Synergy / Sin Energy

Synergy unlocks after reaching stage 415 and beating the first Learn To Walk Again challenge.

## Explanation

Synergy is fairly complex and the terminology can get confusing. Here's an attempt to explain it one term at a time.

**Synergy Progress:** When Baby Demons are assigned to a synergy, the center bar begins to fill. The rate at which the center bar fills is 1 per BD assigned per tick. Synergy Progress bonuses increase that rate. The later synergies require more progress to fill the bar than earlier ones.

**Synergy Experience:** Each time the center bar fills, that synergy gains 1 point of experience (the box on the left.) Synergy Experience bonuses increase that number. Each time the experience bar fills that synergy gains a level. Each level reduces the progress required to fill the center bar by 10, to a minimum of 10% of the base, but increases the exp(bar fills) required for the next level by 10% of base.

**Synergy Power:** Each time the center bar fills, the box on the right gains a number of points equal to the level of that synergy, multiplied by your Synergy Power bonuses. The previous synergy loses a number of points equal to the level multiplied by 2 (but *not* increased by synergy power.) Therefore, you can think of synergy level as increasing the rate of conversion, while synergy power increases the efficiency.

**Synergy Points:** Each synergy gives a permanent bonus depending on how many points it currently has, as shown in the boxes on the right. These bonuses have diminishing returns after 1000 points. The later synergies give lower bonuses per point than the early ones. Each synergy after the first, unlocks when the previous synergy reaches 1000 points.

**Sin/Cos/Tan Energy:** (shown at the top of each page) is also generated each time a synergy bar fills. The amount gained per fill is 1/3/6/10/15/21/28, depending on the row leveled. It can be used to both purchase dump bump tokens, and is the main resource for Synergy V2. It is likely recommended to save for Synergy V2 instead of spending it on dump bump.

## Strategy

Synergy is very powerful and in general you want most of your BD's in it after unlocking it. Because of the complex way progress, level, and power interact it's practically impossible to optimize BD allocation without using a tool such as Alex's spreadsheet to assist you.

Unlocking pages 1, 2, and 3 is fairly straight forward (just do each LTWA challenge after soft capping the previous page) but once page 3 is unlocked you shouldn't soft cap it immediately. While slime and alchemy bonuses are nice to have, they have the lowest soft caps and the highest progress requirements so getting there would take a very long time at that point.

It's better to soft cap class exp (you'll want it to level Machinist and Conjurer, which become your main classes at this point) and then go back to page 2, because at stage 475 the generator starts boosting synergy exp. This begins a feedback loop where generator bonuses (from synergy, Machinist, and gen V2) increase the rate at which synergy levels, which means more essence and generator bonuses, and so on.
