Well I have actually found 1 item which was a speed item which has no use to me at the moment because 1 I have no monster to give the item to and 2 I am unable to move my monster even if I had one as I’m a mobile user.
I search the forest around 10 times a day so I’d say that I have a fairly decent chance to find a monster/egg soon.
1. Well, you can sell or forge it, till you got a monster, to equip it.
2. I've added a possibility to move your monster even on mobile (Theres a control pad under the canvas). But its not perfect, cause, well the game was designed to be a PC-Game, i am sorry.
