Through reforging, you can make a Yumi with 40% SSI, then after imbuing it up, use a Forged Metal of Artifacts to enhance Ash, for 50% SSI.
Anyways, Armor needs a SERIOUS revamp too. I spent about 3 hours yesterday crafting a full suit of Human Plate Armor out of Iron for right resist setup, then enhanced to Valorite with a +60 ASH. After working on it with a spreadsheet, i discovered it would take a total of 7 imbues to max all the Resists at 70 (Not even Corpse Proof), 2 imbues on the Leggings, 1 on each other piece. Where the Gargoyle Plate Suit i made awhile back, took a grand total of 5 imbues for all 70s Resists (Corpse Proof), 2 on the Earrings, 1 on Kilt/Leggings/Arms.
The Human Platemail Suit has a grand total of 70/70/70/70/70 Resists, with 40% LMC/+15 Health/+48 Stam/+15 Mana/+12 MR
The Gargoyle Platemail Suit has a grand total of 74/85/70/85/73 Resists, with 40% LMC/+15 Health/+40 Stam/+48 Mana/+8 MR.
Something is seriously wrong here, especially considering that Leather Armor is so close to Human Plate Armor in Resists, when Plate Armor is heavy, requires high STR, is not meddable, is not stealthable, the materials for it is harder to get, it requires a higher skill level to craft, with a higher failure rate to create.
