Which castle can’t be taken by a Necropolis on day 111?

But wouldn't sacrificing half your army for a bit of gold to improve the overall situation? :rolleyes:

Actually, I want to teach people ;)
Show them what can and cannot be done. As we've already seen, Rampart, Tower, and Conflux can be easily taken without sacrificing half the army, or even losing any units at all.
And a little gold – that's 5K – can be used to buy two extra heroes, for example, which is especially useful on Jebel, where you need to split 8 heroes on day 111 ;)
