Uhm ive got a question what that t5 mean?

 

thunder powder tier 5

 

I think this build is a bit easier to attain (and I've done so) https://wynnbuilder.github.io/#4_0Sz0S-07z0IZ0Zi0Dw0730TY00J0P0g140C0E0m000010000B
any thoughts?

 

i mean it works you just lose mana regen
you dont need super optimal build for leveling
