ToME: the Tales of Maj'Eyal

Zigur is unavailable, so I assume it's not possible?

if you unlearned all your talents, and tried to find the right escort, i think one of them could teach you mindstars, if you betrayed them.
Otherwise, gathering money learn from zigur would take too long, and you would have to make some of the talents permanent.

EDIT i believe its the lone alchemist you need to betray.

Zigur doesn't normally even appear - would it appear if I didn't allocate starting points?

Its the same as archmage I think, the problem is Teleport:Point Zero spell. Even if you unlearn everything you start with this spell so zigur wont appear. The only way to get around this is to create a race that bypasses chronomancer starting zone (dunno if its possible). Dwarf and Yeek zones normally override class related start zones, Undead zones also override but dont make Zigur appear since they are, well undead. So you basically have to roll a dwarf or yeek, unlearn all spells and go to world map for Zigur to appear. Please note that everything i wrote in this post is from my experience as archmage, I didnt test it on TW but the logic should be the same.
PS: This only works if "assign talent points at start" is enabled and if you manually remove points for some reason.

You can enter zigur with shalore archmage with skills unlearned -you just can't interact with anyone. Well, except Myssil who will try to kill you if you enter her place .

TW can enter and buy things with skills unlearned so mindstar TW is possible if you for some reason want it. This works for shalore etc. too (excluding undead ofc).

Also there is bug if you disable the autoassign of initial points, autoassign must be on (unless it's fixed).

Thanks for claryfing things up Mankeli, the bug still exists as far as I know.

What's that bug? i've pretty much always used that option and i haven't noticed anything extrange

option to auto assign talents on start.
if you turn it off, you will instead get points instead i believe.
although, some talents should be possible to turn off.

things like "teleport zero/anglowen", cannot be learned anywhere, so you either start with it, or you don't.
i have not tested that one.

edit.
checked, you still get the teleport talent for free.
