I find it unfortunate the pre-essence versions of this mod are not available anymore :(
Personally I can't have a fraction of the fun with the overhauled changes

Why is it commented out and why does the description not mention it?

All the changes are dank, though turning stone warden stuff into teleports makes them fizzle in some areas it seems.

Although I am not sure how to replicate this bug, here is what happened: I am currently playing oozemancer - removing buffs debuffs and sustains all around. One random rare casted effigy in the middle of a fight on me, I did not notice as I had a lot of oozes around. After fight it does not disappear (maybe I managed to remove some buff/debuff/kill its caster, I dont know for sure). Instead it stays permanently and with -50% - 0% resistances acts as extreme damage sponge/run ender. Class is really fun to play though and I hope you manage to repair this one talent.

Thanks for the update, I'm running amok with an Outlander now. Never had to worry about it before, but is there a limit on the number of talents a character can have, before ToME decides to halt and catch fire? An observation - the description says talents from rare monsters may be come available, but I'm getting them from very ordinary varmints like ants, snakes, etc, as well. Intended? Finally, what does the character rank DO? Is it just an otherwise insignificant placeholder count to require five points for the prodigy?

Holy crap, they made siding with the assassin lord actually good 0_0

I'm glad I found this little spoiler I would have never found this myself

Yeah, when starting out, Adventure mode makes the most sense. It's a tough game, and it only gets tougher after the Master. So give yourself some leeway to make mistakes or walk unknowingly into deathtraps (there are some really nasty ones out there if you aren't willing to spoil yourself by reading up on the game.) Hell, lots of people -- me included -- prefer Adventure mode even after knowing the ins and outs of the game. If you don't have unlimited time to spend playing, it can be frustrating starting from scratch every time you die even when you're playing perfectly. There are always going to be situations where you're just whacked up side the head by the RNG.

Congrats on making it to the Master. Next time, the best course would be to scan for monsters (if you have an item or talent that can do that), try to clear as much of the level as you can before taking on the Master and, when in doubt, teleport away immediately after killing him the first time. You can rest up and, since he's at full health already, you don't have to worry about him taking advantage of your absence to heal up again. Just remember -- he *will* be coming to look for you, so keep an eye out.

"Verdant song", "Transplant" and "Botanikal Strike" not affecting Treants, summoned by Thalorn's "Nature's Pride", despite that they are plants.

The Assassin Lord is a pretty damned good body for clearing most T1s and T2s. Now that the level requirement for the quest has been raised significantly, you won't be using him to wipe most T1s, granted, but, alternatively, he's scaled up and you do have more Possessor talents trained and can therefore make better use of him (including multiple bodies.) I've cleared the entire West with just the AL's body used judiciously and clicking Shadowstep (to weaken or kill the strongest opponent in sight) and Shadow Veil a lot (though also judiciously.) So killing him has a significant advantage, especially if you're playing higher difficulties (which, as a Possessor, you should be) and are likely to be getting great loot from drops anyway.

Edit: I do feel compelled to note that I'm just talking main sequence dungeons. You're not going to clear the Elven Ruins or the Ruined Dungeon or the like with the AL unless you're getting serious help from add-ons (which I currently am, just on a lark, by using an add-on that allows Possessor talents to be chosen by an Adventurer, which makes for a seriously OP combination. Don't try to take out the Grand Corrupter with just an ordinary AL possession.)

I fixed 'Great Caller' to have proper bonus!
And the Dragon is not intended to be bonded, so I made it not be selectable by 'Strengthened Bond'. Thank you.

If you know what you are doing with egos the assassin lord is significantly better. You might get something good with the merchant but you will get something great by rerolling. You can make completely broken items with it.

For me, the Trollmire Renegade was on Trollmire 2, not with Bill. So maybe they are randomized? Or randomized per dungeon? I hope I don't have to go search all the t1 dungeons I skipped.
