Zosima

When he shows up

BazaarDB's 20.1 card puts him on days 4-5 and again from day 8 onward, and also as the level-11 level-up reward. Partner Portal can offer him too. The wiki still has a Zosima page and agrees he is the skill merchant tied to Mak. I have those two, so the role is settled. I do not have an official sentence for how many skills he displays at once, so that cell stays empty even though the pool size is 27.

Twenty-seven is the Mak-only list, not a sample of every skill in the game. The database counted 523 skills overall. Walking into Zosima for a Vanessa weapon skill is the wrong door; Old Zane is hers. If your board is potions, reagents, poison, or regen, this is the node that changes the run, because a skill does not occupy a square and Tomb of the Ancients already wants other relics beside it.

When to skip him

Skip the visit when you are short on gold and the skill you own already enables the relic. Eight gold is a reroll, not a tip, and a second skill does not replace the first one you bought unless the client says so. I have not seen a rule that stacks two Zosima skills, so I will not write one. Also skip him on a Vanessa or Dooley run: the pool is Mak's. The wiki's older pages sometimes blur trainers together; the 20.1 card does not.

Patch 20.1's named hotfix list does not mention Zosima. I am not inventing a November nerf. If his days move in a later database footer, this paragraph should move with the footer, not with a rumor.
