Would you accept this trade?

Story so far...

I really want an everlasting phantasmal tonic that turns you into the rift warden thing and I have 13 zaishen keys, it is currently july so the tonic doesnt drop till next year so I was wondering if anyone could give me an answer to a hypothetical situation...

If I were to get an everlasting norn tonic, how easy would it be for me to trade it for an everlasting phantasmal tonic, like, how much of a "good/fair" trade is that because I dont know either one's value and I really can't wait next year unless it's decided that there's no way anyone would trade their phantasmal tonic for a norn one.

Thanks in advance

Boreal is 250-350k while phantasmal is 350-400k so no it's not a fair trade
Btw there's a sticky In the price check section for items like this

Firstly, the chance of getting an everlasting tonic is extremely small and if you were able to get one within 13 then you'd be very lucky.

Your best bet is to make your money through something like UWSC and straight out purchase the tonic, otherwise you're going to be most likely wasting lots and lots of money on Zaishen Keys.

You might find it hard to get a straight trade. Your best bet is to sell the Norn tonic on guru, then use the cash to get you a Phantasmal, you will probably have to add a little extra to what you earned from the Norn tonic sell, but it shouldn't be too bad.

Sell your 13 zkeys and start farming.

agree with all the above posts but in my opinion if you have a monk and can learn to 600/smite say Cathedral Of Flames, Shards of Orr, and maybe Kathandrax you can make alot of money very quickly CoF 2k a person Shards 10k a person and Kath 14-15k a person much faster than UWSC
