I have played the Tinker a few times now.
I have noticed that Drogons experiences a drop in attack after he has chosen the Beast-skill. The beast substracts 50% from his attack. If he normally would have 10 attack, the Beast-skill substracts 5 from the attack - with a final attack value of 5. I do not hope this is working as intended.
Further the Tinker's skill tree is very nice. However the skills that provide extra spells to be cast on items do not work. I started with 8 spells (+2 attack, +2 lighting attack, +2 defense etc.) and I still only had 8 spells after choosing the skill providing extra spells (one the upper skills toward the right). I do not know if must research them first, if yes - it should be more clearly stated.
Another thing I would like to see changed. The amulet giving extra spell casting in combat, could this be changed to be a consumable item, giving a permanent increase. This could be balanced by requiring very rare (legendary) ingredients even though Radiant Diamonds seems to be pretty rare in itself.
