Easy Way to get to get rid of Bone Dragons?

[Shadowcran]

Inquisitors or Priests. They alone basically make undead an easy prey. I use the reserve skill and keep priests in there, but Inquisitors are a permanent part of my troops.

With Priests in reserve, you can trade them into battle before you face Bone Dragons. If you have the Inquisition Skill, when at a castle(where you can leave troops), you can use it to fill up your Inquisitors spot with more by converting Priests.

With both reserve spots you can keep one empty, but the other Priests. You put one other troop(not Inquisitors) into the empty reserve, then find out how many Inquisitors you need. Use the Shift key while putting Priests into the now empty troop slot and put how many you need to upgrade to Inquisitors there. Then convert them. Easy to do once used to it.
