2nd Crusade

The elixir only heals for 50 hp. Spheres only affect attack magic. This has always been the case in SoD, and it's generally well-known, so there's no need to blame the HD mod.

If a stack was already moving in a round when it died, it will be resurrected as "already having moved," even in subsequent rounds. However, if the stack was just waiting to move at the time of death, the wait time does not carry over to the next rounds.
There's also this feature: if players have the same maximum creature speed, after the Catapult's turn, the attacking player always gets the turn advantage (contrary to the usual rule, where the player who didn't move in the previous stack gets to move).
