They are responsible for RuneScape Gold telling the warriors what is coming there way since they're generally on the high ground. However if the position gets cluttered, the archers will be told grab their bows and arrows and run back to the Salve.
Before they become overrun however they have the capability to perform several options.Sneak around and attack the Myortanian camp or stay on the high ground and snipe the attackers. When you're attacking, you will have just 1 interface, a combat interface.
When every-man-for-himself is shouted, it is time to return to the Salve. When you get back to the Salve you're told to build barricades and establish a raft to begin getting the wounded out. As soon as you are told what to build, you'll have two minutes before the vampires get into the Salve.
Once the vampires get to the Salve, you're advised to fallback across the river and begin to fight from across the river. Once across the river you need to fight and hold the Salve for 5 minutes while forces from Varrock come to encourage you.
The Warriors within this minigame are the backbone of the minigame. If you are a warrior you're on the frontlines. You'll be assaulted by 50 level 30 witches first. If you hold them off you will be assaulted by 50 level 50 vampires. If you manage to hold them off you will be assaulted by 100 level 50 vampires.
Whenever you're overrun you are told to fallback to the Salve and hold off the remaining vampires until support comes. When you drop back you'll be attacked by one wave of witches under you. For example: If you were on 50 level 50 vampires, then you will be assaulted by 50 level 30 vampires. Do not worry though, you aren't the sole person to be battling the vampires. You will have 3 additional warriors along with 56 Misthalin soldiers (level 50). When you are overrun though, all you will be advised to Buy OSRS Gold fallback.
