now, I have various other spell damage gear etc, but this gear is the one that gives me the most effective health. my main concern is my choice of trinkets.


In my bag i have like so many trinkets but the ones I would see me subbing for certain fights are Ancient Aqir Artifact and the figurine - crimson serpent.


currently, i use the serpent for trash, and for boss fights where i feel like healers will always be on me and bosses dont necessarily hit hard or where i really need the boost in threat output. (i.e. ZA timed runs, KARA, heroics)

However, I use the moroes trinket for harder hitting bosses (gruul, mag, lynx etc)

now, i'm wondering, when does Ancient Aqir Artifact come into play? Granted its a fairly new pick up for me but, I just cant really see me finding a true condition to use this in. I see the value of it with chain chugging ironshield potions, sure. But the effect is only for 20 seconds and if u are activating the use effect, i mean, is the armor increase (in combination with chain chugging pots) really going to mitigate that much damage? for all intents and purposes pure avoidance trinkets like the moroes lucky pocket watch just seem better.

anyway, thoughts on that. oh and i have Aldori Legacy Defender. Which shield for what issues?
