9-10 is what I'd recommend.
ups no wonder my first time fighting was hard i fought it at lv 7
I'd actually recommend fighting it at level 12-13 so that you're able to tank multiple hits, also make sure to defend when the game says that the minotaur is preparing something big
Really? I'm died when have in 12 lvl … Why? It's very simple, just read the FUCKING TEXT!
