All effects listed on the card (negative conditions, elements, healing, etc.) have a positive but undefined value. Note that only the values and effects as listed on the cards and the attack's value (used for the 2x modifier) are considered when doing a comparison. This includes any listed bonuses on the cards that are in effect for the attack, such as from a performed elemental consumption. No other game effects or conditions should be considered (like poison, wound or item effects). Thus, these would be the rulings in the following cases:

2x and Attack 2 vs +2: Ambiguous (2 x 2 = 2 + 2)

2x and Attack 2 vs +1: 2x is better (2 x 2 > 2 + 1)

2x and Attack 1 + 1 from consumption vs +1: 2x is better (2 x 2 > 2 + 1)

+1 vs +2: +2 is better

+1 Stun vs +1: +1 Stun is better

+0 Stun vs +2: Ambiguous

+1 Stun vs +1 Fire: Ambiguous

+0 Muddle vs +2 Stun: Ambiguous
