Perk help

I've bought a couple of perks but can't seem to put them to anything, what am I doing wrong??

 

Hi there!

Perks can only be used with rare items or better. Are your items common or uncommon?

That could be where I'm going wrong. I find it daft that I'm able to buy the perks yet I'm not able to buy any rare items because my level isn't high enough to save enough gold for them.
Thanks for your reply Bennunator

 

You can save the perks, you'll get some rare items in no time if you keep at it. You can also sell perks to get gold if you wish.

Happy Battling!

Couple questions. If I apply a perk can I remove it. Would rather get an answer here than try and find out that I can't.
Also I apparently bought 2 of the exact same perk from the store is it unnecessary for me to have duplicate perks?
Lastly, all I've seen is uncommon perks, is there anything better and how to get?

 

Yo.

1. Yes. you can remove the perk. at 500 gold for epic perks its 10 Pearls.
2. Nope. You can have many perks inserted on the same item to increase attrubutes.
3. Rare perks & Epic perks. you can buy that on the market. rare perks its around 750K Gold. Epic Perks is 1500K above Gold.

 

^ up there is way better than what I said

yep, uncommon will cost 500 gold to "salvage" then you can place it elsewhere.
multiple of the same can be a benefit either in the same item or item family, say you have a regular cannon and blast cannon and both perks are +2.5% damage then it's a win. you can and will use each perk.

rare perks will pop up in the shop, I'm not sure if they are found in crates like weapons

 

Thanks guys
