Adorable mimic the discussion

[Kimika's Magical Space Cow]

Its' description from the wiki: "Destroys all standard relics in your inventory when first picked up and increases your damage by 5% per item sacrificed (counting itself). Caps at 11 items (55%), any items over the limit will be dropped on the ground".
However, there are few nuisances. It seems that in the rush mode mimic's damage caps at 40% (destroying 4 usual relics) and in the vanilla mode I was able to get 60% damage buff from it by sacrificing 11 items. Now, I do know that the cursed relic in question counts itself when picked up and therefore adds 5% to the resulting number, just wondering, since the wiki isn't quite accurate, whether it's possible to ramp it up to 65%. Any help, pwease?
