The stormwall will likely be ARM 18 and DEF 10.
So the magehunters will likely hit 5 times.
Assuming jack hunter works, which it likely will, the magehunters are getting 3d6 -8 on damage. So an average of 2 to 3 damage per magehunter.
So, even on the high end those magehunters will get 20 damage maybe a round? I mean that's swinging the damage a few points in the magehunters favour.
Stormwall will be 1) repairable and 2) somewhere around 60 boxes.
Yeah, min magehunters I'm not caring about so much. Or full magehunters.
And again, we have no idea what the offence on this thing will be. If those pods do what I think they do, magehunters might never get near it.
