So is Dracul 2 impossible or what? Converting the HP potion and using 2 fireballs on the wraith seem to be the only viable way to reach level 2 without being dropped to 1 HP. This at most allows you to hit the dragon one time before leveling, and after that it doesn't seem to matter which boon you take but you can only take one no matter what (Blood Swell is the one that gets the best result for me).
The best I can do is get the dragon down to 6 HP. If it was possible to conserve the mana potion until level 2 then it would be doable, but that's impossible because you can't kill the wraith without using either it or the health potion + some boon (which requires taking Blood Curse too early).
I noticed that we start with 25 gold in this puzzle, which is completely useless. Was that supposed to be Piety?
(or not, since it seems that's not the only puzzle that gives you gold to start)
