Like, in Blackwood, you have to pass through three islands before you get to the centre.
- (1) the starter island is one of three, and contains no miniboss
- (2) then there is another island which contains a miniboss
- (3) then there is a third island which contains a miniboss, guarding the door to the central area
- (4) then there is, finally, the central area, with its hidden miniboss and the actual boss.
So...
What determines which minibosses can appear on (2) and (3)? I'm trying to complete the achievement for killing all the bosses in the oblivion portals but there is one which just doesn't want to show, and is there a way to make it appear, or go to where it is?
Are the minibosses tied to specific locations?
Is it possible to kill one, wait for a respawn, and have a different miniboss respawn there instead?
