going off what matrix said about the shields, I think if it had a 20% chance of blocking a melee attack it would be good. After this, it goes up by 10% each time your hit, until a melee attack is blocked. But when you die, it resets back to 20. Also this only happens once, meaning you must die for it to activate again. Btw I got this idea from my 2nd favourite game, hollow knight 😀
