Gain 15% of Maximum Life as Extra Maximum Energy Shield
All Damage taken bypasses Energy Shield
50% of Elemental Damage taken as Chaos Damage
+5% to maximum Chaos Resistance
Energy Shield Recharge instead applies to Life
When you reach full Energy Shield, Sacrifice all Energy Shield to gain +5% to all Maximum Resistances for 4 seconds
Energy Shield starts at zero
Cannot Recharge or Regenerate Energy Shield
Lose 5% of Energy Shield per second
Life Leech effects are not removed at Full Life
Life Leech effects Recover Energy Shield instead while on Full Life
Total Recovery per second from Life Leech is doubled
You have no Life Regeneration
Damage taken as - Mahuxotl's Machination grants Divine Flesh. When combined with Tempered by War, no lightning or cold damage is taken, making it ideal to combine with it. Half of the damage is taken as fire and the other as chaos. This allows the player to completely ignore gearing for Cold or Lightning resistances. See Damage taken as for more information.
Life Recharge - Vaal Discipline will immediately cause Life Recharge to begin and prevent it from being interrupted. Wicked Ward also works; however, it will reduce the Recharge Rate by 40%.

Maintaining Everlasting Sacrifice
To maintain full uptime of the +5% to all Maximum Resistances, the player's energy shield must reach full at least once every 4 seconds (after which it is sacrificed by the Keystone). Due to the interactions between keystones, it is not possible to regenerate or recharge ES, meaning that instant recovery and leech are the only realistic strategies. The 5% ES degeneration per second must also be overcome if the player cannot fill the entire ES pool in one instance, combining up to 120% of their total ES over 4 seconds.
