9! I've decided to countdown the final achievements in Isaac as I get them. Beat Greedier today with Tainted Samson. Broke the 3 run streak, got this one first try. Found some interesting synergies and anti-synergies specific to this character. For those not in the know, this character builds rage as he does damage, leading to a Berserk activation after enough is dealt. The Beserk mode has a short range, high damage bone club that lasts as long as you keep killing enemies. Since Greedier is constant waves of enemies, it's real easy to steamroll a lot of it once Berserk procs. However, I found the first anti-synergy early in the run with Ipecac. This adds explosive tears. Very powerful, but lots of self-damage potential. Combined with the Berserk I found myself coming out of it right as I hit fire, causing the Ipecac to shoot instead of the club swinging. TONS of self damage happening. A floor or two later I found another synergy specific to Ipecac and Berserk: Brimstone, which is a charged laser blast. Adds the explosive effect to the beam, but the need to charge stopped the point blank explosions. Managed to get lots of health, tears and damage thanks to getting the Swallowed Penny, which drops coins as you take damage. Late in the run I found another anti-synergy that's going to seem like a typo: I had too much damage. The problem here was that the damage would proc Berserk VERY fast, cutting the Brimstone beam short and leaving large gaps where there was no damage happening as I rushed in for the Berserk attack. I did manage to still win pretty easily, but the build would have been much stronger in the end without the characters built in ability.
