For the Rook:
1. Sometimes when targetting Hammer Slam on an enemy in the distance and that targeted enemy dies a second later Rook will use Hammer Slam in front of himself. Note there were no other enemies or mines near him when he decides to do this.
2. Tower of light on Rook's shoulder shows damage to other Demigods but no other enemies, not sure if this is really a bug or not.
3. I think I may have noticed someone pointing this out before but couldn't find it again and didn't see it on http://demigod.kryofx.com/. You can get Structural Transfer II at Level 3 not 6, III at level 5 not 10, IV at level 10 not 15. (edit: and I'm blind, I just found another post about it)
4. Robust Health Potion can be used in middle of using Structural Transfer and it won't stop the casting. It will stop you attacking, in middle of casting Hammer Slam, and stop your archers from attacking though.
For demigod:
5. The message, excellent we got first blood seems to happen when the other team gets first blood. In the last few games I recorded what happened for deaths for the message appearing.
1 x I died once, no message but the second time I died during this game from another AI it said we got first blood. No other demigods died on either side during(before I died) this test as I could see them all still alive and smashing afterwards too.
2 x I died once from an enemy AI and it said we got first blood. No other demigods died on either side during(before I died) this test as I could see them all still alive and smashing afterwards too.
