Fair note, All skills and passives will have been reset prior to U29, so reallocating them will be your first priority. Especially if your using light armor passives.
If you see me anywhere. Know that I am sitting back with a bag of popcorn, watching as ESO burns the goodwill of its player base with practices that only disrespects the players time like it did to me and many others...
If a game does not respect your time, best thing to do is move on from it and find something else.
Most trash has about 9.1k resist and bosses have about 18.2k resist. So you want a target pen that factors in the content you do, if you run group or solo and the buffs you can expect (Major Breach, Minor Breach etc).
Spell Pen:
Light armor passives can boost pen - especially if you run 7 light armor pieces.
Max Piercing in the Warfare CP constellation.
Then pick and choose from among the following to reach your target:
Access to Major Breach (like Elemental Drain).
Access to Minor Breach. https://en.uesp.net/wiki/Online:Buffs#Debuffs
Sharpened gold weapon(s).
Spinner' Garments set x5. (I'm not necessarily recommending Spinner's since there are so many good sets out there for mages but it is a solid source of spell pen - https://en.uesp.net/wiki/Online:Spinner's_Garments)
