Generally counters do not increase when upgrading or pacifying items, but some medals do. I know that my Valhalla's Messenger was increased by one when upgrading an item with Viking troops.

I read somewhere that the Sacrifice spell was the only way to resurrect all level 5 creatures, so I invested in black dragons and ice dragons. When the time came to increase their number I found out that the Sacrifice spell has the same restrictions as the Resurrection talent of the Inquisitors: Plants, Ice Creations, and Black Dragons are excluded. I reloaded the game before I acquired the dragons and replayed from that point.

To my knowledge there seems to be no way to resurrect black dragons. Fauns can resurrect plants, and some cold damaging spells can resurrect ice creation creatures, but I have not found anything that works on black dragons.
