With DM 12,5%, Gem 13%.
Your weapon has base ~500 matk (staff) or ~400 (rod).
You can still do much more enhancements with Golden Anvil.
Yes, in the case where you have only 1 last potential you should NOT briquet your weapon.
The point of briquetting is not this. Briquetting should be done BEFORE you start upgrading your weapon (or spending any silver on it at all), if you get a nice briquet, (10%+), open sockets, awaken it and enhance it as much as youād like after that, using Golden Anvils if possible.
The thing is it looks like you donāt understand what you are talking about, you are considering making a Transcendence 10 weapon, do you understand how much time it takes? If you spend DAILY 1,2m on 2 rerolls for each of the 2 cubes you need around 1 year and a half to get to transcend 10.
+10% on base weapon matk is 40~50+ matk you assure on your weapons, if you get to T10 (550%, 1 and a half year), they turn into 220~275 matk. +1 Anvil enhancement gives 18~20 matk which turns into 99~110 matk.
Letās say you use that final 1 potential youād get and get 2 success and a fail (be the fail before or after the first success), youād be off with +18 matk, +20 on a 290 weapon. You would actualy need to have 3 successes in a row with your final potential for it to be worth more than those +10~13%. Each try costs ~2mill after from +12 on. The thing here is, if you are commited to upgrading a weapon to high levels of Transcendence, to a point where you will farm enough of it to make a 10%+ briquett (which you should since that already takes lots of time by itself), upgrading only finely briquetted weapons will end up giving you better results than no briquetted ones.
Obviously, this is all min maxing, people into this arenāt even spending Blessing Shards because everyone have already seen how powerful level 290 gear is. 1 and a half year is no joke, you are not losing much by wasting 15~30 days going for some finely briquetted weapons. Level 330+ weapons are probably something that we canāt even imagine. Just think about how the best INT staff is giving 22 INT and many rods/maces/staffs can give 100+ INT on R8. Also a very big matk gap.
The further the game progresses and the better the new weapons are, the more Briquetting will become important.
OP: If you are making an Alchemist, go Tincturing 15, you will make more money and make yourself cheap potions.
If you have hardcore friends saving their shards for Rank 8, you might want to consider what briquetting can do but it takes a LOT of effort from the farmer and most likely wonāt give you much profit.
