Screw the hall of the dead, the best miracle attack can be set up in the 2nd cave of trials level.(note: you need to be towards the end of the games for this.) The easiest way to set this one up is to quickly look around the stage when you first enter it and check to see if any of the dark portals start at the outline of the level. If none of the portals are on the edges you can set this attack up just like the hall of the dead level. If you do have a portal on the edge of the screen, the only way this works is if it is a red colored portal. Now the set-up can get very tricky if you do not have the warp engine(postioning your players can be difficult without killing the enemies on counterattacks) Start by equipping Prier with the warp engine and move her within purifying range of a red dark portal.(If it is on the edge of the map,place her on top of it) Next place 4 characters on the 4 corners of the map(using the warp engine). Now take a minute and use one change-up to redirect all the dark portals so they are pointing towards the edges of the map,close enough so that the 4 corner players can use change-ups to redirect currents. Redirect all the portal currents except for one red portal.(this is critical). After doing this you will probably have 1 or 2 characters left to bring out.Use these characters to redirect the remaining red portal into itself. Finally have Prier(or whoever has the equipment you want to level up) purify the red dark portal that she is on or near (not the one that is directed on itself). By doing this, you end up getting a quad miracle attack (1 holy & 3 healing). Averaging around 8000-10000 bonus points every timeSometimes you do get unlucky and only get a tri-miracle attack, but that's still worth something like 6500 bonus points. Once you get use to doing this, the whole attack can be set up within a few minutes( the longest part is actually watching the attack take effect).
