Purity of Lightning is an aura that grants lightning resistance to the caster and his allies.

Skill Functions and Interactions

Both the additional lightning resistance and additional maximum lightning resistance are affected by increased aura effect.

The following x% increase in aura effect are needed to recieve a higher amount of max resistances. +5% max resistance are gained by a lvl 23 version of the aura.

Aura Bonus/ Actual Bonus	+5% max	+6% max	+7% max	+8% max	+9% max	+10% max	+11% max	+12% max	+13% max
+4% max	25%	50%	75%	100%	125%	150%	N/A	N/A	N/A
+5% max	0%	20%	40%	60%	80%	100%	120%	140%	160%

The passive tree can provide 69% aura effect which requires heavy point investment though. The Guardian Templar class can have an additional 10% effect and the Champion Duelist class an additional 5%. Conqueror's Potency can provide another 3% effect.

Through the use of Victario's Influence with its lvl 30 Generosity Support and up to 15% effect mod, an additional 64% increased aura effect can be obtained. However, supported auras will not affect you.

If the player equips a Dying Breath, an additional 18% effect can be achieved at the cost of a shield (such as Prism Guardian) and weapon (such as Advancing Fortress or Ephemeral Edge)

All this sums up to a maximum effect of 154% for non Champion/Guardian, 159% for Champion and 164% for Guardian.

See the aura page for more details.
