Organ gun base S5 AP 5+ long range.
Misfires 2.78% has the -1 to hit 27.78% (excluding the misfire result)
So a total of 29.56% of "problems".
Ro forging changes Misfire rate to 0.08%.
-1 result 5.4% (some of the misfires will change into this result hence its higher than 4.63%)
So a total of 5.48% of "problems".
Engineer can re-roll only a single dice.
Misfire result 0.46%
-1 Result 6.95% (Allot of the misfires are re-rolled into a -1 to hit and a few remain misfire)
So a total of 7.41% of "problems".
Now for destructive power. Strength bonuses add 1/6 wound chance but only against a certain combo of toughness foes. (T3 does not care if its 5 or 6)
But they also have a chance of decreasing enemy armour saves by 1/6th but only for armour of 4+.
Hit chances add a 1/6 per hit boost against everything always up to the point of 2+.
More hit chance does negate cover boosts. Considering this it means there are only a few situations where the Strength bonus out does the accuracy (4+ armour 4+ Toughness) We now need to consider that without forging the 29.56% of "I Swear too much" would reduce the effectiveness of the STR boost. So when pen rune is used we must always add a engineer or we might as well just do accuracy with forging for the same power but more stable performance.
=> Base organ gun 120 points 29.56% of "problems".
=> Accuracy + forging 170 points +1/6th kills 5.48% "problems".
=> Engineer 190 points +1/6th 7.41% of "problems".
- 70 of these points are spend in heroes so good for point reallocation.
- Note the engineer does provide entrench but in all honesty its only a point denial or redirector. Entrench can be ignored as other cannons won't care and most CC units do not worry about the -1 to hit.
=> Pen Engineer 230 +3/6th 7.41% of "problems".
- The most destructive combo save for one other. But its situation is limited against some enemy's (elfs, demons with ward save etc)
=> Accuracy Engineer 215 points +2/6th 7.41% of "problems". Works against everything.
=> The last upgrade is grimm. He is a 165 engineer that grants +2/6th and works amazingly well with pen rune or accuracy for a 3+ or 2+ long range shot at S6 or S5. While he does cost allot he can also provide his own weapons fire to the fray. The issue is his limited range I would love him more if it was 24-30" and 1 shot. Then again once close he does rock the joint.
Anyway from all of this we notice that pen rune has a big situational issue. The most stable set up is accuracy + forging. Engineers are best used in a accuracy only set up unless you know who you'll face.
!!!A good reason to use a engineer is to reallocate rare points to hero. If you normally bring a organ with accuracy and forging. But you see you have between 90-115 points left for Rare. You can take an engineer and use the 50 opened rare points to buy a flame cannon!!!
