Esoteric Alteration
Legendary Gem
Properties:
Chuanyang of Xiansai designed a gem which would transport magical energies from their target to the workshop of his greatest competitor, Chau Thanh. He created several copies of this gem before he mysteriously disappeared.
Notes[]
- The damage reduced is any Elemental Damage type except Physical.
- Damage reduction is multiplicative to other similar modifiers; resistance bonus stacks directly to other similar enhancements.
Tips[]
- As most Physical attacks are melee, this gem may be especially useful to ranged classes, who are generally not engaging in close combat either way.
Trivia[]
- This is one of the five gems (the others being Molten Wildebeest's Gizzard, Mutilation Guard, Invigorating Gemstone and Moratorium) that offer defensive, rather than offensive, bonuses.
History[]
- This gem was Season Two-exclusive, but once this season ended, started to drop for normal characters as well.
