Perks for weapons but hitpoints not showing

I added a perk to my sniper canon and rare blast canon. +20 hitpoints but the damage the weapon does is not updated. If the damage was 207 before , it remains even after fitting a perk.Help

 

Those hitpoints are health points for your ship

 

you need these ones to increase cannon damage

 

i got one of this but the uncommon perks.but how to use this?how to fitted into items?

 

You probably need to evolve your cannon to unlock perk slots, you can see them (little circles) when you tap on the cannon in question.

 

But it says compatible with all items? Why would it say that then?

 

and why does it fit with my sniper canon if its not compatible?

 

How do you get epic perks

I've only seen uncommon in my shop

 

•common weapons need to be tier 3 before applying perks.
•uncommon tier 2
•rare tier 1
•epic 2 perks @ tier 1
•legendary 3 perks @ tier 1

I had an epic perk in the store the other day. +150 hp. Man, I wish I had 1.3 mil gold to buy

 

Because it is compatible with all items.
Apply to any item to increase your ships hitpoints.

 

It is compatible with ANY ITEM, but you have to be in the correct tier to apply the perk

 

I have no idea what you are trying to say?

Its compatible with any item, end of story. A weapon is probably not the optimal place to put a hp perk, but it works just fine.

 

Maybe you should do some research on weapons. It clearly states on them when perks can be applied.

Common: Tier 3

Uncommon: Tier 2

Rare: Tier 1

Epic: Tier 1 x2

Legendary: Tier 1 x3

 

Hopefully this helps.
