1) The stealthy unit will attack.

2) once a site is revealed, it's revealed. Anyone who captures the province will see it. But they wont see what paths you have searched the province in.

3) The only thing you can win is the arena trident. A two-handed weapon with great attack/defence/damage and two attacks that also grants quickness as per the spell. So 2x2=4 attacks in melee. The one who carries the arena trident will automatically join the next arena event.

If the other fighters carry magic items, you can sometimes get those. In multiplayer you can get horribly bad cursed items this way.

Immortals die. The arena is outside the world.
