I guess I would describe myself as an intermediate player.
I just tried the goblin assassin at Havendale Bridge. I actually did quite well, had 3 enemy left, and the boss, and no more unexplored tiles. For a minute I didn't think I'd be able to beat the boss and actually considered retiring, luckily I was worshiping Dracul, and killed two level 1's and got extra health with lifesteal. Then was actually able to hit the boss, then converted the sensory stone to level up, Kept hitting the boss with fire ball,till I used up all my mana potions, attacked him, used my health potions to get back to take a hit, then did that again, and lastly I used Blood Swell. I feel so accomplished.
Edit: Oh and did I mention, I was only trying the dungeon for the first time, so I didn't even use any preps.
