Conditional Actions (v1.1)
Some actions create constant effects that wait for a specific condition to be met in order for them to resolve. These actions are called Conditional Actions.
Conditional Actions last until the end of the turn or until their condition is met, whichever is first.
Hydra's action is not conditional action, but as you you see some Actions create Constants. About the until the end of the turn thing. Look at Demoralise. If you play it on an unit without any power and then the owner of that unit will boost it power that power will still be reduced by 2 although it happens after the resolution of the action (Baby squig gets demoralised in battlefield, waaagh is played later, baby squig has 0 power, because the effect lasts until the end of the turn).
Hydra's effect lasts until the end of the turn, it affects whole zone, so even units that later entry that zone are affected.
