Should I burn Chevalier NP5?

She's the best tank now and not some kind of DPS saber, her only rival is Georgios and Mashu.

Maybe she can be a bit of help when breakbars thing coming soon.

I was using Chevalier heavily to tank for my Raikou for a good couple of months until I started getting flooded with 5*. As the others have mentioned an amazing tank to keep squishy damage dealers alive aka Berserkers. At Np5 you can stack some nice debuffs, more so for an arts stall team.

The item is still available for over a year. So in that time you'd probably have farmed sufficient Rare Prisms, and possibly less regret burning your NP5.
Then again, you would have argued with yourself in your head endlessly. Like asking yourself, how hard was it to achieve an NP5 SR. Would you be willing to max another one if you get/need it? How much have you spent on leveling it? etc.
The decision is made by you, and if you do it, do it without regret/s. I'm still hurting from the time I burnt my 2nd Jalter because I didn't know about NP2 and onwards.

d eon's only 3rd skill is useful if you dont need this skill there is no big problem. besides d eon's np is just a trash you dont even need to use it
