Ring of the Combines is not available
 

Roule has the druid group port but the single port he has is the wiz one. The wiz one should be at the merchant in Temp Sol Ro, not on Roule. The merchant listed to be in Gfay with this spell does not exist in game.

He actually has both group versions, not the single one.

There is still no single port for DL. It was released later
