Trinket
+40 Intellect
Use: Each spell cast within 20 seconds will grant a stacking bonus of 21 mana regen per 5 sec. Expires after 20 seconds. Abilities with no mana cost will not trigger this trinket.
Actually, I’ve been equipping this trinket if only for the 40 int on it since 2.1 without ever giving deeper thought into the actual numbers this trinket equates to. It’s all fine for now since I don’t really have any good trinkets to equip. But for future reference I’ve decided to run some calculations on this trinket so I can replace it with certainty in the future. Do consider I will be writing this from the perspective of a Resto shaman so if you’re another class/spec you’ll have to modify the numbers to suit your own analysis
The first thing to notice about this trinket is that its on use function is rather deceptive in that mana regeneration is not really ticked every 5 seconds but every 2 seconds. Therefore, every spell is actually giving you a stacking 8.4 mp every 2 seconds after you cast a spell.
The first thing to check about this trinket is it’s usefulness by spamming spells for the sake of stacking the buff compared to simply not casting and getting spirit regen. As a resto shaman, the only spell that I can spam meaningfully in a 400ms environment is rank 1 Healing Wave, not only does it heal for a nice 300 per cast, you keep up healing wave and may proc Ancestral Healing as well. That costs 23 mana per cast (with Tidal Focus). Assuming you have zero lag and can cast one every 1.5 sec (due to GCD), you get 13 such casts, costing you 299 mana. Now someone at Wowhead has generously given us the detailed listing of what happens when you chain 1.5 casts here and you will see that after the trinket fades you would have gained a total of 588 Mana. Which means that the net mana gained is 289.
My shaman with 0 spirit bonus has 100 mp/5s mana regen, and not casting for 20 seconds would actually net me 400 additional mana, which is much more than spamming for this trinket. Now, if you had the SSC Relic, and it worked before talent reductions (ie (25-24)*0.9 = 0.9 , or 1mp) for you to be able to spam it on the trinket would make the total mana spent 13, and net mana gained 575, which would make it marginally better than sitting out and waiting for spirit to tick. (And if you have Insightful Earthstorm, Spellsurge, and Fathom Brooch, it might actually be quite beneficial to pop the trinket and spam). 575 mana every 2 minutes is 24mp/5s and 175 (net gain over spirit) is 7mp/5s.
Now, I’ve never killed anything in SSC and therefore I do not have the luxury of testing that out, and since spamming for the lone reason of stacking the buff is not reasonable, the best use of this trinket is to anticipate when you will be chain casting spells and pop it in advance to get the most mana out of it. For a resto shaman there is no better time than the time to repop your totems; conveniently the cooldown of this trinket is also 2 minutes, same as all of our buff totems. Assuming we place 4 totems in the first 8 seconds (accounting for lag), and we cast 2 heals which were actually needed in the remaining 12 seconds. The mana gained would be around 330, these spells would have to be casted anyways, therefore there is no opportunity cost, and we have a net gain of 330. Every two minutes this would be 13mp/5s.
40 int is 600 mana, which is 144 mana returned from Mana Tide and 12 Healing Done
Therefore, in terms of mp/5s, the trinket is as follows:
3 Minute fight : 29.8mp/5
5 Minute fight : 23.4mp/5
7 Minute fight : 22.3mp/5
11 Minute Fight : 19.2mp/5
The 13 mp/5 from the on use generally stays the same while the worth of 40 int falls as the fight gets longer. I’d say it is a pretty solid mana regeneration trinket, if you can find a way to utilize it.
On a side note, I’m seeing a drastic change of Shaman healing techniques as we progress past Gruul and Karazhan, and therefore I am planning an overhaul to the shaman notes, but not until I get experience in both SSC and TK.
