Some game mechanics questions

[Blinking Mirror]

When using Unite Attacks, is the multiplier for the weapon rune incorporated in the damage equation? I ask because a fire/lightning rune attached on a weapon does damage after the attack as a seemingly separate event.

How are critical attacks and/or multiple attacks determined? (What stats are needed for either?)

How often does the Blinking Rune (or casters with E affinity) backfire?

Thanks.

Yeah, as you noticed weapon runes that do damage after the "main" damage such as the Fire and Lightning runes don't affect unite attacks. However, runes that add to the main damage, such as friendship, exertion, and kindness runes do affect unite attack damage.

How are critical attacks and/or multiple attacks determined? (What stats are needed for either?)

Criticals depend on TECH and LUCK, while multiple attacks depend on SPD.

How often does the Blinking Rune (or casters with E affinity) backfire?

Not sure.

Thanks for the response.

Another question: Is the greatest amount a stone (stone of defense, etc.) can give 3?

Yes
