No-Cp Skirmisher MagSorc - Sorcerer Construye PvP - ESO

In-between each ability you should be weaving light attacks, if you don't know what that means, it is light attacking before casting every ability. It helps generate ultimate, proc enchants/poison and keep pressure on the opponent.

Buff Rotation: Hardened Ward → Critical Surge → Elemental Susceptibility → Haunting Curse → Dark Conversion → Hardened Ward

Explanation: This is straight forward. Although you only need to use the 1st Ward if you are rebuffing in combat. and popping curse in buff rotation just sets up your burst better

Burst: Haunting Curse → Crushing Shock → Hardened Ward → Streak → Crystal Fragments → Streak → Hardened Ward

Explanation: On your back bar pop Haunting Curse the switch and use a Crushing and Ward then Streak the target to stun them by now you should have an instant cast Frag and while they are stunned hit them with it and curse will blow up at the same time. then Streak again and Ward to disengage to safety.

Burst using Ice Comet: Haunting Curse → Crushing Shock → Hardened Ward → Ice Comet → Streak → Crystal Fragments → Streak → Hardened Ward

Burst using Power Overload: Power Overload is easy to use all it does is become your new light attack and if you are weaving attacks like you should be nothing changes from popping this but the target taking more damage. You simply use Power Overload before your burst and that's it.

Power Overload should be up most of the time when bursting someone and yes it is possible to use Power Overload and Ice Comet at the same time but it takes practice I'll show you the rotation:

Power Overload → Haunting Curse → Crushing Shock → Hardened Ward → Ice Comet → Streak → Crystal Fragments → Streak → Hardened Ward
This will kill pretty much anyone requires exactly 233 ultimate. 21 per for 3 weaves of Overload and 170 for Comet.

Healing: Hardened Ward → Dodge Roll/Swap → Potion → Dark Conversion → Harden Ward

Explanation: This is for when you are low on health, using Ward for the 1st time ensures you don't die from execute or anything else, you need to animation cancel this by Dodge rolling or Swap bars(Only dodge if under attack). Then use an Immovable potion to ensure your Dark Conversion isn't interrupted and it'll give you a heal. Then after this switching back and popping Ward is to ensure your health stays full.
