You heard right folks. This is a great opportunity to get your beloved uniques upgraded possibly for free. Read on if you're interested.
I offer you one level of unique upgrade (possibly more if under level 25) for one ToT box + one 2013 scary skeleton key. If I use only a proportion of the boxes to get the 20% crafting booster, then I will also return you a proportion of the boxes that are remaining along with your upgraded unique. If I open all ToT boxes and don't get the crafting booster then I will return you your original unupgraded unique.
So, lets say I am able to pool together 50 boxes before I start crafting and you've contributed 5 of those boxes + 5 keys. It takes me 20 attempts to get the 20% booster - leaving 30 boxes left. I will upgrade your unique 5 levels and return you that upgraded unique + 3 boxes + 3 keys. Sounds like a very good deal if you ask me - 2 boxes + 2 keys for 5 levels of unique upgrade... Consider what that would cost you if you used only CoC 50% + the alliance booster.
If it takes me 40 attempts to get the 20% booster (leaving 10 left), I will upgrade your unique 5 levels and return you that upgraded unique + 1 box + 1 key. Still looks like a very good deal.
If I go through 50 boxes and don't get the 20% booster, then I will return you your original unupgraded unique. You lose your 5 boxes sure, but you'd have to take a risk at some stage with your 5 boxes for crafting anyway - much better it be pooled with me I think.
If there is rounding required then the people who have the highest fraction after the whole number get priority for the remaining boxes.
Of course this whole thing relies on trust. Both that I'll return you your stuff and that I'll accurately report the results of unboxing to you. So why should u trust me? First, I've upgraded and borrowed stuff from people before. They can give me good references. Second, I got tons of nice uniques in my inventory and I'm not into PvP. Most people know me as a veteran player of 1.5 years who's really rich. This is all the more reason I'm not going to keep your stuff - I'd probably never use it and my reputation is much more important. Third, this is a win-win deal. I got a lot of fuel and I need insurance to get the 20% buff for a ton of uniques I want upgraded myself. I'm willing to spend a bit of fuel to get that insurance. And I'm sure most people will think the person wanting their uniques upgraded is getting a good deal.
I'm looking to craft at the end of this war round. Find me in game if you want to trade.
