On Pyn’s first eTR, the larger problem was finding and using all the lower level equipment. Not the bows: I had several good ones, especially the free Unwavering Ardency (from the 10th Anniversary Party) that’s more than powerful enough until you can wield a Pinion. I simply wanted useful goggles, boots, trinkets and the like.
Cannith Crafting to the rescue. Update 32’s revised features really helped customize new tools that supported normal and Insightful bonuses for any items. Most importantly, anything I made with bound shards is bound-to-account, making storage of the items easier by transferring them to my bank characters as I TR.
By finally getting my crafting level up to level 29 or so right now, Pyn’s equipped with Tendon Slice and Armor Piercing bonuses, Insightful Dodge and ability scores. Fortification was the only thing I couldn’t swing in, so I had to use some older Heroic items to keep it (and Deathblock) in place until I reached level 25 or so. On return to level 28 (where the bulk of my best gear is usable at minimum level), the central crafted items may be the goggles (WIS/Insightful WIS for maximum Ranged Power and AC), boots (Dodge/Insightful Dodge), gloves (DEX/Insightful DEX, Tendon Slice) and perhaps bracers as a wild card (Resistance). The necklace slot is also up for grabs as the Epic Golden Guile is less useful now, but I have no idea what to add. Same is true for perhaps one ring.
As to what Epic Past Life feats I choose? Doubleshot and Fortification. I wanted a quick 2nd Doubleshot feat after epic life #2 but I was impatient in rebuilding that karma back in the Primal tree. I’ll grab that second Doubleshot stack (3% per stack, maximum 3 stacks) on another eTR.
Changes with Updates 33 and Improved Deception did affect the Zen Archer build with mostly positives than negative. For one, more Dodge and stacking maximum Dodge with the Monk stance adjustments, so Pyn has around 38% Dodge (with items) in Water stance. But what the stances gave, it also took away by moving the critical threat multiplier from Earth stance to Fire stance. As Fire stance is rather WIS-lowering and gives no benefits while in ranged attack, the Zen Archer would only go to Earth stance for a little more PRR now. Wind stance remains only useful for a DEX boost and gives no other benefit for a ranged (as opposed to thrown) weapon user.
The bluff spinning effect that Improved Deception created was defined as a bug with Update 34, so that’s gone. More challenging is the aggro change in shooting one enemy in or near a group of others, which aggros the entire group. For me, I’ve adjusted my gameplay to use height and barriers that restrict a mob’s ability to bum-rush my party. I still use two or three hirelings (thanks for the extra kitty, SSG) in solo play to grab the aggro first when practical.
When there’s nothing to slow down a zerg attack, I ramp up my own. The Zen Archer still has potent damage per target with all of its Ranged Power and the ability to use Ten Thousand Stars and Manyshot to improve attack speed and Ranged Power. She may not be using Improved Precise Shot (she’s a sniper) but she takes down single enemies so rapidly that the change isn’t particularly bad. (I am considering, as you should, adding IPS as an option for faster clearing as one of my last Epic feats, since the aggro change can work against you.)
Combined with the right bow, mobs of 10 or more are killed rapidly. Add in a few uses of Shiradi talents such as Otto’s Whistler and Pin and smaller groups are easily managed.
The Zen Archer’s talent to stand and defeat armies of enemy archers remains very good. With the extra Dodge in Water stance, it’s better. No other ranged/thrown weapons character I know of could stand toe-to-toe against the gnolls in Epic “Chains of Flame” without losing 3/4 of their HP or worse. With all her defenses up, Pyn might lose 1/8 of her HP.
So, I’m considered the new Racial Reincarnation options. As an Elf, Pyn could work to get that extra +1 DEX and Action Point. But frankly, I see this new option as a bit underwhelming, especially since the price of using Racial Reincarnation works like a Heroic True Reincarnation (favor, flags, quest completions reset, empty your TR cache). That’s a lot of sacrifice for a little gain. And Racial Reincarnation is mutually exclusive to other reincarnations. You can’t make both a Racial and Heroic/Epic TR at the same time.
