just to get confirmation, as I never bothered with the boxes until now... but right now it has some appeal, and I have 5KTP that sits idle...
If you use a box at lvl 7 with a Excellent I elixir and the Guild Ship Shrine running it takes you up to almost 20, right ? or did they cap the thing and you are stuck at 15...
The new Otto's give 2m XP flat, no min level, so you can use from 1st level.
They are boosted by Experience elixir (up to 50%), VIP (10%), Guild ship (5%) and Mantle (5%).
So you can get up to 3.4M XP from an Otto's.

Edit - checked tables] it will get a first lifer from 1 to 20, and a 2nd lifer from 1 to 20 and a 3rd lifer to lvl 18, rank 4 with 400k XP to reach 20.
Try to get a sovereign mate - the boost is worth it.
