Intense damage and very high damage resistance. WARNING:low max energy build. Zenurik is recommended for this.
First ability: Can replace 1 with whatever helminth ability you would like, however most abilities require better duration.
Second ability: will always want to keep this active. This ability used with [Adaptation], she takes most of the punishment thrown her way. Also use your third ability to disapate some of [Ember]'s meter, or toggle on and off once meter is almost full. Then quickly reactivate. This avoids draining all of your energy very quickly. Energy cost wise, it is more effective to toggle on and off this ability.
Third ability: amazing CC and armor srtip. Primarily used for steel path or any enemies over level 100. Also will drain heat meter, but strips more of the enemies armor the more full the meter.
Fourth ability: spam this one. Should be able to kill most of anything with the double proc heat DOT. (Pre level 100)
Most used combo: Triggering your third ability will stack into [Ember]'s passive and strip armor. Making enemies more susceptible to heat damage and increasing [Ember]'s ability power (temporarily). Then use the fourth ability. Both abilities will proc their heat status for double, because of [Archon Vitality]
Archon shards: recommend to have two amber shards to increase energy ord effectiveness by 100%. The rest are up to you. Some extra ability strength or energy max could be very useful, depending on your play style.
