Celtic Heroes

I have been farming those Giant Sewercrawlers in search for Shadowstrike. In the 3 days straight that i have been doing this i have got:
2 Frostbite Tomes (Mage)
4 Defensive Formation (Warrior)
2 Stinging Swarm (Druid)
2 Explosive Arrow (Ranger)
3 Skewer (Ranger, Rogue, Warrior)

But... NO SHADOWSTRIKE!!!!!
Am i just having bad luck? If not, why can all skills but shadow drop in that area? Can the Ancient wyrm drop it?
Im so confused, please someone tell me whats going on.

Imo it is one of the rarest skills in the game, and im pretty sure its random in all places, just realllllly rare, i got one from a regular wyrm in sewers, but thats the only one in months of farming/lvling.

That's still about right, I had over 30 books in there before I got shadowstrike for my rogue.
