After recently reading the latest Warhammer Rulebook, I realised that there are no real Earthwork/Breastwork rules, that attackers would use in sieges and such. I'm going to say firstly that if such a rule does exist then point it in my direction ASAP and ignore the rest of this post.
This terrain would look like two long, diagonal, earth banks, one on each side of the unit
Now, this terrain would have to contend with hard cover, so it has the following rule:
-3 to hit on all shooting attacks aimed at the defending unit's front or rear, but no flank bonus
In CC, it is -1 for enemies to hit the defending unit and counts as Steadfast
This is a very powerful rule (likely
OP), so to balance, a few points -
The unit within the section of Earthworks can only deploy in two ranks (deep)
Due to the tight nature of the trenches, there is little room to dodge and so the defending unit suffers from (Insert technical name here) rule, that causes a wound for each point it loses the combat by
Furthermore, if the unit ever breaks from a lost combat it is immediately destroyed, the enemy unit acts as if it has just defeated an enemy occupying a building
Still over powered? Or useless? Open to any and all suggestions
