I'm getting this as the top Exen set, pre-Thurandaut augment discovery, excluding Hexed gear:
ItemSet 294616
Sidegrades and alternatives pending attack ratio cap or starvation:
+ Thaumas Hat*
+ Ghillie Earring
+ Altdorf/Wilhelm Earring set (Brutal/Auster saving an inv slot was my deciding factor)
+ Thaumas Coat, Tessera Saio
+ Skadi's Bazubands +1, Thaumas Gloves*
+ Epona's Ring over a Stormsoul to save inventory
+ Prosilio Belt
* Thaumas Hat and Gloves only fall behind the Chocalitzli Mask and Thurandaut Gloves duo by 2 AGI and 4 STR.
Are the new Thurandaut gloves and pants worth using for exenterator? Sorry I'm not good with ffxi math and not sure if these having more AGI would beat options with more attack(skadi hand,thaumas leg).
Thurandaut Gloves don't significantly beat Thaumas Gloves until you diminish the Thaumas set bonus with other swaps, and then only marginally so. After swapping Thaumas Coat for Thurandaut Tabard, one would need to replace both the Thaumas Hat and Thaumas Gloves with Chocalitzli Mask and Thurandaut Gloves to see any appreciable gain (2 AGI and 4 STR). Separately, Chocalitzli mask and Thurandaut Gloves are just about equal to a Thaumas Hat or Gloves getting +5 STR and AGI from set bonus.
Thurandaut Tights provide more raw power to Exen, but fail to catch up to Thaumas Kecks' 20~ Attack and possible (if unlikely) fSTR gain from the listed 9 STR plus 2-5 from set bonus. I'd say keep the Thaumas Kecks going, unless Thurandaut gains good augments from Coalition. So far though, Coalition augments appaer to be mainly HP/MP, so don't hold your breath.
