This is one of the new defensive legendary gems that many of you guys insisted would never be worth using. The gem is [wiki]Esoteric Alteration[/wiki] which provides a full time resistance buff to all non-physical damage types, and at rank 25 tacks on a giant 75% damage reduction when you drop below 50% life.
The video is useful though, since he shows how his toughness and resistances are jumping up when he equips the gear, and the bigger jump that goes when he drops below half health. Legendary Gem Video Tutorial: Esoteric Alteration:
Note that the gem’s defensive bonuses apply only to non-physical damage, which means all of the dangerous [wiki]Elite Modifiers[/wiki] like [wiki]Arcane Enchanted[/wiki], [wiki]Frozen[/wiki], [wiki]Molten[/wiki], etc… but it won’t help against the few physical attacks, such as when Mallet Lords judge you harshly by dropping the gavel. Player skill is thus required to get the full benefit from this gem, and it’s going to be more useful for non-melee characters, who can generally stay back out of hand-to-claw range.
I might actually give this one a try next season on Hardcore, though the real killing danger of something like being Vortexed into a Mallet smash just as four Moltens blow… would probably still prove lethal. Anyone else curious to try it out? Any rethinking of your defensive LGem prejudices?
