the doors are locked by a bar; you'll need to destroy the bar by the sword of light. the best way to do it is to shoot fire-spitting demons on the left and right and to kill one of the walking demons. let the one on the very top still spit fire balls; if you kill him, all three fire-spitters will be re-generated. it's easier to hide from him then from the two others. one walking demon is also necessary to prevent regeneration of two such beasts, so just run from him while waiting for your mana to restore for another hit at the door bar.
