Raal is a hovering pig fixed in one location so you won't need to be chasing him round the room. The tank simply needs to keep aggro as the others take out the pig. To make sure that people don't just stand in one place, Raal will occasionally be sick, both at a random character and a large area in front of him. Although listed as the third character to engage, he can more often than not depending on your route be the first to be encountered.
These two are situated in the cellar, just before the final boss. When you approach them, they'll be a barrier preventing you from getting at the them. When the fight starts, the Lord will jump across and attack you. When the Lord comes over, simply attack him, leave the Lady alone for the moment.
As the fight progresses, Lady will heal at the deteriment of her own health the Lord. You need to keep targetting the Lord as when he dies, the Lady's health goes down as she resses him. A ranged can attack the Lady but melee should always stay on the Lord. The Lady when he health is low will fly over and attack though.
