Can a player with Unstoppable win if some other win condition occurs?

This depends on the timing between this round’s attacks and the satisfaction of the other win condition. If the player with Unstoppable has not had a chance to attack this round, and another win condition is triggered, then the player does not also win. It’s a pretty simple win condition to achieve so we are giving priority to almost any other condition.

Can a player with Undefeated win if some other win condition occurs?

Yes, as long as the player has attacked another player at least once and won every time they attacked.

Please explain Encircle. It says you must surround an enemy on all sides minimum 5 turfs…?

There are some positions on the board that do not have at least 5 surrounding turfs (due to dead spaces, the waste, etc.). Those turf areas are not valid targets for Encircle.

What if someone kills my nemesis? Or my Kill Left /Right target?

Th is DOES NOT count as a win for you. You MUST land the killing blow yourself—you wuss.

If a player has the Strength in Numbers Win Condition and gets 35 or more troops during the troop placement phase, do they still win if Pestilence occurs?

Yes. A player wins the game as soon as any valid win condition is triggered. The faction would win during Phase 2: Place Reinforcement Troops.
