Naturally, Izroth was well aware of how bold his statement may seem to others. However, he had something no one else in the Mortal Realm possessed—the Elixir of Immortality.
Of course, the Elixir of Immortality was only a last resort if all else failed. After all, the effects of the elixir was something that a price could not be placed on.
Nevertheless, in the end, while it would be shame to lose such a valuable item, in Izroth's eyes, it was just that—an item. In the future, he would have multiple chances to come across items just as good or perhaps even better than the Elixir of Immortality. That's why, compared to saving Nova, it was not that big of a price to pay.
That being said, Izroth also had no intention of relying on the Elixir of Immortality to cure Nova. He had something else in mind that was only possible now that he had Nature's Preservation along with all materials stored within from Franz's garden.
