When I get to the room with four guards to take care of, I died the first time and now can't deal damage to any of them. The spells just don't do anything. Any tips?

Its a bug, are you playing the Android?

PC

The spell dont do any damage, you have 2 spells, Strip and Lust. Strip take out the clothes and Lust make susceptible for sex.

Pressing Q you will cast Strip and pressing 1 you will cast Lust, than you can make sex with the target pressing enter
