ToME: the Tales of Maj'Eyal

my question is, can you get the extra slots for your gear to put in tinker crafts(like grounding strap) ? and do you have to buy this feature in the tinker cave ?

Thanks for the answers, guess I have to restart now.

You have to spend a category point in the cave to get access to the tinker stuff, do you ?

Do you get access to everything the tinker classes have (salves, steam generators, and can you upgrade your gear with tinker crafts) ?

I looked on every single ice tile, its not there.
I took the Last engineer standing (talent) as rewad from the escort. Do I have to choose something else for the cave to appear ?

I just unlocked tinker escorts for the main campaign. I found my tinker escort in old forest and saved him.
Where is the cave now that should appear on the world map ? I already explored everything on the first continent. Is it on the second continent ?

Why does everybody say Wyrmic is so bad ? I got my first and only insane victory with Wyrmic. A little bit difficult in the begining but after lvl 20 or so it was very easy until the last level of the game. I was incredibly tanky thanks to Antimagic/Fungus and alot of armor and 100 % stun resistance...
