At the start of the enemy turn, if you have no armour, sacrifice Plated Demolisher.
What Does Plated Demolisher Do?
Plated Demolisher is a great fighter with combat skills and the Endurance skill. It also gives you a one-off armour boost of two for your main character. All that for only 6 Power? There's gotta be a catch...
There is. To keep this card alive you need to maintain your armour. This value is reduced whenever your opponent does damage to your main character. A good defensive line on the battlefield will prevent much of this damage getting through, but won't stop spells such a Flameblast or unit effects such as that of Umbren Reaper.
It's tempting to use this card alongside Relic Weapons such as Mithril Mace or Sword Of The Sky King, but I'm not sure that's a good idea. Although these will keep your Demolisher alive a little longer, the actual weapon won't be much use as you won't want to risk attacking enemy units and taking armour damage.
