Those are NOT what I have been suggesting. Again, please take into account the fact that I took your suggestions into account and amended my proposal.
Here it is again:
- Easier language learning while there, for everyone. People can attune to the Mythal for 2
- 500xp, 1 month of devotion to the OG and a personal sacrifice 2 points of 1 stat of their choice, which cannot recover naturally or be restored through magic).
- Finally, characters attuned to the mythal may activate any of the following spells by command word, exactly as if it were an ability of a magic item in the character's possession: detect aberration, detect disease, detect magic, detect poison, detect undead, discern lies.
- Targets of spells with the [cold], [evil] and [death] descriptors can reroll failed saves and take minimal damage from them.
- The following spells are continually in effect throughout the area of the mythal, much like a spell fixed to a hallow or unhallow effect: protection from evil.
This is a Mythal seed that can later be added to. I suggest trying to increase the spells available to attuned characters, and maybe even the spells attached to it. Silverymoon-lite is a goal! Weirder effects like "it's impossible to steal souls inside" or "our buffs are protected while inside it" are also a goal.
