Hello again
1. Players who have Power 1 (hero) can fly and be invisible, but for some reason when they leave the invisibility - can not attack creatures in their pets, too, can not attack (no information about UnVulnerable of Power 1 I can't find) and Heros can't use commands ~#vulnerable.
2. Power 1 can fly , but if they fly on water - he loose stamina and get water wounds and can die
