I'm afraid not all of my questions are simple but it seems like a great thread to post them.
1) what is the exact amount of

pracinhas generate in battle? In one thread I saw a number 100, but the manual also says that the amount is doubled in foreign lands, so I'm not sure is this 50/100 or 100/200 (in your lands/in foreign ones) or something else
2) can Venice buy tiles in puppets?
3) the siege tower has "extra sight 1" promotion while the catapult has "sight penalty" promotion. The question is, do the ST keep their promotion after upgrade? Trebuchets with sight =3 would be great
4) how exactly does ikanda works? As far as I understood it's:
-build an ikanda
-build a unit in that city
-upon being built the unit has a unique promotion amongst the standart ones (like shock and drill). Is this randomly one of the three or always, say, buffalo chest?
-if you choose a unique one, at the next promotion you can choose amongst insta-heal, shock1, drill1 and another unique (again, random one or a determined one?)
Am I right?
5) does the zulu unique promotions and army maintenance reduction works on gunpowder (melee) units or only pre-renaissance ones?
6) their is not a single word in civilopedia nor manual about kasbah having defensive bonus. But it is here, right?
7) from manual: "<chateau> gains +1 culture and +2 gold upon researching Flight, as well as the +50% defense bonus on the improved tile". Does it mean it has a defence bonus only after Flight? Where is a logic in that? Or is it just a bad wording?
8) what is exact Shoshone friendly territory

bonus in% ?
9) comanche riders. 25

cheaper and +1

promotion (so it can be saved after upgrading). Is that really all? If true, that sucks. Maybe that promotion leads to high-level ones like blitz or charge quicker or something else?
My sincere thanks if somebody can answer those questions!
