Apologies for appearing angry - I was just annoyed as the relic showed up in my relic pool - maybe some relics tied to increased relic odds/loot #/options?
And to be fair, I didn't realize you could click on things to check the stats of the unit... I was wondering why the game was so hard, as I didn't know what the topaz mines and the shards were/did... nor did I know that you could level up towers... -_-
That might be the reason :p, you can upgrade units too - by clicking on the tent. Soon I'll release metaprogression part of the game, lots of balancing changes (including frostbolt buff).
