Welcome to Librarium Online!
Here's what i've seen be played thus far with skaven, contemplating building my own for tournament play:
IDK items, no bel tho
3x Plague priests(lvl 2's) w/ furnaces
25x Monks pushing each furnace
3x units of slaves holding table deployment side table edges for VP's
2x Hell Pit Abominations
2250 list, beyond what i've written here i know nothing, particularly about magical items, elaborate please....
I wonder if there will be cake.....
3 plague furnances and one grey seer in one unit, swap a hell pit for scremming bell 4d6 s5 impact hits if that unit charge it take down everything (if it not dead because of magic)
but if you meet vampire counts you gonna lose very hard because they cause fear and that unit is almoust worth 1750 points.
Should take lord skrolk, if u wanna make a true pest list XD.
Skrolk-put him in the unit of censors, makes him soooo much better
3 Priests-lv2's naked
-i would recommend dropping a unit and a priest w/furnace to give FC's and items to the other units and priests.
-and your list is illegal if you dont take Skrolk, the way you have it written so far anyways.
