"After senatus level 30 you can entrust businessmen in the armory and have a chance to get world's top horses and shields."There are two options.
Shields - pay 10,000 silver and get a green or blue named shield. Those vary in value from 7K to 30K (sell value 3.5K to 15K). You also get a chance of getting a higher level dealer which grant can grant you a higher level item, at a higher price.
For each time you click entrust you pay the silver and get 10 minutes cooldown time added, at 1 hour it locks to full cooldown.
At the highest level you pay 60,000 silver for each part (randomly granted).
Horses - You pay 8K silver and get green or blue named horses. Value varying from 7K to 24K (sell value 3.5K to 12K). Also a chance on getting to a higher level dealer. The highest two tiers here only sell items for levels 55 - 90 heroes and only sell parts (1/5, 1/10 and 1/20).
At the highest level for horses you pay 46,000 silver for each part (randomly selected).
