Muchas gracias for this clarification, again
Other than that, this turn was a world of hurt for me - lots of Horrors (not the lesser version... playground time is over) and half his army. Gath will probably claim the other half crushing on him, sure, but at least I managed to get his Heliophagus down.
Not really my achievement, though, since a Heliophagus, just armed with two fire gems (..) isn't that strong in close combat. Puh. Now, who invented that Astral Corruption thingy?!
