Masters

You hire masters in the gold menu on the Premium page, in the Master builders tab. Each master covers your whole account in that world and runs for 30, 90, 180 or 360 days – longer terms are much cheaper per day.

Building master

The building master upgrades your castles while you are away. In the Construction office you set, for each building, the level he should build up to and what percentage of your resources he may use. If you tick demolish, he instead tears the building down level by level to the level you entered – level 0 removes the building and frees its build field. He looks after up to 10 castles of your choice, and the construction office shows when he last visited. Price: 40 gold for 30 days, 90 for 90 days, 170 for 180 days, 320 for 360 days.

Troop master

The troop master recruits automatically. In the Barracks, the Stables and the Catapult workshop you enter how many of each unit he should train, then switch on automatic recruiting. He stops as soon as the target is reached or your castle has no free population left. He also looks after up to 10 castles and costs the same as the building master.

Trade master and guard master

The trade master sends your traders back and forth on fixed routes between two castles – even if the starting castle is a little short of resources at the moment. He has 30 route slots, and every planned route takes 1 hour longer than a normal delivery. On top of that, the raw material exchange at the market becomes free for you, and on the amber page of every castle you can swap one type of amber for another: you get half of it back and must put in at least 2 amber (Traders and routes, Amber). Price: 100 gold for 30 days, 280 for 90 days, 520 for 180 days, 960 for 360 days.

The guard master takes care of your knights: automatic sign-up for the daily tournament, 25% more fame from the tournament (not counted for rankings), 10% more experience from missions, a higher chance of items and access to the thaler shop. He costs the same as the building master. Everything else: Guard Master.

Elite masters

The building, troop and trade masters also come as Elite. You buy Elite on top of a running master, and the Elite duration has to fit into that master's remaining time – otherwise the shop tells you the base master has too little time left. The Elite building master and Elite troop master cost 60, 135, 255 or 482 gold, the Elite trade master 60, 167, 313 or 576 gold (for 30, 90, 180 or 360 days).

• Elite building master and Elite troop master also work in gold and event castles (such as Baldur's Fortresses) and look after 10 more castles. The Elite troop master can also fill the queues there with the 3-gold option.
• Elite trade master also runs gem trade routes, adds 30 extra route slots and +25% treasury capacity (calculated on the base values). When swapping amber you get 80% back instead of 50%, with a minimum of 5 amber.
