Don’t worry I’ll be making my video soon with my peltasta eating all exp card from lvl 1 to lvl 10. coz we c3 peltasta doesn’t need to touch a single cards to level up lol.
I’m planning on doing that after all quest are finished probably that would be lvl 240.

I’m just waiting on the addon that uses the cards for me. It’s gonna happen.
Not as much as 1000, but I did use all 283 pieces of Lv11 cards (currently the max you can get with monster kill achievements and exploration)[you can get more via TBL, but I don’t do that].
i’m 266 as well and considering just card to 280 as well, what’s a maven, is it something you eat? lol
