NPC/A6/HB3

To build ballistae, you need a minimum or archery level 6. (You can get ballistae with a mechanics betallion, via the wheel, but this is not worth documenting.) To build Transporters, you curiously don't need horseback riding, even though transport speed is directly related to your HB level. Weird. But you do need metal casting 3, and building cavalry come long before ballistae, so having at least HB 3 is very likely.


 * Too few ballistae for level 1 will often result in a total loss of troops! So when possible, be a bit conservative. With the other city levels, you might lose a few ballistae, or lose the battle (100 round defeat) but keep the troops.
 * The above results will vary due to the defending city's hero. If there is any doubt, scout the city and if there is a hero, add to your balistae force (as a guess) 20% plus 1% times the level of the city's hero.
 * A "+" means "at least this many" -- that is, the attack linked to failed without losses.
 * A '-' means it might be possible to use fewer ballistae than reported so far.
 * A "/" followed by a number is the number of lost (destroyed) ballistae due to the battle.
 * Don't bother with Level 6. You'll lose lots of troops AND your loot will be only 133% of a Level 5 city.
