My built is seemingly broken after removing gear and skills

I run a cold converted lightning spear build which uses call of the brotherhood and people suggested to take it off so I did and put on a different ring and changed some skills around but that build wasn’t gonna work. So I switched back to everything I had before exactly as I had it but the build isn’t the same anymore and I don’t have these massive chain kills that clear the entire screen. It seems like something vital is missing but I triple checked my gear, skills and passives and it all matches up to the guide I followed which is exactly how I had it before I tried switching to something else.

Also just last night I tried unequipping my gear to put it back on to see if thered be some refresh thing and I noticed my skill sheet damage was less than it was just before I took my gear off when I put it back on. Went from 86k damage to 83. I tried doing it again to see if it’s fix it but I lost more damage.

Has anybody experienced anything like this? You have a build that works very well but you switched some things around and didn’t like it so you put it all back but things just seemed off?

Is this some known bug or glitch and if it is how can I fix it?

It sounds like you have either a buff skill (likely) or a piece of gear that was disabled due to spirit or attribute requirements, respectively, when you took off your equipment.

If it's a spirit gem, you need to re-enable it (right-click it in the Skills pane).

If it's a piece of gear displaying as red and disabled due to not currently meeting the attribute requirements, this can be due to the gear piece providing an attribute that you need to equip it. You may need to use another piece of equipment temporarily to raise your attribute to the required level to equip that piece of gear (amulets can work well for this).
