Hey there, I just reached level 40 and would like to have your advice on what to upgrade since I do not know how common the high end items are. I am guessing I should only upgrade +7..+10 stuff? And also only those of the highest rarity of its class (3* Bracelet, 4* Ring etc)? Should I always sacrifice 10 items at once or is it OK to use just a few items? Is there ever a need to upgrade stuff of lower rarity but with a high +value?

Are these items good enough to upgrade or should I wait until I get stuff with +7 or higher?
- 3* Bracelet +4
- 4* Ring +3

Thanks!

First you should always upgrade mid-tier (silver) equipment which is mostly warriors ring, earring and above (gold) and always use low tier and bronze ones as fodder. Yeah always (try to) sacrifice 10 equipments at once since its cheaper in the end. Dont bother with bracelets and amulets like i said, just go level warriors ring and earring if possible.

OK, but a bronze +9 ring has 400 attack while a silver +10 earring has 200 attack. Why should I upgrade the earring except of course if everyone already has a fully upgraded ring?

Edit: Ah never mind. I am guessing that at some point I will be replacing the bronze rings with silver ones anyway, so upgrading them is a waste.

At first, you'll just put all mid-grade equipment as a priority over all low-grade equipment. Doesn't matter much which ones you use, because you probably have other things you need to use your gold on. Then when you build up a big enough supply of mid-grade equips you can start prioritizing within them.

The items, in order of power addition, are: ring, bracelet, earrings, necklace. The gaps between each type are big, so it's seldom appropriate to deviate unless you want to bulk up all attack or all defense for some reason.

Personally, the only worn equips I ever upgrade are +10s. Eventually all of the ones you use will be +10 so you don't want to waste gold and XP in lesser equips for what is really a marginal gain early on. I do 'bank' XP in lower equips to save space by upgrading them once with one equip of the same type to get them to lvl 8-11. This also lets me upgrade a new +10 to lvl 30 in one shot and at a much lower total gold cost than half-stepping it with lvl 1 equips. Gold will become less scarce as you play, but the equipment inventory space is still a huge reason to keep on doing this.

Always look for the most efficient way to level equipment. Doing so will save a lot of time, equipment and coins. I have created an image showing the most efficient way to max a silver equipment [ring]. PM me on the discord if you want more help, im almost always on there, rarely here.

I only upgrade High Tier equipment of Rarity 9+
Its expensive and takes a long time to do, so anything less than lvl 9 item is not worth the trouble.
Also I used to have all my girls equipped but with the way the game is set up, and the items are not "taken out" of your communal inventory, I had to unequip all non-active knights.

Normally in any game that has inventory you have "active" and "Passive" - passive is the one where you carry stuff, active is the one where you equip stuff. When equipping item, it gets moved from INVENTORY into EQUIPMENT (any RPG, Crafting and Survival game out there). This game is an exception (a stupid one at that) that ANY equipped item is still counted as part of the inventory, thus it still counts towards the maximum number of items you can have.
With that being said - equip only your active girls, otherwise you will soon run out of space, and with no space you cant roll for new - maybe better Rarity - equipment.
