As it is right now we have fortune wheel that uses one of the most valuable resource in the game and it produces rewards that arent usually worth anything. Yet that space could be used better in my opinion. So here is my suggestion.. We replace wheel with in game calendar. That calendar would have 20x13 days and each day would produce luck rewards or events.
Luck rewards are very much the same they are now. You can get them during those days that dosent have any events on. What has changed is that now you should be able to chose what you sacrifice. Is it a soldier (after this action it cannot be healed), amber stone, 250 turquoise or loot.
If you sacrifice soldier. You may get bonuses like 5%-30% Wall bonus, 5-30% stamina 5-30% army speed or anything related to army and warfare. Sacrificed unit determines how large or how long bonus is active. If you get 5%wall bonus with EK unit. It could last 65 days, but with spy unit it could last 2h.. If you have very good luck you might get 1-20 nahuals/amazons.
Sacrificing amber :
If you sacrifice amber you may get builder and tech bonuses. More amber you sacrifice better the bonuses can be or their duration can be longer. At one go you can sacrifice max 5 ambers. There could also be rewards like random free tech/building.
You can sacrifice 250 turquoise and win shop items. Some cheaper than they are in shop and some more expensive.
If you chose to sacrifice loot. Then you will get random target that you are to attack. Random towns are selected from towns that arent in same tribe, close proximity and roughly the same lvl.Owner of that city gets a warning that someone has been guided by wrathful gods to attack his/hers city. After that you have end of that day to attack that city. More loot and troops you kill. Better the reward you may get from Tzolks calendar. If player dosent attack selected town then he may get punished by gods. That punishment could be -10% to -50% stamina.. or some other negative bonus punishment. Duration is rest of the calendar month.
If how ever target town is empty. No troops and no ress. Then defender may get punished by gods. Even if there is something little to steal defender might still suffer. That is the case if defender is larger than attacker.
Rewards from this event are always good.
All the battles get ranked in def and attack lists. If your attack ranks high on either list. Then its possible to gain bonus reward that effects whole tribe. Every unit and resource is turned into points. After the attack. What resources you might have stolen are lost to gods..
When ever there is events like Research faster! or crystal event. Luck rewards cannot be collected. However. From now on we can see when these events will be on. So we can prepare for them. The Bacabs' Crystals event could now show itself more often, but in shorter periods. Like 7 days per month. Events could be divide in 2 categories 3 day events and 7 day events. Right now only The Bacabs' Crystals event is 7 day event, but in future could be more.
What do you think.. ?
I note that change could be made much simpler too and if final result would be simpler. It still would be large improvement.
