Unless you are using stealing Inquisitor's Inevitable Judgement via Forbidden Flesh/Flame, this is probably the single biggest damage upgrade you can make against Lycia, who has 50% elemental res. Most builds I see either have 0 investment in reducing or penetrating this, or use Frostbite, which tends to be less effective than Elemental Weakness WITHOUT Balance of Terror with a Heatshiver at only 15% chill effect and no freeze.

Whispers of Doom, to slot the extra curse, is 4 points away from pretty much all of these builds, as they take Influence. The vast majority of these builds also have a jewel slot within 2-3 points, or can replace a jewel of lesser value for the Balance of Terror itself.

The obvious downside is that you have to selfcast the curse and cannot link it to Arcanist Brand, but is well worth the effort on anything that doesn't get onetapped.

Here are a bunch of examples taking builds from this subreddit, and adding this combo (35% BoT, 20/20 Elemental Weakness:
