Is there any way someone could tell me the calculation that gets used for determining damage dealt to the player? It had assumed at first, that if the armor any resistance to the particular damage type received, then the armor would be ignored, but if that's true, then there is a massive problem.
Consider, that because enemies in tier 1 only do normal damage, and the Divine mantle has elemental and shadow resistance, but no normal, then you'd be better off wearing your starter armor, then that particular 5* armor if you were in the lowest levels.
Likewise; Heavy Plate mail, a 4* armor, has only normal resistance, and so would be useless in the 6th strata, where enemies no longer deal normal damage.
This seems like a huge oversight, and i would really appreciate it if someone could alleviate my fears.
Assuming you're doing t3 Elite, many melee attacks still do normal damage, while a lot of projectiles do pure specialized damage. Stand in front of a Trojan sword slam and you'll get a ton of Normal Damage and no Shadow, Lumbers and Thwackers will do split Normal and Elemental, and turrets will simply laugh at Plate Armor with their pure Elemental, Shadow or Piercing, depending on the turret.
Also, in the deeper t1 depths on Elite, many enemies start doing split damage. Just ask my Heater Shield (Normal+Elemental+Freeze), which doesn't last as long against the Snarbolax compared to 2* and 3* Defenders (Normal+Piercing), in spite of its 5 stars worth of Normal defense.
As for actual mathematical calculations..... Well, that'll just make my head hurt. Either way, it boils down to looking at the damage bars that pop out when you get hit by an attack.
