What this update means for your run

Demo 0.5.2 changes Chemist from doubling its Poison bonus at level 3 to adding +1 on any level-up. Earlier merges now contribute, but the growth becomes linear.

  • With this version’s +1 starting bonus, three level-ups would reach +4 Poison. Under the old rule, three level-3 milestones would double the starting +1 three times to +8; those totals require different milestones.

Before using an older guide

Track completed level-ups when updating the old strategy. The +1 starting value here is historical; Chemist’s current passive starts at +3.

Now that that there are items and trinkets to lower the shop rank, it's become too easy to hit thousands or even millions of poison on Chemist's ability.

Chemist (OLD) Your Toxic monsters have +1 Poison. When any monster levels up to level 3, double this effect. (NEW) Your Toxic monsters have +1 Poison. When any monster levels up, this effect gains +1 Poison.
