Today we're going to talk about the strategies available to the enterprising Clan Pestilens player and the tricks and tools of the disease trade. Some of these aren't exactly unique to Pestilens, but all of them are useful to them.
The Prayers of a Righteous Rat
Did you know you can cast the damage prayer on the Plague Priest scroll without an actual target? It targets an area, not a unit. Interesting info, but not really useful right? Wrong. Spam this turn 1 with no valid target and go for a great plague, and select the Neverplague. The only excuse to not be spamming plague breath on empty spaces is of there's actual targets available or you already have the Neverplague.
Weather the Storm
So the enemy is unpacking his Beastclaw/Khorne/Daughters of Khaine. Our rats don't have a chance against such famous combat geared armies right? Wrong, they're as good as dead already. When the enemy is running an all charging minimum shooting list there is but one answer. Lines of single file plague monks across the edge of the deployment. Ideally 2 or 3 groups of 10, 6" gaps between them to stop the enemy squeezing past. Behind this line, 6" back (for safety) is a gigantic blob of plague monks. The first line will gey hit like an avalanche and they will almost certainly die. The enemy is now within range of a fully buffed, fully packed Plague Monk swarm. Chuck on some prayers of Wither on the enemy, move forward into range and charge (taking the Congregation of Filth will prevent double 1 rolls). Doesn't matter what they're running, they're dead.
Conga Line of Death
Never move your rats around in squares, this isn't fantasy battle. Squeeze as much use out of the rat squads as possible, form a long line and hold an objective while also screening for a priest and keeping an enemy tied up in a dud fight. Form circles around objectives, wrap monks around furnaces to prevent units with 1" range weapons bringing the furnace to battle. It's not dirty, it's alternative tactics.
Discretion is the Better Part of Murder
Retreat, it's the golden move no one ever uses to their advantage. Charge an enemy, then retreat around the side of them the next turn. Your enemy is likely to know he can't actually beat plague monks in a fight and won't charge them, so if you're already holding an objective don't charge off it. There isn't always a nees to fight. Know when to fight, and when to wait.
Below are some pictures of silly rat movements that would win me the game. Doesn't matter if it looks stupid, as long as you win.
