Grimtoad was on my box, or an imposter Grimtoad and mentioned there was lots of out of era Alchemy in Grobb. It's been eating away at me so. I have never done it, and apparently everything is fucked. BUT I think I found a solution.

The one on the left is P99 the main alchemy merchant in Grobb, the one on the right is an Oggok Alchemy merchant on my box. So I only need to remove the out of era merchants and copy this loot table to the Grobb dude.
I have the exact p99 NPC Alchemy list in order. I also went and removed out of era mobs in Grobb and Oggok and Rathe MTS that human on the main stretch I got him Grimtoad I know that's the one you meant I ran past him a few times.
In another hour I will have 100% classic P99 Alchemy merchants.
