Flicking Sticks and Taking Names

Slay the goblins, defeat their leader, and reclaim the area, so that travel through the forest will be safe once again.— In-game description

Strategy
This guildhest features a mini-dungeon filled with goblins.
When fighting goblins, they will periodically drop bombs on the ground. Be sure to get out of the bomb's red circle before it explodes. When you progress through the dungeon you will encounter barricades. While you're damaging the barricades, the goblins behind the barricades will throw bombs at you. Avoid the bombs when possible.
In many cases, once the crate is destroyed, the goblins will automatically aggro the player at the front of the group. If a dps or healer is ahead, they will automatically pick up aggro. Try to stay behind the tank to make is easier to build enmity. This is a similar mechanic to The Vault dungeon in Heavensward.
Stikflix Grumblytoss
Stikflix Grumblytoss is the goblin boss of this guildhest.
He is able to throw multiple bombs at a time. At the start of the fight, Stikflix will throw 3 to 4 bombs at the time. This number increases through the fight. At the end of the fight, Stikflix spawns about a dozen bombs on the ground. At the very end of the fight he throws a large bomb with very large radius.
