They both apparently drink liquids too it ' s so obvious why couldn ' t we have seen this sooner <| sep |> Yesss . Girls who rock it have my heart . <| sep |> Underbelly weakeness is something nobody knew until the last minute and even then it was extremely difficult to hit the spot , making it very unlikely for Geralt to hit it or find it . Assuming that he finds it and somehow hits it , he is going to make Smaug panic and go crazy with the fire , killing Geralt too . Wizard help is kinda cheating because it would not be Geralt vs Smaug , it would be Wizard x vs Smaug . Also dragons have definitely some magic thing going on with them on Tolkien , both Glaurung and Smaug showed some abilites like really lowtier mind control for Smaug and midtier for Glarung and some kinda of sixth sense on feeling people around them . For the bombs to work they need to be strong enough to onehitkill Smaug but not strong enough to collapese the chamber they are in , which is very unlikely . Poison may work , but how are you going to poison Smaugh ? , he does not eat regularly and eats people , so you are going to need to put poison on living people with enough strenght to kill dragons , something that is probably not possible , and gas poison on a closed mountain you are begging to be killed . 0 prep Geralt has now chance , and even iwth prep is very unlikely not to mention that it is very difficult to find accurate information on Smaug unless you talk to Dwarves that were there most of them dead , Elves If they allow him to talk to them or some of the humans that barely see Smaug when he hunts .
