Icy Avalanche is a Warframe Augment Mod for Frost that grants allies within the radius a protective coating of ice for each enemy that is frozen by Avalanche. At base, the amount of damage they capture per enemy hit is 60, which is moddable with strength.
Sounds good right? Was quite excited myself when I first discovered this mod as one of the only 6 Frost players out there. Jokes aside, I've got to say the augment is good, for enemy levels under level 50. The Ice coat health you get has no damage reduction to it (Adaptation does not reduce the damage it takes either) and it's also not affected by armor, which is one of Frost's main stats as it also affects his globe. It gets shredded easily and just one look from a SP corrupted heavy gunner and its like the ice coat wasn't even there to begin with. What I'm saying is that this augment could be a lot better, either straight up increase numbers, letting it be affected by armor, providing a grace period of invulnerability like when you lose a Mesmer skin charge, etc.
or
Make it similar to Mesmer skin. Where each enemy hit by Avalanche would give 1 charge of mesmer skin/ice coat. Along with the grace period it also gets per charge depleted. But what if there are no enemies around? Provide it some base Ice coat charges affected by Armor (This way you have another good reason to build armor on Frost). Each charge would be an equivalent of 100 armor. Frost Prime has 300 Armor so therefore he would only have like 3 base charges of Ice coat and the other charges you'd get from hitting enemies with avalanche. Of course there would be concerns that like Mesmer skin, its just free invulnerability. So I would suggest a cap of charges you can get from avalanching enemies but no cap on how much base charges you can have (though if too unbalalanced, may cap charges from 1500 armor?). For example, Hitting around 20 enemies with avalanche but the fixed max ice coat charges you can get could be 10-12 (or maybe less?).
Thats my take on how Icy Avalanche can be improved. I would appreciate the feedback on how to improve, what to change, and of course you're also free to disagree. Thank you!
