This topic has come up quite often I'm sure (or at least I'm pretty sure it did back on the old Specialist Games forums before GW shut them down, as I do remember seeing the odd thread there before).
However, it's in the consideration of the methods that others might use to combat heretics (or... colleagues with a difference of opinion) who happen to use power armour, or other assorted items that can often be considered to be (in rules terms) rather strong.
A rather amusing discussion coming from someone who enjoys building space marines in 54mm, no?
But to the topic at hand: how does one deal with such situations when lacking in suitable firepower?
I mean, not all inquisitors will have access to imperil guard armouries with meltaguns, plasma weapons (except maybe the odd heirloom piece) krak grenades, etc etc. And 10 points of powered armour is often quite a lot to deal with given that the average Inquisitor is not necessarily toting around plasma or bolt weaponry unless they happen to spend a lot of time on the battlefield, or have friends in high places.
Most of the time, they're lucky to have shock weapons, swords, las weapons, projectile guns, and maybe one or two other things. And they probably don't have more than flak armour, or maybe carapace armour if they're really prepared (or 'borrowed' it from the arbites).
So what's the solution?
All I can think of off the top of my head at work is to attack any exposed power cables, or to utilise shock weapons to somehow screw up the power source for the armour, as Haywire grenades are going to be even more rare and hard to come by than a plasma weapon or krak grenade.
One assumes this would be represented by allowing the player to make attacks against the opponent that do no damage to the target, but instead are rolled against possible locations of exposed cabling or thinner portions of armour, or against the backpack if they manage to charge in from behind.
What other possibilities are there? Suitably overloading a las-weapon powerpack (as per the short story in the Eisenhorn Omnibus) after sticking it to a weak spot?
Is it possible to drop part of a ruined building on their heads (not sure how to do this without suitable explosive supplies...)?
Thoughts? (on a postcard to...)
