So what am I doing wrong in NOT getting any of these? Is it worth me having a ToR? I am on battle 12 on level 1 and yet NOT found a Relic. Yet when I first got the ToR I may of found 3 on the first level.
If you believe in things like "good luck" or "bad luck" then these things won't matter to you but
here is where you can see what the relics give and
here is where you can see more info including some data on what the % is on getting relics and %'s on getting goods from relics, 16% and 18% respectively for Common and Uncommon relics but that is based on user generated info not Inno but it's probably close to the reality anyway.
So say you have a level 1 ToR, it gives you a 12% chance at each encounter to get a relic. So let's say you do 48 encounters. Over a long period of time, say a year, you should be close to getting an average over that year to about 6 relics per week. This doesn't mean you will get 6 per week, you might get less, you might get more but in the long run will average out to about 6.
So let's say you get 6. Now out of the 6 there's a 75% chance it will be a Common Relic or about 5 relics on average. 1 will be uncommon on average and over a long period sometimes you'll get a rare(Jade) relic which is a 1% chance. So then out of the 5 Common relics you get an average of 18% which means on average 1 out of the 5 will give 20 goods. Then 16% for Uncommon relics to give 200 goods which means since you're only going to average one a week and say you do get one a week then in a year you'll average 8(200) goods wins.
Whether or not ToR is worth it is like every other building in the game, if you find value in it then it's worth it to you.
