When is it wise to fight

Since battles are auto-resolved, most fights are won by decisions made before the battle has begun — Sun TzuThe defender has a massive advantage in Callasia, often 50%+ effective health compared to your units. In some extreme situations they might have over double your effective hp. This means you shouldn’t engage a fight unless you have some sort of advantage. This is a list of the advantages that can make starting a fight a good idea. The more of them you have, the better. If you don’t have any, just don’t do it.-You have a bigger army than them. This is pretty self explanatory. More troops deal more damage, making the fight better for you. Loosely, a 30% advantage against someone fortified on unupgraded terrain or a 50% advantage vs a fortified citadel should be enough.-You have strong cards. This is also pretty obvious. One advantage the attacker has is that they know what turn the battle will happen, making cards more easily deployed with effect rather than making defense guesses. A well-timed Smite or Charge (or both) can lead to a huge advantage in the initial round of combat. This is particularly important if the opponent cannot reinforce, as they cannot replace the troops lost in the initial shock.-Your opponent is out of position. Combine map awareness with your opponents’ poor choices. A hero attempting to capture land takes a 50% penalty to unit defense, and razing incurs the same penalty. Building or movement actions are neutral in terms of unit defense modifiers, but it can be more advantageous to attack a fort before the hero on it can build a citadel.-Reinforce Points. If one player has a reinforcement point and the other does not (or has no gold), this hugely influences fights. If the opponent has a lot of gold and a reinforce point, and you do not, then you better be able to win combat in one round, because otherwise things are going to get messy. If you have a reinforce point and the opponent does not, then the longer the game goes on and the more gold players amass, the less tenable it is for them to keep holding their location. This is one of the big things that can prompt an attack. If both players are sitting on citadels, staring at each other, then at some point the advantage of denying them a reinforce point (since you are fighting on top of it) becomes greater than defender's advantage.-Your opponent’s composition is rubbish. Maybe you are fighting someone who has never read this guide and their army is 20 golems and 50 phoenixes with no other units. In which case an army of equivalent gold cost with 3 heroes, each with a front liner and spread out decoy units, will annihilate them. You can even increase the effectiveness of your decoy units by stacking up your damage dealers, since the enemy has no decoys to overkill.Concise list:Larger armyStrong cardsBetter positionBetter reinforcementsBetter unit compositionThank you for reading my guide and may you crush your opponents beneath your iron boots/hooves/skeletal toes.
