reload. I had to do this multiple times for some reaosn. Enemies will attack Beef but he has guards which will kill the enemies. Stage 1 will autocomplete by itself even if no one kills anything. However, I don't think Beef starts moving until a player approaches him for the first time.

It's probably easier to get snack credits when you are there alone. Luckily the meta right now is to form a mega-raid in one shard and ignore all the others. So if you show up right on time and don't realm hop, you are likely to be alone and that's fine. After you finish, you can do the other Siege on Dragonbane Keep achievement, which is also easy to solo.

Some of the snails can be found in stumps and trees. This macro can be useful to target and mark them with a skull.
