Here is a vid to show the synergy between PoA(Pole of Agony) and Reversi:

Description:
When Mobs stand on top of the PoA they take continuous damage, If a certain Attribute is levelled/brought, then the mobs will also take further continuous damage once they run out of the PoA.
Normally, the mobs wont take both the PoA’s initial continuous damage and leaving penalty continuous damage at the same time. However with Reversi Skill Scrolls, this is now possible.
By using a Reversi scroll right after u cast PoA, this makes the game create a new instance of PoA with the same timer as the one you just casted. This technically makes the mobs “Leave” the old PoA and therefore they suffer from the leaving Penalty Continuous damage AS WELL AS the “new” PoA skill damage.
This is just a trick that can be used with PoA that some people may or may not know to help increase their damage.
Some estimated(?) damage numbers are:
normal PoA damage = close to 1 mil
PoA + Reversi = close to 1.5~2ish mil
PoA + PoA scroll + Reversi = close to 3ish mil (I think the Leave Penalty DoT damage doesnt stack here(?))
(Note: Damage numbers are very roughly estimated as if you noticed i sometimes sp potted either not enough times or too early/late in the vid to proc chap cards)
Reversi Skill Scrolls can be brought off the AH/Market as well as PoA Skill Scrolls. these scrolls are created by the Enchanter class which allows them to make the scrolls and sell/use.
