Hey guys !

First of, I won't discuss the Secondary stats that purify provides here, refer to this thread if you want to read about them

https://forum-narutoen.oasgames.com/page/show-post-29333-1.html

Now purify as the system is very simple:
It adds % of the equipment refine stats as additional stats (Example: Lvl 10 refine provides 665 stats, a 100% purify on it would provide additional 665 stats)

This is a level 8 refine.

White = 0-20%

Green = 20-40%

Blue = 40-60%

Purple = 60-80%

Gold = 80-100%

Now there will always be a love/hate relationship with this system because it's very luck based (there aren't any tricks of getting a higher purify %)

You can lock the good purifies with the Protection Runes so you can't destroy them.

You can improve your % by using Breakthrough Pills also but 1 pill gives only 1% and they aren't easy to get (max is 20% on each equipment , 20 pills)

Best way to do purifies?

Now as I talked about in my Secondary Stats discussion thread you will want to prioritize Initiative / Critical / Injury stats always.

Which means if you get combo/control as first gold color purify I suggest to destroy it/not protect (Why ?? Simply because Protection Runes as more expensive than normal purify and they need to be used even more, so you should only aim to protect the stats your prioritize firstly)

The suggestion of doing purify is like this:

1. Spam as many purifies with destroying all gold in the way until you get a gold initiative stats.(I suggest having ready 500+ purify and 200+ protections at least)

2. Lock the initiative one and spam to try getting Critical/Injury ones.

3. After getting those 3 gold you can aim to get control/combo in purple/gold colors also.

Now of course this is just a suggestion and this applies the most to Pos1 equipment if you want it to be really good.

You c*ways lock other golds and then pray for getting initiative/critical/injury however this is not efficent at all because of the potential huge amounts of Protection Runes that you will have to spend (reminder: you need more of them + they cost more)
