Holy Ruins (Poison Map) - Final Boss

[mephisto009]

Any hints where the final boss is for this location? I've found four rooms that require triggering mechanisms (including one that you have to break a wall - new to me), and found two of three portal parts (1 and 2). I can't think of what I'm missing for the portal part 3, as well as the final boss (which I can see from a higher level, but can't figure out how to get to it - other than just dropping down).

If you go around that upper balcony where you can see the boss, there should be side passages. Look for a passage that has two other passages inside it, one sloping up and one sloping down. The one that slopes down should lead you to the boss eventually, if I am remembering correctly.
