my question is how can i edit this that if failed the item/equipment will never be lost or destroyed.  and how to change it success chance rate.

Thanks

[sader1992]

failedrefitem .@part;

to

//failedrefitem .@part;

for to not delete the item

doing that would mean there is nothing will happen when fail so you may want to add fail effect instead this line

------------------------------------------------------------------------------------------------

for the success rate >> this script use `getequippercentrefinery` so you can edit it in `db/(pre-)re/refine_db.yml`

or you can just remove this and add your success formula

if (getequippercentrefinery(.@part) > rand(100) || getequippercentrefinery(.@part) > rand(100)) {
