Azrael

So you need primal flame as the only weapon (spike shield, fire ring) until after the fist mini boss (stage4) otherwise the spikes are gonna hurt too much. So buy as much healing items and defensive items as possible without any weapons that could get you hit back by spikes. After that you juste need to stack your own spikes for the second boss and add a fire weapon if possible here. And get as much Supression/Absorbption collar as possible to prepare for the last boss. Good luck
