ToME: the Tales of Maj'Eyal

1) Is there any way to "unsummon" golem (other than geting him killed)?

2) By doing traveller quests we can unlock new talent trees (also for our golem), but after unlocking couple trees for ourselves we no longer have a choice to unlock any - EVEN FOR OUR GOLEM - only adding stats remains. I think its normal to make some cap for number of talents we can learn, but why this cap is shared (?) with our golem?

3) Cursed Aura - So in the description of the skill i have found that at level 10 we can put curse on such objects as amulets/rings/arrows etc. But how can I upgrade the skill to lvl 10? As all skills it have only 5 lvls. I'm guessing that it can be upgreaded by some item? But most of them adds like +2 to given skill or such. The only skill that i have upgreaded to high lvl is "Exotic Weapon Mastery" - which i think was at lvl 15 when i was done. I know that mastery of the tree increases our lvl (so when we have 1.2 in talent tree and 5 lvl skill then its like having lvl 6 - but to get skill lvl 10 i would need 2.0 at talent tree - which is kind of impossible). I also heard that the max skill lvl go up in Infinite Dungeon after lvl 50 each 10-30 lvls. Does that mean that Cursed aura at lvl 10 cannot be achieved in Main Campain?

1) there is not... well, there in the advanced golemancy there is talent to drain life from him, and then later there is one to revive it.

2)if you mean ESCORT quest, i believe it only checks whether you have it, to give the option.
then, if you pick the option, it ask for you or golem.
also, while escort types are random, their rewards are not. an injured warior will always offer conditioning, if you dont already have it, and anorithil will always offer light, if you don't already have it and an alchemist will always offer stone alchemy, if you dont already have it.
2)b if you make use of NO magic, and have visited zigur, you will have the option to betray your magic using escorts, which results in a different set of rewards for you to chose from.

3)... what? lvl 10? 0.o you canot get lvl 10 without mods. that cant be right.
edit
uhm... its: defiling touch
Level 1 — weapons
Level 2 — body armor and cloaks
Level 3 — shields and helmets
Level 4 — gloves, boots and belts
Level 6 — rings
Level 7 — amulets/necklaces
Level 8 — lites
Level 9 — tools/totems/torques/wands
level 10 — ammunition
i don't think you are actually intended to reach lvl 10 in vanilla, but it is possible with mods.
extra edit
"xxxx amulet of mastery" gives you +0.2 to +0.5 (or somewhere there) mastery to a random category.
if you roll a strong mastery amulet for it, and if its starts at 1.3, and you add 0.2 with a category point, you might be able to get there in vanilla.

2) Still - its "bad" that when we already have a talent we can't give it to our golem. There should be a choice anyway - and it would simply increase our mastery with the given tree (if we choose our character) or new skill tre for golem.

3) Well you can have exotic weapon mastery of high lvl - 5 as normal talet lvl and 5 or 10 (dont remember right now) from Legacy of the Naloren Prodigy and the artifact.

Bummer.

2) i am prett sure you are not even supposed to give any talents to a golem.
its probably a remnant of some age old code, that is still there and no one bothered.
golem never gains any generic or category points, so giving him a locked category is absolutely and utterly useless anyway.
and even if you give him a point into some talent, like light, he will never use it, as far as i know.
a passive might work, since it is active regardless of whether you want it or not, and same with sustain, although you need to activate it manually. An active will not work.

3) exotic is unique like that.

K - Thanks guys for replies

In the infinite dungeon I think you can put more than 5 points into talents, but that might be an addon.
