Welcome to Librarium Online!
i would be grateful for nay constructive criticisms/advice anyone could give me on the following 2400 point list.
screaming bell and dispel scroll
2 warlock engineers-220
warp energy condenser
spears and shields
musician and standard
warp fire thrower
30 plague monks-220
6 rat ogres-248
(The 50 clanrats will push the screaming bell and the 30 plague mocks push the plague furnace)
I highly recommend you consider dropping the Rat Ogres for a group of ten Gutter Runners with Poison and Slings. They're absolute legends. Literally.
Also, consider a Ratling Gun for one of your Clanrat blocks. Have some variety, and give yourself some options if you don't come up against a horde.
P.S. just realised you only have 30 monks pushing your furnace! Man, you need some more! Forty would be good, fifty is great (I wouldn't go higher than that). Use those spare points from the rat ogres.
The screaming bell, isn't all that its cracked up to be . Its too random, and your opponent will just shoot at it til its destroyed . You're better off placing your seer, in a pack of clanrats or stormvermin, and give him some magic items .
The furnace needs protection, so you might want to consider the "shadow trinket", in the skaven armybook .
Rat packs, pushing either the bell or furnace, must always be 50 models strong . If they don't move, they're practically useless .
You'll want to protect your BSB, so find a way to give him a ward save . Also, give him a halberd .
Rat ogres are rather fragile . You could have a group of 3, as a flanking unit . Other than that, I rather go with giant rat packs or gutter runners ( adding an assassin with warpstone stars ) .
When taking a HBA, always take the warpstone spikes . Also, look into taking warp lightning cannons, as they are your monster/cavalry killers .
As a side note, your post should have been in the "army list" section . A forum MOD, will probably move it there soon ...
