Trollworld Sentinels 7
From Xhodon 2
Attacking Sentinels
Attacking sentinels will not earn your hero experience for killed sentinel creatures. Only your own casualties will give some experience.
To slay sentinels of level 7, in one round a minimum of about 68'000'000 Goblins (or creatures of equivalent strength) is required. To kill the sentinel in two rounds you need around 34'000'000.
You will need up to 52'000 Unicorn Carts to carry the loot.
Defending Sentinels
To defend a sentinel, move a hero to its valley and set his defence status to "Valley defence". Setting the defence status to "Area defence" will not defend sentinels as they do not count as allied units.
Example Sentinel
Other Sentinels level 7 may be stronger or weaker. Accordingly, they leave more of less loot for you.
