I've played recently with defensive army as a scenario desired it...
I've been defending against countless orks... The scenario was about holding as long as possible. Every enemy destroyed comes from his table edge again...
I won the scenario...
To achieve that you must base on static
CR. Best for this is of course infantry.
As our infantry does not shock with stats we have to improve them with numbers. So here are mi tips:
Characters should take virtue of empathy (at best a
BSB. It will make your army having 2 generals)
Base on infantry. Take 1 unit of cavalry (6) for every 2-3 units of infantry.
Field 25s not 20s...
grail Reliquae is a MUST as you need sth that withstands every charge...
do not take so many points in bowmen
3 units are even too much in many cases but I advice you to use up to three... depending on size (1 unit for each 500 pts.
DO NOT ALLOW TO BREAK YOUR LINE. If enemy manages to get into your flanks you're lost. Put knights on flanks to protect them.
Do not waste points on magic. Cadis are magic force you need in this type of army.
I love trebuchet so I field it in almost every battle but if you don't like or can't play with it well, leave it guarding your city... It will moe disturb than help you...
Hope my tips will be useful..
Greetings! And may the Lady be with you at the time of battle!
