demon builder is based off the seven deadly sins, and spawns towers that correspond with each one. he uses warlock as a base model.

greed - 50 g - shadow fiend model - has a weak and slow attack to start, and gains a single point of attack damage and attack speed with each kill. you can upgrade it twice, for 50g each, to upgrade its health and armor, and increase the amount of bonus damage and speed it can get from kills. however, it must have a certain amount of kills to be able to upgrade.

lust - 85 g - qop model - has a mediocre attack. starts with the ability 'beguile' which disarms and damages enemies that dare attack it within a 1.5 second window. can be upgraded for 120g to upgrade its attack speed and health, and unlock the ability 'corrupt' which causes its attacks to apply a stacking debuff that causes enemies to explode upon death and apply a dot to nearby enemies based on how many stacks it had on it.

sloth - 120 g - shadow demon model - cannot attack, instead constantly casting 'ennervating touch' spraying slow moving waves that apply a stacking slow to enemies movement and attacks. can be upgraded twice for 180g and then 340g, doubling all aspects of sloth and his spell with each upgrade.

wrath - 160 g - lion model - has a mediocre attack. possesses the ability 'finger of death' which does massive damage to a single target. can be upgraded twice for 160 g each, adding 'earth spike' (same as regular dota) on the first upgrade. the second upgrade branches, and allows you to choose between a 1.5 second hex effect on earth spike or 200 aoe on finger of death. either way, pride gains yet another ability 'hellfire shield' which cloaks his target in flames, causing enemies that attack it to suffer damage over time.

envy - 220 g - terrorblade model - quick and strong attack, but very frail. should it come to 1 hp, it will instantly 'sunder' the nearest other tower and swap health percentages with it. can be upgraded for 100 g to grant the ability 'conjure image' which allows envy to create an illusion of itself, and again for 450 gold, increasing its attack range and attack damage considerably, and unlocking the ability 'reflection' which creates copies of all friendly towers for a brief period.

glutton - 160 g - clinkz model - squishy tower with a quick attack that does little damage. possesses the ability 'death pact' which allows it to steal max hp from the units it kills, permanently increasing its health with each kill. when it dies, it loses some stacks, and explodes in a fiery blast that does damage equal to 12% of its max hp. has three upgrade paths, the first of which costs 200 g and simply increases the effectiveness of death pact. the second is 350 g that removes death pact and replaces it with 'split shot' (same as the one that humanbuilder's gyrocopter used to have), while granting a new ability 'infernal agility' which grants 100% evasion and attack speed for 3 seconds. the third is 500 g, and grants two new abilities 'devourer', which adds some of glutton's missing hp as bonus damage, which he has 100% lifesteal on, and 'dark arrow' which ressurects enemies he kills under his control for a brief time.

pride - 300 g - doom model - massively tanky with a slow attack. possesses the abilities 'infernal blade' which causes its attacks to deal max hp damage in a cone behind the target, and 'devil's touch', which allows pride to net bonus gold from kills, which increases with each kill. should pride die, all the bonus gold from devil's touch is lost. may be upgraded for 320 g to gain the ability 'satanic aura' which heals nearby allies for a portion of their remaining health whenever an enemy dies and adds a dot to 'infernal blade', and then again for 600 g to double its health and attack damage, and triples the base bonus gold from 'devil's touch'.
