Elemental Armor is a premium armor that boosts the damage of elemental perks (Ice, Zap, Poison, Fire, and their improved versions; possibly also Dr. Toxic’s Venom, Mortis’ Plague Cloud, Fursus’ Iceplosion and Arctor’s Freeze)
The boost depends on the rarity of the armor:
| Rarity | Bonus |
|---|---|
| Common | 20% |
| Uncommon | 25% |
| Rare | 30% |
| Epic | 35% |
| Legendary | 40% |
| Mythical | 45% |
| Exalted | 50% |
| Deluxe | 55% |
Maybe it works also with Mortis and Fursus ability?
I think it will work for them and Arctor’s Freeze. Not able to test it myself 
but would appreciate if someone can test it and report back (very easy to check - record a few rooms with and without the armour and see if the elemental damage numbers are boosted). A slow gun like Laser Rifle is best as there’s less clutter
The best is that the elemental damage is colored… Red for fire green for poison purple for electro and blu or light blue for ice damage… So u can see it clear on the screen
I think that’s a great idea and made a post here.
I would suggest you send it in as feedback to LH directly as well (in the past they gave out rewards for suggestions they liked; not sure if they still do that 
)
