That point was her last battle, so claiming she's not Saint Wizzard level is not cutting it. Also Deliora is stronger than Lullaby which blasted a hill away easily with a mouth blast and Deliora 's own laser has an AoE on par with Natsu's LFDR back in Tenrou island. It's not an exaggeration to say she's Saint Wizzard level.

Deliora is above PTS Natsu going by the feats within manga and anime and also above Erza. Just a roar from Deliora at it's deathbed shook the island, hardly much different from Gildarts weighing down Natsu with his raw magic power.

The laser generated heat, deflecting it with an ice shield shouldn't even be possible and  not something that can be easily done.
