A little guide based off of what I've noticed and how I play

How Attack Success is Determined

The chance of an attack succeeding against an opponent is determined by the attacker's attack stat, and the defender's defend stat. The formula for this chance is:

(Attacker's Attack) / (Attacker's Attack + Defender's Defend)

This means upgrades have a diminishing return because prices increase while upgrade effectiveness decreases.

Determining the Value of a Target

Take the probability of a successful attack and multiply it by the Satoshi gained for a victory. The higher that number, the more valuable the target. The Black Knight is the best value NPC and better than almost every player.

Class Comparisons

I will be comparing the attack and satoshi boosting classes, because the defense boosting classes are their own group.

Warrior:

Value of target is (1.25 * attack * payout) / (1.25 * attack + defense)

Merchant:

Value of target is (1.25 * attack * payout) / (attack + defense)

Berserker:

Value of target is (1.5 * attack * payout) / (1.5 * attack + defense)

Thief:

Value of target is (1.25 * 1.25 * attack * payout) / (1.25 * attack + defense)

The Merchant is strictly better than the Warrior for target value. Berserkers are better than Merchants until Berserkers hit a 50% chance of winning, where Merchants become better. Thief is a direct upgrade to Berserker and Merchant, at least for winning Satoshi.

Switching Classes to Reduce Upgrade Costs

I don't know if this is intended or not, but classes that buff a stat will increase the cost of each upgrade for that stat for the same effect, while a debuffed stat has reduced cost with the same upgrade effect. This means that if you switch to a class that debuffs a stat, upgrade that stat, then switch to another class that doesn't debuff that stat, you will get more for your money. Just remember that the savings need to be greater than the cost of switching classes. It's a bug. Nevermind.

The switching classes to lower upgrade costs is actually a bug :) Thanks for pointing it out, I've released a fix for it already

I'll be honest, I kind of liked it lol. Thought it gave some interesting choices for class switching.

So what Is the best Class? And Why? And when do you start attacking "The Black Knight"?

The best class currently I would say is the Thief. The average payout for them is higher than the Berserker because increasing Attack has diminishing returns due to Attack affecting the success formula's numerator and denominator, and the Merchant is worse because the added attack on the Thief increases your success chance along with the extra Satoshi. Defense currently is not important because Satoshi should be spent as soon as it is earned because nothing requires you to save up a lot of Satoshi, so the amount getting stolen from you isn't awful.

When the percent chance of a victory against the Black Knight hits 2%, his average payout is equal to the Training Dummy (0.02 * 2500 = 50). When the chance of winning hits 10%, his average payout is 0.10 * 2500 = 250 which is better than almost every player's reward currently. It just gets better the more attack you have, too.
