Sadly, your upgrading has nothing to do with the refine event since you were not capitalizing on its pro, rather sinking into the trap that WP made for you.
A) Enriched hammer --> THIS is the one to make your important and less abundant equipment +10 on a much cheaper cost.
Mad bunny event--> This event has nothing to do with your important gears from +1 to +10. This is for upgrading from +10 onwards, as well as YOLO-ing equipments which have high value at +9-10 onwards but are not expensive or hard to find when not upgraded. Examples: mad bunny special, crimson weapons etc.
The thing to note with B is that WP understands that if you did not plan ahead, you will be unable to capitalise on the +10 upgrading madness, so in this season there's always a tons of safe certs (and now blacksmith blessings) in the cash shop boxes so that you can upgrade your gears to +10. BUT honestly, this is still expensive upgrading since the event has nothing to do with normal upgrading from +1-+10- especially if you spend zenny buying the certs and blessings from others.
Next time prepare ahead and do all your +10 upgrading during Enriched hammer man. Sadly, it means if you want mad bunny now, you will have to spend the cash and face the RNG OR buy from others. Failing 10-20 times is really nothing out of the common on the 9% rate. If you can't deal with potentially gambling 2B+ for that upgrade, don't do it honestly.
