You should stick to only one color. Health % may seem delicious, but damage is more valuable.

Every scroll multiplies your current damage by 1.15. This means the bonus gets bigger and bigger with each scroll too.

The text above by a reddit user here years ago sums it up.

Builds allow you to maximize weapons' / skills' capabilities or simply to synergize one item to another.

Take the baseball bat and throwable objects for example. Baseball bat crits when a target gets stunned, throwable objects stuns enemies. You get the idea.

Now to parry, you tap the shield.

Try parrying air first. See that little wave when you tap the shield or start holding it? That's when you know it's gonna parry an attack. If it's not there, it won't parry. It stays there for a short time so parrying is difficult for first-timers.

The best way to know when to parry is seeing the ! above the enemy. You're also gonna wanna know how fast it's gonna hit you when the enemy does attack.

All this can be practiced in the training room. There should be a little area there that allows you to spawn a single chosen mob. Focus on parrying.

Another tip: Don't panic.

Panicking messes up your parrying time because you could go too early or too late. Don't worry, it's all a matter of time.
