I've been playing the The Witcher Pen & Paper by R. Talsorian Games with a group of friends and we've noticed that if we're reading Igni and the "fire" effect (page 161) correctly, it seems absurdly powerful. As an example, here is how much damage we calculate that Igni would do to a Katakan, which has a threat level of "Hard" and "Difficult" (page 308).
A Katakan has six body locations, and fire deals 5 damage to every body location per turn.
- Head: 5 * 3 * 2 = 30 dmg
- Body: 5 * 2 = 10 dmg
- Limbs: 4 * 5 * 0,5 * 2 = 20 dmg
In total: 60 dmg
Adding in an average damage from the Igni our Witcher deals, this comes out to 60 + 30 = 90 dmg, which would instantly kill a Katakan as their HP is 80 and they have no armour. Of course, this depends on the fire effect actually being applied, but given that Igni has a 50% chance of setting an enemy on fire (page 114), even if the first Igni doesn't set the enemy on fire, chances are that a second attack would.
To clarify how these numbers were calculated: The 5 is the base fire damage being on fire deals per turn. The 3 in head is the multiplier for dealing damage to the head. The 2 multiplier in all of them is there because Katakans are vulnerable to fire damage and as such take double damage from it. The 0,5 is the multiplier for dealing damage to limbs. And, the 4 multiplier is because a Katakan has four limbs.
While I understand that Katakans are supposed to be vulnerable to fire damage in particular, it feels unreasonable that a new Witcher (we've only played four times so far and the characters have only accumulated something like 14 Improvement Points) realistically can one-shot an enemy which is supposed to be one of the more difficult ones in the game. We looked through the erratas and couldn't find anything about balancing this aspect.
Are we understanding Igni and the fire effect correctly, or are we missing something?
