I now know to never use double-clicking to go down stairs, at least in Gaan-Telet. Accidentally triple-clicked right onto a level 9 dragon while at low health. This especially deserves to be there since this is the third perfectly good Gaan-Telet Assassin run I've squandered in a row, specifically on the second floor due to a silly mistake; the other two times were caused by temporarily forgetting about the Retaliate:Fireball effect.
I think the game really doesn't want me to beat the place with an assassin... (it's just regular Gaan-Telet. I shouldn't be dying so much XD)
