To `impy` you put 2 things in opposite to yourself in tread name :
5) no pet dragon usage throughout the game. He stays at level 1.
And later in same post you type :

Do not get tempted to buy much else than creatures, you will not have dragon for digging. I was running around with training buckler & sword until 15 levelī.
How can you leave pet dragon on 1 lvl , if you use him (or her, i`m not sure) for diging for chests +7% more xp medal. Dragon will get some exp form if for sure, therefore geting lvls.
I agree that game can get tedious after couple time playing it, trying diferent tactics can get chalanging for some time. But this ultimate chalange simply contradicts itself.
How about this then , ultimate chalange.
Rules : 1) Use only peasents
2) no more rules . . .
Game makers made diferences between warrior and mage in pet dragon/magic. Playing warrior and not using dragon seems pointles to me, but that`s just my oppinion.
I hope they`ll make some kind of multiplayer for this awsome game, or at least something similar, cause AI just isnt interesting. Anyway play for fun ppl
