3 questions for mag sorc pve

[MR.hyde]

1st) should i keep my dmg over time up during execute phase or only spam my execute? i noticed the red crystal frag does more dmg then my execute so i assume i should prioritize it but what about the bear trap (fighters guild skill for more crit dmg) or my wall of elements/orb?

other executes scale with lower enemy hp but sorc execute stays the same dmg.

2nd what jewelry enchantment in maelstrom arena? bloodthirsty, infused or arcane? i dont think the mobs have enough hp that bloodthirsty is worth it, i tend to infused. opinions?

3rd) should i go 7 light armor or 5 light 1 med 1 heavy + undanted passive for more max stats? i have only 600 cp and put all my blue cp points into dmg, i looked up alcast guide and he said i should prioritze tankiness for trials so i wonder if i can stay cp glass cannon if i have 5 1 1 setup or if i get more dps if i go tanky in blue cp tree and go 7 light armor?

1. Depends. Generally you are still going to do your full rotation but instead of your normal spamable, use your execute. The only time you wont use your full rotation and just spam execute is there is only 10 seconds left in the fight. (which experience will answer that for you) where you wont get the full damage out of your DOTs.

2. Just have to experiment and find what works best for you.

3. I believe general consensus is 7 light. the undaunted passive won't really make all that much difference. and light armor passives scale all the way to 7 now instead of 5+

1. im not a magsorc but a magcro and i keep up my static rotaion until the 21m dummy is at ~1mil hp then i only spam my strongest spells

2. just use standard jewelry dont spent to much on your gear for a stupid solo arena. i recylced my false god(divine), put health glyphs on each piece, iceheart as monster set and mothers sorrow for jewelry + stave (also the same jewelry im using on my real build)
with that setup i do in 3/4 runs a flawless run

3. 7 light or 5-1-1 depends kinda on class, on my magcro im already over the required penetration (permanent at 18200 and hitting sometimes 23000) and the 2% extra crit chance dont increase my dps more than the 4% more magicka. thats why i run 5-1-1

but either armor set it wont do THAT much damage difference.
