Thanks but I'm not fighting battles on the field (thus terrain is irrelevant) and I'm fully aware of the combat pentagon, but it's effectively useless when using auto-fight in the spire. When I first started fighting in the spire, I used the pentagon, but found that trying to work out the troops required was a lost cause, for auto-fighting in the Spire, not on the field - I gave up for quite a while, because the pentagon only works for those who fight manually on the field. Then I read a lot of threads and watched a lot of online videos from players and found the best strategy for 'fighting without knowing how to fight'. 90% effective and 10% negotiation is a price worth paying.
I don't play on an app and how can they be hidden on auto-fight, you click auto and win or lose.
As I mentioned, the strategy which I have found most usefu against the AI, is using one single troop x 5, or 2 troops to cover depending on the opposition. As also mentioned, it has been successful in getting to the top of the tower for months, with minimal negotiation required. Having the extra 50% for light range or heavy range, or mage has been successful no matter what the oppostion, the strategy keeps my troops above the necessary units required for second level (or third level attack). I use the same strategy for the first 8 battles of the tournament and haven't lost a battle yet.
However, the light melee 75%+ extra attack does not work, it does not give any advantage and my troops are wiped out in the first auto-battle - when they shouldn't be, even against fewer numbers of the right opposition for light melee - any of them (tried them all in successsion) then decided this particular one is like it works against my troops, not for them.
I am also using the mage multiplier and heavy ranged power-up, with the same strategy - thpse are working as expected, reducing casualties to minimal.
It was the same with the dwarven armour that I gained when I upped a level to Embassies, it didn't work - it didn't protect the troops and I wondered what the heck it was for.
I just want to know why one particular boost for attack doesn't work at it should, when all the others over the past months have been effective. This is the first time I've used this one, usually I stick with light range, heavy melee or heavy ranged 50%+ attack, but the MA decided not to gift me one this week, instead I got stuck with 75% of nothing.
