If you're in the Sparyard of Scant Mercy speed is your friend more than stealth. Also, using Dragon's Glaze is a bad idea because Frostwyrms are strong against Frost Attacks. Using Revenant Wail+Blast Arrows aimed at the head from the balcony at the bottom of the stairs should be enough to interrupt the first cast as long as his buddy hasn't also started casting on you. Barbed Nails help with interrupting his spells if you're still having trouble.

Once you know the room has two Frostwyrms, be sure to enter the nearby riftstone to lock in the spawn. When you exit from the rift if the spawn has changed then just reload from last checkpoint and you should get the 2 Frostwyrms back and you can keep reloading from last checkpoint until you get the timing/strategy down.

Once you've mastered the 2 Frostwyrm combo, you can try the Frostwyrm/Firedrake combo, but that will be harder and switching to Dragon's Glaze after defeating the Frostwyrm might offset some of the damage loss from using blast arrows on the Fire resistant Firedrake.
