3 main blocks i used were Sticky Block(S), Piercing Block(P) and Booster Block(B). start by placing a sticky in the first column and booster and a piercing at the last after that make a bumpy road with stickies and put boosters on top of piercing. the end result should look like this: S / - / S / - / S / - / S / BPBBB. After that you can put another big coulmn at the beginning. Put a Digestion block on top of one of the piercing blocks if you need to dps down a boss fast.
