Without the tekko+1 would the downgrade be ganesha's mask and the relic +2 hands? or Thaumas head and different hands
Ganesha/Relic +2 hands is correct if your attack isnt already capped.
If attack is already capped (Like NNI mobs for example), Ganesha's + Mustela Gloves.
Pretty much if your attack is already capped against the mob, use a combination of gloves/head that still gives enough haste to cap and then gain double attack/critical hite rate.
If Mustela set gets partial set bonuses, which im not sure if it does, when attack is capped, Mustela head/ Hands would be a great choice because you gain STR, DEX, Enough haste to cap haste, +2% Double attack, and increased crit hit rate. Like i said though, this depends on if mustela set gives partial set bonuses which im not sure.
Because i havnt got around to getting better hands i currenty use Ganesha's Mask/Thamus bod/Tanta +2 Hands/Tanta +2 Feet/Tantra +2 legs.
