Using assassins for expansion

[Gandalf Parker]

If I remember, the era also makes a difference.
In era 1 you are more likely to run into barbarian commanders, and indie mages?
Its more effective in era 3 games where a single commander is usually an armored one, and likely to be leading larger groups of troops.

I use assassins to aid expansion in some games, especially as abysia. If you aren't running sacreds, prophetising a starting assassin works a charm. Definitely focus your assassins on the tougher opponents, saving your troops

I'd say be save and just use a group of 3 assasins and a scout. 3x assassinate then take it with the scout and keep moving Having said that I think it'll be slower than regular expansion since it takes more turns. Also loosing an assasin can be more expensive than just loosing 1-2 troops each province.
